A sequence of DNA has 120 nucleotides (it is not a complete sequence).
How
many amino acids would be in the resulting polypeptide chain?
a. 120 amino acids
b. 240 amino acids
c. 40 amino acids
d. 12 amino acids

Answers

Answer:40

Explanation: a codon is three nucleotides. Provided that the sequence does not include a STOP codon, the polypeptide would have 40 amino acids

40 amino acids would be in the resulting polypeptide chain of a sequence of DNA that has 120 nucleotides.

CODONS:

A codon is a triplet nucleotide sequence in an mRNA molecule that encodes a particular amino acid. Each codon specifies an amino acid.

A codon is made up of three nucleotides, whose combination determines the amino acid that is encoded.

According to this question, a sequence of DNA has 120 nucleotides. This means that the number of codons that is accommodated in this sequence is 120/3 = 40 codons.

Since 1 codon specifies 1 amino acid, therefore, 40 codons will specify 40 amino acids.

Which of the following is conical movement in which the distal end of a structure moves in a circle and the proximal end remains relatively fixed?
A. Protraction
B. Rotation
C. Circumduction
D. Retraction

Answers

Answer:

The correct answer is OPTION C (Circumduction)

Explanation:

Circumduction is motions without clear opposites of the part of the body, an example is rotating the hand from the wrist. The answer is circumduction because this type of movement ensures the distal end of a bone moves in a circle while the proximal end remains relatively stable is particularly found in bones where the movements of the joints are opposite to each other example is the ball and socket joint movement. For circumduction to take place, the degree of distance between two bones of the body has to be decreased and sometimes straightened to increase the level of movement or motion produced, there must be a movement towards the middle of the body and sometimes joint movement away from the middle of the body. All these movements are in order.

5.The skin functions by protecting the body from basic elements of nature such as water, UV sunlight and wind. ... However, skin in integumentary system acts by maintaining the internal conditions that is required by the body while it is excretory system because it secretes a fluid waste called sweat or perspiration.

6.In order to survive, cells must satisfy some basic needs such as oxygen, water, nutrients, waste removal, and maintaining of homeostasis. Oxygen and nutrients are necessary for different processes inside the cell. For instance, cellular respiration uses glucose and oxygen to form energy in the form of ATP.Water is important for different chemical reactions, as well. Also, the result of different processes, waste is produced and it is important to remove it from the cell. Finally, it is important that cell and whole body conditions do not vary so much and that homeostasis is maintained.

А. The recombinant bacterium will produce human insulin using its own transcription and translation machinery.
B. The recombinant bacterium will not transcribe the human insulin gene because this gene is not normally found in the bacterial genome.
C. The recombinant bacterium will transcribe the gene but will be unable to translate the mRNA.
D. The recombinant bacterium will die because it has been exposed to foreign DNA

Answers

Answer:

А. The recombinant bacterium will produce human insulin using its own transcription and translation machinery

Explanation:

This question is describing genetic engineering, which aims at producing desirable traits in organisms. In this case, the gene that encodes insulin protein in humans is inserted into the plasmid (extra-chromosomal DNA) of a bacterium. The plasmid is then inserted back into the bacterium to become a RECOMBINANT BACTERIUM.

The recombinant bacterium containing the insulin gene will produce human insulin (protein) using its own transcription and translation machinery. This genetic engineering procedure is used to mass produce insulin protein, which is administered as medicine to humans who cannot produce the protein.

Do environmental or genetic factors affect growth of organisms most?

Answers

Answer:

Examples of local environmental conditions could include availability of food, light, space, and water. Examples of genetic factors could include large breed cattle and species of grass affecting growth of organisms. The environment in which an organism lives plays an important role in modifying the rate and extent of growth. Environmental factors may be either physical (e.g., temperature, radiant energy, and atmospheric pressure) or chemical. Organisms and the cells of which they are composed are extremely sensitive to temperature changes; as the temperature decreases, the biochemical reactions necessary for life occur more slowly. A lowering of the temperature by 10° C (18° F) slows metabolism at least twofold and often more.

I copied this stuff from a bunch of different biology websites. It doesn't answer your exact question but I would have to say based on what I typed here it would be the environment that affects the growth of an organism more.

Listen How are channel and carrier proteins similar? Select all that apply.

A. Channel and carrier proteins move substances in a certain direction, regardless of their concentration gradients.

B. Channel and carrier proteins are both types of facilitated transport.

C. Channel and carrier proteins can only move substances in one direction either into the cell or out of the cell.

D. Channel and carrier proteins always move substances from the side of the membrane with the highest concentration to the side with the lowest concentration.

Answers

Answer:

a

Explanation:

A. Channel and carrier proteins move substances in a certain direction, regardless of their concentration gradients.

Channel and carrier proteins are both types of facilitated transport.

Facilitated diffusion is one of the ways of transporting molecules and is characterized by the use of proteins that are inserted in the plasma membrane, such as ion channels and carriers or permeases.

Ions, amino acids and monosaccharides, among many other molecules, cannot cross the plasma membrane, because they are polar or are very large in size.

So, for the cell to obtain or eliminate these substances, the presence of transporter proteins is necessary.

This diffusion is a type of passive transport, because it takes advantage of the concentration gradient of the molecules and does not waste energy.

Ion channels are integral tunnel-shaped proteins, selective for one, two, or three ions.

When a channel opens, ions flow under two principles: the concentration gradient and the electrochemical gradient.

Consequently, when an ion channel opens, the potential difference between the two compartments is altered.

Transmembrane proteins mediate the transport of molecules such as bicarbonate or large, polar, uncharged molecules such as glucose.

The transport through these proteins occurs in favor of the concentration gradient, and by a reversible conformational change of the proteins that allows the translocation of the molecule to the other side of the membrane.

This type of transport is always without energy expenditure and in favor of the electrochemical gradient, it occurs in the following way:

Uniport, a single molecule translocates in only one direction.

Simporte, two molecules that translocate in the same direction.

Therefore, we can conclude that channel and carrier proteins are both types of facilitated transport.

Mr. Morales is teaching a lesson on classification. He says that spiders are classified as a different group than insects because they have eight legs instead of six legs. He explains that spiders evolved first. Mr. Morales also says that having eight legs is the derived trait that separates the two groups. Antonio thinks Mr. Morales is wrong. Which piece of information is Antonio considering?
A.Spiders do not have eight legs.
B.Insects do not have six legs.
C.If spiders evolved first, six legs is the derived trait.
D.Spiders do not have derived traits, since they evolved first.

Answers

Answer: The answer is C

Explanation:

The piece of information that Antonio is considering is that if spiders evolved first, six legs are the derived trait. So the correct option is C.

What are derived traits?

A trait that has been observed in a group of organisms but was not observed or was absent in the previous common ancestor of the group.

These are also the traits that are not present in the group of organisms under consideration but were observed in the previous common ancestors. This is called the secondary loss of traits.

Therefore, derived traits are not only concerned with the development of new traits but also the loss of old traits. Simplicity in a structure or function is a secondary derived trait.

Thus, because the spiders evolved before other insects, the presence of 6 legs in insects is a secondary derived trait as it represents simplicity in structure. Spiders are not derived because they are the common ancestors of the group of insects.

Therefore the correct option is C.
