during dna replication, a thymine base is removed from the dna. what type of mutation is this? a. point mutation b. missense mutation c. nondisjunction mutation d. frameshift mutation

Answer

Brief Explanations:

A point mutation involves a change in a single - base pair. A missense mutation is a type of point mutation where a single - base change results in a different amino acid. Nondisjunction is related to the improper separation of chromosomes during cell division. When a base is removed from DNA during replication, it shifts the reading frame of the genetic code for all subsequent bases. This is a frameshift mutation.

Answer:

D. Frameshift mutation
