Question

When DNA is copied, sometimes a new, incorrect, base pairing appears within the structure of a new DNA molecule replacing original base pairs. This mistake is called a base-pair
a. deletion
b. institution
c. Substitution

Answer 1

Answer: The correct answer is C) Substitution.

Substitution is a type mutation ( permanent change in the genetic material of the organism) that is caused by the exchange of one base with another.

This can occur during the process of DNA replication when an incorrect base is added in the new DNA molecule and thus replacing the original base pair. This can result in formation of new amino acid ( that result in different protein) or it may form a truncated protein ( when stop codon is produced due to substitution).

Answer 2

It would be substitution because an incorrect base pair is being replaced.
