Which of the following is NOT associated with Okazaki fragments?

A.
lagging strand

B.
ligase
C.
bases added to the 3’ end

D.
continuous replication

E.
DNA polymerase III

Answers

Answer:

The correct answer is - D. continuous replication.

Explanation:

Okazaki fragments are short DNA sequences synthesized in the lagging strand as DNA polymerase enzyme is able to synthesize only from 5' to 3' so nucleotide can not bind on 5' end but only 3' end and the DNA strands are antiparallel.

They are short fragments of DNA synthesized from RNA primers on the lagging strand and combined by the ligase enzyme. Okazaki fragments show a discontinuous manner in the synthesis of DNA.

The correct answer is D. continuous replication as they don't have it.

Okazaki fragments are brief DNA sequences synthesized withinside the lagging strand as DNA polymerase enzyme is capable of synthesizing simplest from 5' to 3^ high SO nucleotide can't bind on 5' cease however simplest 3' cease and the DNA strands are antiparallel.

They are brief fragments of DNA synthesized from RNA primers at the lagging strand and blended via way of means of the ligase enzyme. Okazaki fragments display a discontinuous way withinside the synthesis of DNA.

What are  Okazaki fragments?

Okazaki fragments are small sections of DNA that might be fashioned all through the discontinuous synthesis of the lagging strand all through DNA replication. They are essential due to the fact they permit each daughter strand to be synthesized, which is vital for molecular division.

Thus it is clear thsat Okazaki fragments are not associated with continuous replication.

5. Which fur color seems to have the greatest overall selective advantage? Use data collected from both dark-colored and light- colored substrates to support your answer.

6.What environmental change gave a selective advantage for one coat color over another?

7. In a separate study, 76 rock pocket mice were collected from four different, widely separated areas of dark lava rock. One collecting site was in Arizona. The other three were in New Mexico. Dr. Nachman and colleagues observed no significant differences in the color of the rocks in the four locations sampled. However, the dark-colored mice from the three New Mexico locations were slightly darker than the dark-colored mice from the Arizona population. The entire Mc1r gene was sequenced in all 76 of the mice collected. The mutations responsible for the dark fur color in the Arizona mice were absent from the three different populations of New Mexico mice. No Mc1r mutations were associated with dark fur color in the New Mexico populations. These findings suggest that adaptive dark coloration has occurred at least twice in the rock pocket mouse and that these similar phenotypic changes have different genetic bases. How does this study support the concept that natural selection is not random?

8. To determine if the rock pocket mouse population is evolving, explain why it is necessary to collect fur color frequency data over a period of many years.

Answer:

1)

frequencies of light-colored mice  ≅ 0.74 frequencies of dark-colored mice  ≅ 0.26

2)

frequencies of light-colored mice ≅ 0.13 frequencies of dark-colored mice ≅ 0.87

3)

p² ≅ 0.02 q² ≅ 0.74 2pq ≅ 0.24

4)

q² = 0.13 p² = 0.4 2pq = 0.46

5) The dark-colored fur seems to have the greatest overall selective advantage

6) Dark lava changed the color of the substrate, from light to dark.

7) Because to produce dark color, animals from the different regions suffered different mutations that drove them to have almost the same dark fur color.

8) To see if the mice population is evolving. If it is, there will be a change in the allelic and genotypic frequencies over the years. If it is not evolving, the frequencies will keep equal through the years.

Which properties of water are most responsible for the capillary action in plants?

Answers

Capillary action occurs because water is sticky, thanks to the forces of cohesion (water molecules like to stay close together) and adhesion (water molecules are attracted and stick to other substances)

Answer:

The property of "cohesion forces" of the water makes them responsible for the capillary action in the plants.

Explanation:

Water molecules in the soil get pulled into the plant through roots and travel over the vessels and tubes in the stem to various parts of the plant. Leave surface have small pores, named as stomata or guard cells that will help in transpiration or evaporation. This process of transpiration will help the ground water to travel opposite to the gravity and travel all parts of the plant body carrying minerals and essential food particles.

Two polypeptides, X and Y, have similar tertiary structures. X normally exists as a monomer while Y exists as a tetramer, Y4. What differences might be expected in the amino acid composition of X versus Y

Answers

Answer:

Due to number of amino acids.

Explanation:

The main differences might be expected in the amino acid composition of X versus Y because the X polypeptide is made up of one smaller unit of amino acid while on the other hand, Y polypeptide is made up of four smaller units of amino acids. The  name of X is monomer which means composed of one amino acids while Y exists as a tetramer which means it has four amino acids. So we can conclude that the main difference between X and Y is the presence of  number of amino acids.

Amino acids are organic compounds that are formed of amino, carboxylic and a side group. They bond to form protein structures.

The amino acids fold in various structures like primary, secondary, tertiary etc. The basic contrast in an amino acid arrangement of polypeptide X and Y is that the X is made of small units while Y is made of larger units.

X polypeptide is a monomer that is it only has one unit of amino acid while Y is a tetramer that is it has four-unit of amino acids.

Therefore, the number of amino acids is the main distinction between X and Y tertiary structures.

convention cells hbnmb,

Answers

Answer:

convention cells

Explanation:

In the field of fluid dynamics, a convection cell is the phenomenon that occurs when density differences exist within a body of liquid or gas. These density differences result in rising and/or falling currents, which are the key characteristics of a convection cell. When a volume of fluid is heated, it expands and becomes less dense and thus more buoyant than the surrounding fluid. The colder, denser part of the fluid descends to settle below the warmer, less-dense fluid, and this causes the warmer fluid to rise. Such movement is called convection, and the moving body of liquid is referred to as a convection cell. This particular type of convection, where a horizontal layer of fluid is heated from below, is known as Rayleigh–Bénard convection. Convection usually requires a gravitational field, but in microgravity experiments, thermal convection has been observed without gravitational effects.

In fruit flies, the phenotype for eye color is determined by a certain locus. E indicates the dominant allele and e indicates the recessive allele. The cross between a male wild-type fruit fly and a female white-eyed fruit fly produced the following offspring.

Wild Type Male Wild Type Female White-eyed Male White-eyed Female Brown-eyed Female
F1 Generation 0 45 55 0 1

The wild-type and white-eyed individuals from the F1 generation were then crossed to produce the following offspring.

Wild Type Male Wild Type Female White-eyed Male White-eyed Female Brown-eyed Female
F2 Generation 23 31 22 24 0

Required:
a. Determine the genotypes of the original parents (P generation) and explain your reasoning.
b. Use a Chi-squared test on the F2 generation data to analyze your prediction of the parental genotypes.

Answers

Answer:

The genotypes of the original parents are

Male: X⁺Y   Female: X⁻X⁻

The Chi-square analysis leads us to accept the prediction of the parental genotypes.

Explanation:

Due to technical problems, you will find the complete explanation in the attached files.

(a) The genotypes for the original parents (P generation) are

Male: X⁺Y  

Female: X⁻X⁻

(b) The prediction of the parental genotype is accepted by the Chi-squared test analysis.  

What is the eye color pattern in fruit flies?

Drosophila Melanogaster is a fruit fly with abnormally big, brightly colored eyes.

The range in color from red to sepia to white reveals a lot about the genetic makeup of the fly.

(a)  E = + ⇒ Dominant allele coding for wild-type eyes

     e = - ⇒ Recessive allele coding for white eyes

Now, Crossing the : male wild-type with a female white-eyed

(Parental)   =  X⁺Y x X⁻X⁻

(Phenotype) =   wild   white

(Gametes)  =    X⁺ Y X⁻ X⁻

(Punnett square)  =  X⁺ Y

X⁻   =  X⁺X⁻  X⁻Y

X⁻   =  X⁺X⁻   X⁻Y

In (F1)generation = 2/4 = 1/2 = 50% of the progeny are expected to be wild-type females.

And 2/4 = 1/2 = 50% of the progeny are expected to be white-eyed males.

Thus, the percentages are almost 50:50, as the expected ones.

So, the genotypes of the original parents are

Male:      X⁺Y

Female:  X⁻X⁻

(b) Using Chi-squared test :

Observed fruit fly type:

Wild Type Male - 25

Wild Type Female - 31

White-eyed Male - 22

White-eyed Female - 24

Expected fruit fly type:

Wild Type Male - 25

Wild Type Female - 25

White-eyed Male - 25

White-eyed Female - 25

Now, chi square [tex]= \sum\dfrac{(O- E)^2 }{E}[/tex]

By putting numbers in the formula, we are getting

Wild Type Male - 0.16

Wild Type Female - 1.44

White-eyed Male - 0.36

White-eyed Female - 0.04

Now, X² = 0.16 + 1.44 + 0.36 + 0.04 = 2

Critical value = 7.82

X² (2) < critical value (7.82)

Thus, this is the evidence to accept the given hypothesis.

Answers

This question is incomplete because the images a section 2 are not given. I searched for the complete question but could not find it. However, based on my knowledge and the characteristics of the tundra this is the answer.

The correct answer is C. The climate is harsh, which limits the number of species that can live there.

Explanation

The tundra is the name of an ecosystem that occupies a fifth of the earth's surface, mainly in the northern hemisphere, this is characterized by having a frozen subsoil that limits the emergence and growth of natural vegetation and trees. This ecosystem is the coldest on the planet due to its location near the poles, its landscape is characterized by a layer of snow that covers most of the ground. In addition, the climatic conditions are extreme, which limits the number of plant and animal species that can live there. According to the above, the correct answer is C. The climate is harsh, which limits the number of species that can live there.
