Chapter 23, Problem 23.95SP

Interpretation Introduction

Interpretation:

The complementary DNA sequence should be determined for the given RNA sequence.

Concept introduction:

RNA is the abbreviation term of “Ribonucleic Acid”. It is a complex molecule found in all living things.

A base is nitrogen containing heterocyclic compound which is found in DNA and RNA.

There are mainly four nitrogen bases in RNA.

1. (1) Adenine
2. (2) Guanine
3. (3) Cytosine
4. (4) Uracil

In RNA, Adenine always makes a double bond with uracil ($A=U$) and cytosine always makes triple bond with guanine $\left(G\equiv C\right)$

In DNA, Adenine always makes a double bond with thymine ($A=T$) and cytosine always makes triple bond with guanine $\left(G\equiv C\right)$

Central dogma in molecular biology is,

                     $\text{DNA}\stackrel{\text{Transcription}}{\to }\text{RNA}\stackrel{\text{Translation}}{\to }\text{}\text{Protein}$

Transcription is the process of creating an equivalent RNA copy of a sequence of DNA. Transcription results in an RNA complement that includes Uracil instead of Thymine.
