during DNA replication process, a cytosine base is replaced by a thymine base- what is the result and what type of mutation occurs?

Question

wrong amino acid is produced and attached to a protein resulting in an insertion mutation
wrong amino acid is produced and attached to a protein resulting in a substitution mutation
wrong amino acid is produced and attached to a protein resulting in a deletion mutation
wrong amino acid is produced and attached to a protein resulting in an inversion mutation

Answer 1

When a cytosine base is replaced by a thymine base during the DNA replication process, this change results in a substitution mutation. This is because one base is exchanged for another, which can lead to a change in the sequence of nucleotides and potentially affect the corresponding codon during translation.

In this scenario, if the change leads to the incorporation of a wrong amino acid in the resulting protein, we specifically refer to it as a substitution mutation. Therefore, the correct statement is:

wrong amino acid is produced and attached to a protein resulting in a substitution mutation.
