Multiple Choice

Which of the following happens during DNA replication?

Messenger RNA is translated into protein.

Chromosomes condense and align at the metaphase plate.

The DNA double helix is unwound and each strand serves as a template for a new complementary strand.

Amino acids are joined together by peptide bonds.

Verified step by step guidance

Understand the process of DNA replication: it involves copying the DNA molecule to produce two identical DNA strands.

Recall that during DNA replication, the DNA double helix unwinds to expose each strand, which then serves as a template for synthesizing a new complementary strand.

Recognize that messenger RNA translation into protein and amino acid joining by peptide bonds are part of protein synthesis, not DNA replication.

Note that chromosome condensation and alignment at the metaphase plate occur during mitosis, not during DNA replication.

Conclude that the correct event during DNA replication is the unwinding of the DNA double helix and the use of each strand as a template for a new complementary strand.
