Chapter 9: Problem 9

What is meant by the term DNA sequence?

Short Answer

Expert verified
A DNA sequence is a specific ordering of the nucleotides - adenine (A), guanine (G), cytosine (C), thymine (T) - along the DNA strand, forming a unique code that carries biological instructions used in cell functioning and development.

Step by step solution

01

Define DNA

DNA, or Deoxyribonucleic acid, is a molecule that carries most of the genetic instructions used in the growth, development, functioning, and reproduction of all known living organisms and many viruses.
02

Explain Genetic Code

DNA is composed of four types of nucleotides, which are the building blocks of DNA. These are adenine (A), guanine (G), cytosine (C), and thymine (T). These letters also stand for the four different types of chemicals that make up the DNA molecule.
03

Define DNA Sequence

A DNA sequence is a specific order of these nucleotides along the DNA strand. It's like a unique code that carries biological instructions. This sequence provides detailed instructions to the cell about the production of specific proteins which is essential for the organism's function and development.
