Q. The number of hydrogen bonds formed between in the sequence of a stretch of a double helical DNA $5’ATGCCTAA3’$ is

Biomolecules

Solution:

The number of hydrogen bonds present in the sequence of a stretch of a double helical DNA $5'$ ATGCCTAA $3'$ is 19 . A always combines with T by two hydrogen bonds and $G$ combines with $C$ by three hydrogen bonds. Thus, we can simply sum them up to get the required result.
