Question

Look at the diagram of DNA below. Which of the following parts of the diagram represents the hydrogen bond that holds the two strands of DNA together?

[Key: yellow-A, green-T, red-G, blue-C]

Answer 1

Y represents hydrogen bonding

Answer 2

Answer;

Y-represents hydrogen bond

Explanation;

• DNA is a type of nucleic acid, that carries genetic information in organisms. DNA is made up of nucleotide bases; guanine, Cytosine, Adenine,l and Thymine, which are the building blocks of nucleic acids.
• Complementary base pairs of guanine with cytosine and adenine with Thymine between the DNA strands connect to each other using hydrogen bonds.
• Hydrogen bonds between the complementary nucleotides keeps the two strands of DNA helix together.
