Question
Chapter 24, Problem 66A
Interpretation Introduction
Interpretation: The type of bonding that helps to hold a DNA double helix together is to be explained.
Concept introduction: Deoxyribonucleic acid (DNA) is made of two polynucleotide chains forming a double helix around each other. Adenine (A), cytosine (C), guanine (G), and thymine (T) are the four nitrogen-containing base pairs that make up a DNA molecule. The bases adenine and thymine and cytosine and guanine form complementary pairs.
Expert Solution & Answer
Answer to Problem 66A
The two strands of DNA that make up a double helix are held together by hydrogen bonding.
Explanation of Solution
The structure of DNA is formed by the pairing and binding of the base pairs.
The DNA double helix is shown as follows:
Hydrogen bonds formed between nitrogen bases on opposite strands of a DNA double helix are responsible for keeping the two strands of the molecule together.
The hydrogen bonding between base pairs is shown as follows:
Conclusion
The two strands of DNA that make up a double helix are held together by hydrogen bonding.
