I kneed you know what the answer is

Answer:

a) Particular codons are generated in predictable ratios with random RNA polymers containing specific ratios of different nucleotides.

b) Poly(A) RNA directs the synthesis of only polylysine in vitro.

d) The codon table was completed by using RNA polymers of defined sequences.

Explanation:

A polynucleotide molecule is defined as the biopolymer which is composed of thirteen nucleotide monomers or more monomers which is covalently bonded in the chain.

While using the synthetic polyneuclitide in the cracking of the genetic code, the translation of a [tex]\text{poly(A) RNA tail}[/tex] that results in synthesis of the poly-lysine in the lab.

Some of the particular codons are produced by some specific ratios of a different nucleotides. This can be present in the different RNA polymers. Codon table includes the RNA polymers that contains nucleotides in some specific ratios.

Thus, the options (a), (b) and (d) are correct.

The base of the flower where it is attached to the rest of the plant is the:Receptacle

Peduncle: The stalk of a flower. Receptacle: The part of a flower stalk where the parts of the flower are attached.

Explanation:

Flowers may be directly attached to the plant at their base (sessile—the supporting stalk or stem is highly reduced or absent). The stem or stalk subtending a flower is called a peduncle.

Answer:

receptacle

Explanation:

it is that part of the flower to which the stalk is attached to.it is small and found at the centre of the base of the flower

The following best explains why the Galápagos islands are still used for evolution research today most species found on the islands are only found in this geographic area, which allows researchers to easily isolate their studies.

Galápagos are a extraordinary vicinity to observe evolution, still, because, remarkably, numerous islands and their population are near being withinside the completely herbal state, with very little have an impact on of human activities,” says the evolutionary biologist and Princeton University professor emeritus Peter Grant.

Six hundred miles off the coast of Ecuador lie the volcanic islands of the Galápagos, well-known for a wealth of particular flora and animals discovered nowhere else withinside the world. The Galápagos Islands have been the supply of Darwin's concept of evolution and stay a valuable residing laboratory for scientists today.

I asked the same question

Harvey placed the sea urchin cells in a hypersonic solution in order to see the behaviour of the cell in the hypersonic solution.

In 1940 Ethel Brown Harvey evolve a technique for separating embryonic sea urchin cells. She took a pair of embryonic cells to develop from the first cell division after Harvey's fertilization. She settles the pair of cells in a hypertonic solution, carrying double the amount of salt as that contained in seawater. Most sea urchins produce a group of early embryonic cells which is known as micromeres. Small blastomeres Harvey that form by unequal cell division at the vegetal pole of the early embryo. Harvey Sub-Sea is the first that indicated Maritime Labor Convention compliant.

So we can conclude that Ethel Brown Harvey developed a technique for dividing embryonic sea urchin cells.

Answer:

The N-terminal aminoacid is Metionin.

Explanation:

Before answering the question, let us remember the meaning of the term amino terminus. Terminus refers to the extremes of the polypeptide. During translation, rRNA and tRNA read mRNA in 5´ to 3´ direction. The first extreme to be translated carries the amino-terminal group, while the other extreme carries the carboxy-terminus group.

Conventionally, proteins are written from left to right, beginning by the N-terminal extreme carrying the free amine group, and ending by the C-terminal extreme carrying the carboxyl free group. However, we need to know that the free amine group actually places at the end of a protein.

Transcription:

Transcription occurs in the nucleus where the template DNI strand is read in direction 3´→ 5´ to build the mRNA molecule in direction 5´→ 3´.

template DNI strand  ⇒   5'-TAGAACGCCTCGAAATTTCATACT-3'

                      mRNA   ⇒  3´-AUCUUGCGGUGCUUUAAAGUAUGA- 5´

Translation:  

Translation occurs in the cytoplasm. rRNA and tRNA read mRNA in the direction 5´→ 3´ to build the protein.

Protein synthesis initiates in the AUG start codon -Metionin-, and ends when reaching either of the stop codons UAA, UAG, UGA.  

The first portion of mRNA is not read nor translated. This is the untranslated region (UTR), placed before the strat codon.

mRNA   ⇒  3´-AUCUUGCGGUGCUUUAAAGUAUGA- 5´

Remember that transcription occurs from 5´ to 3´ extremes, so we need to read the codons in this direction too, beginning on the 5´ extreme.

First, we need to find the initiation codon: AUG coding for Metionin.

mRNA   ⇒  3´-AUCUUGCGGUGCUUUAAAGUAUGA- 5´

                                                                        Met

mRNA   ⇒  3´-AUCUUGCGGUGCUUUAAAGUAUGA- 5´

                                                                Lys  Met

mRNA   ⇒  3´-AUCUUGCGGUGCUUUAAAGUAUGA- 5´

                                                        Phe   Lys  Met

mRNA   ⇒  3´-AUCUUGCGGUGCUUUAAAGUAUGA- 5´

                                                 Arg  Phe  Lys  Met

mRNA   ⇒  3´-AUCUUGCGGUGCUUUAAAGUAUGA- 5´

                                        Gly  Arg  Phe  Lys  Met

mRNA   ⇒  3´-AUCUUGCGGUGCUUUAAAGUAUGA- 5´

                                Val  Gly  Arg  Phe  Lys  Met

mRNA   ⇒  3´-AUCUUGCGGUGCUUUAAAGUAUGA- 5´

                       Leu  Val  Gly  Arg  Phe  Lys  Met

The N-terminal aminoacid is then Metionin.

Pollen grains are also adapted for insect pollination. Some pollen grains are hairy or spiky, and others are sticky, so they attach to the insect. The anthers dangle in the breeze, and the pollen is blown away. The pollen grains are very small and light so they are easily carried on the wind.

Answer:

The kind of genes an organism possesses is determined by the order of the nucleotide bases in the organism's DNA.

Answer:

The kind of genes an organism possesses is determined by the order of the nucleotide bases in the organism's DNA. ... The order of bases as you go down the rungs of the ladder determine what genes an organism will have, and therefore, what traits it will have.

Explanation:

Fun facts:

Genes carry the information that determines your traits which are features or characteristics that are passed on to you — or inherited — from your parents. Each cell in the human body contains about 25,000 to 35,000 genes. ... And chromosomes are found inside cells. Your body is made of billions of cells.

Answer:

2.75 x 10³ cm³

Explanation:

Volume can be measured in both liters (L) and cubic centimeters (cm³), however,

1 liter = 1000cm³

According to this question, a partly full paint has 2.75 liters of paint left in it.

Since 1 liter = 1000cm³

2.75 liters = 2.75 × 1000

2.75 × 10³ cm³ is left.

Answer:

d) The antigen-presenting cell encounters and processes the antigen.

e) With the antigen, the antigen-presenting cell migrates to the nearest lymph node.

b) The antigen-presenting cell displays the antigen to the T cells.

c) The T cells initiate the immune response if the antigens are viral proteins or abnormal antigens.

a) Infected or malignant cells are then destroyed before they can do further harm to the body.

Explanation:

The antigen-presenting cells (e.g., dendritic cells, macrophages) are cells of the immune system that mediate cellular immune responses by processing and presenting antigens (i.e., peptides components of pathogens) to T lymphocytes. The antigen-presenting cells travel through lymphatic vessels from the site of infection to the lymph nodes where they present antigens to naive T cells, i.e., T cells that have matured but have not yet encountered their corresponding antigens. This presentation facilitates the clonal expansion of T cells that are specific for the antigen which acquire effector functions in order to destroy infected cells. This process is known as immune clearance and is associated with the apoptosis of antigen-specific T cells.

Explanation:

The Richter scale is a scale of numbers used to measure the magnitude of an earthquake, which is based on the size of its seismic waves. This scale indicates a number to quantify the total seismic energy released by an​ earthquake. The Richter magnitude scale is a base-10 logarithmic scale, thereby a difference of one (1) point in the scale of magnitude corresponds to a 10-fold increase in amplitude. For example, based on the Richter scale, a magnitude-8 earthquake is 100 times greater than a magnitude-6 and 1000 times greater in amplitude than a magnitude-5.
