Question

One strand of DNA nucleotides is read as 5' - GCATATTG - 3'. What would

be the complementary strand?

Answer 1

The correct answer would be: 3' - CGTATAAC - 5'

Step-by-step explanation:

DNA molecule is a double-stranded molecule structure that has two distinct nucleotide chains joined together with hydrogen bonds between the nitrogenous bases of each strand. Adenine binds with thymine and cytosine binds with guanine by hydrogen bonds always in complementary strands.

These strands are complementary to one another as they have complementary bases in the complementary strand of one nucleotide chain of DNA. So,

5' - GCATATTG - 3' - DNA nucleotide of one strand

3' - CGTATAAC - 5' complementary strand
