Q. 17.40 - An Introduction to General, Organic, and Biological Chemistry

Question

Write the corresponding section of mRNA produced from the following section of DNA template strand:

$T A C G G C A A G C T A$

Step-by-Step Solution

Answer

Section of DNA template$-T A C-G G C-A A G-C T A-$

Corresponding section of mRNA$-A U G-C C G-U U C-G A U-$

Step 1: Introduction

Nucleotides are organic molecules made composed of a nucleoside and a phosphate. These are isomeric units of the deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) nucleic acid polymers, which are both fundamental macromolecules in all living creatures on Earth. Nucleotides are obtained from food and synthesised by the liver from common substances.

Step 2: Explanation

Each nucleotide from DNA binds to the ribonucleotide in the following way:

$G\to C,C\to G,A\to U,T\to A$

DNA template part$-T A C-G G C-A A G-C T A-$

mRNA section that matches$-A U G-C C G-U U C-G A U-$
