Chapter 27, Problem 27.49CP

Interpretation Introduction

Interpretation:

The base sequence which would be sticky with the given sequence should be written.

Concept Introduction:

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

There are mainly four nitrogen bases found in DNA and they are,

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

Short stretches of single stranded DNA are sticky (complementary) to each other. If both ends are cut with the same enzyme, the sticky ends will stick together by complementary base pairing, forming hydrogen bonds.

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