Question

Which best supports the choice from the previous question?

Responses

A. Deletion mutations occur during protein synthesis, changing the order of polypeptides.

Deletion mutations occur during DNA replication, not protein synthesis

A. Deletion mutations occur during protein synthesis, changing the order of polypeptides. Deletion mutations occur during DNA replication, not protein synthesis

B.

Deletion mutations occur after DNA replication, changing how mRNA is translated.

Deletion mutations occur during, not after, DNA replication.

B. Deletion mutations occur after DNA replication, changing how mRNA is translated. Deletion mutations occur during, not after, DNA replication.

C.

Deletion mutations occur during DNA replication, changing how DNA is transcribed.

Deletion mutations occur when part of a DNA molecule is not copied properly during DNA replication. This leads to errors in the consecutive processes of transcription and translation.

C. Deletion mutations occur during DNA replication, changing how DNA is transcribed. Deletion mutations occur when part of a DNA molecule is not copied properly during DNA replication. This leads to errors in the consecutive processes of transcription and translation.

D. Deletion mutations occur after protein synthesis, changing the proteins that are formed.

Deletion mutations occur during DNA replication, not after protein synthesis

Answer 1

C.

It correctly states that deletion mutations occur during DNA replication and explains how a missing DNA segment leads to errors in transcription and translation. The other choices are wrong about the timing (they say protein synthesis or after replication).
