Q. 17.89 - An Introduction to General, Organic, and Biological Chemistry

Question

Answer the following questions for the given section of DNA:

a.Complete the bases in the parent and new strands 

b. Using the new strand as a template, write the mRNA sequence.

c.Write the three-letter symbols for the amino acids that would go into the peptide from the mRNA you wrote in part b.

Step-by-Step Solution

Answer

The answers to this question is:

a)  the bases in the parent and new strands  N: TCCAGCGGA P: AGGTCGCCT 

b) The mRNA sequence generated is as follows: AGGUCGCCU

c) AGGUCGCCU for the amino acids.

Part (a) Step 1: Given information

We have to complete the remaining strands.

Part (a) Step 2: Explanation

Adenine (A) partners with thymine (T), and cytosine (C) couples with guanine (G) in DNA (G).

As demonstrated below, the parent and new strands are completed: N: TCCAGCGGA P: AGGTCGCCT

Part (b) Step 1: Given information

We have to write the mRNA sequence.

Part (b) Step 2: Explanation

Except for A in DNA, which is linked with U in RNA, the nucleotides in mRNA are complementary to those in DNA.

As a template, use the new strand. TCCAGCGGA

The mRNA sequence generated is as follows: AGGUCGCCU

Part (c) Step 1: Given information

We have to write the three-letter symbols for the amino acids that would go into the peptide from the mRNA.

Part (c) Step 2: Explanation

The amino acid sequence Arg-Ser-Pro is represented by the three-letter characters AGGUCGCCU for the amino acids that would go into the peptide from the mRNA mentioned.
