Chapter 16, Problem 25E

Interpretation Introduction

Interpretation:

The four bases found in DNA and their complementary pairings are to be discussed.

Concept Introduction:

 Nucleic acids act as templates from which all proteins are made. They are long, chain-like molecules consisting of repeating units called nucleotides.

 Each nucleotide has three components: a phosphate group, a sugar group and a base. The phosphate and sugar groups are identical but there are four bases in each nucleotide.

 The nucleic acids are classified into two forms which are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).
