Question

how could a deletion error occur during dna replication?
a. rna primers are removed from the growing strand.
b. hydrogen bonds are unable to form between base pairs.
c. one or more nucleotides are removed from the old strand.
d. one or more nucleotides are omitted from the new strand.

Explanation:

A deletion error in DNA replication occurs when nucleotides are left out during the synthesis of the new strand. RNA primers being removed (A) is a normal part of DNA replication. Hydrogen bonds not forming (B) would disrupt base - pairing but not specifically cause a deletion. Removing nucleotides from the old strand (C) is not relevant to a deletion error in the new strand. Omitting nucleotides from the new strand (D) directly causes a deletion.

Answer:

D. One or more nucleotides are omitted from the new strand.
