What carries the three unpaired bases that are collectively called the anticodon?

1 answer:

4 0

As the ribosome reads each codon of mRNA, it directs tRNA to bring the specified amino acid into the ribosome. Each tRNA molecule carries just one kind of amino acid. In addition, each tRNA molecule has three unpaired bases, collectively called the anticodon—which is complementary to one mRNA codon.

aksik [14]

Answer:

For sample A, A=17.7 %, T=17.7 %, G=32.30%, C=32.30%

For sample B, A= 28.9%, T=28.9%, G= 21.10%, C= 21.10%

Explanation:

The composition of nitrogenous bases in DNA is calculated using the suggestions proposed by the results of the experiment performed by Erwin Chargaff.

He found that in a DNA sample the composition of purine to pyrimidine is 1:1. This indicates that the amount of purine equals pyrimidine. This can be presented as purines + pyrimidines= 100. Also, adenine binds thymine and cytosine binds guanine.

In the given question,

For sample A

A= 17.7 %, Therefore, thymine will be = 17.7 %,

A+T= 35.40%

Now, G+C=100- 35.40%

G+C= 64.60%

content of G= 64.60/2= 32.30%

content of C= 32.30%

For sample B

T=28.9%, A will be= 28.9%

A+T= 57.80%

G+C=100-57.80%

G+C= 42.20%

Thus content of G will be= 42.20/2=21.10

content of C= 21.10%

Thus,

For sample A, A=17.7 %, T=17.7 %, G=32.30%, C=32.30%

For sample B, A= 28.9%, T=28.9%, G= 21.10%, C= 21.10%

I think you forgot to give the options along with this question. I have researched with the question and have found the options as well. Hope it helps you in your study. Among the choices that i have come up with, the option that says that temperate deciduous forests are less open than tropical rain forests.

A dihybrid cross is performed between plants that differ in two Mendelian traits: Stem length (T or t) and flower coloration (R

Dahasolnce [82]

Answer:

A. 3/16

Explanation:

The four possible outcomes for Stem length are:

Tt, tT, TT and tt.

The dominant trait (tall stems) will manifest itself in 3 out of 4 outcomes, so its ratio is 3/4.

The four possible outcomes for flower coloration are:

Rr, rR, RR and rr.

The non-dominant trait (white flowers) will manifest itself in 1 out of 4 outcomes, so its ratio is 1/4.

Multiplying both ratios gives us the ratio of offspring that have tall stems and white flowers:

$\frac{3}{4}*\frac{1}{4}=\frac{3}{16}$

Therefore, the answer is A. 3/16
