What would be the result of a cytosine base being substituted for a thymine base in a DNA segment during DNA replication?
(1 point)

O There would be no effect on the DNA.
O The cytosine base would pair with adenine when the DNA was replicated
O The sequence could code for the wrong amino acid during translation
O The entire segment of DNA would be affected.

If a cytosine base is substituted for by a thymine base in a DNA segment during DNA replication, the sequence could code for the wrong amino acid during translation.

The change in the sequence of DNA is known as mutation.

When a base substitution occurs in the sequence of a DNA during replication, the genetic information in the region where the substitution occurred becomes compromised.

During transcription, the process of encoding genetic information on DNA into RNA, the base substituted is also transcribed along. If cytosine is substituted by thymine, adenine is transcribed instead of guanine.

During the translation of the genetic codes, the wrong amino acids might end up being translated due to the substituted base, leading to a faulty protein.
