When adenine replaces guanine because of a mutation, what name is that mutation given?
Correct answer: C. Transition
- A. Frame shift mutation
- B. Transcription
- C. Transition
- D. Transversion
Explanation
When adenine replaces guanine because of a mutation, it is called a transition. Transitions are the most common type of mutation, and they occur when one purine base (adenine or guanine) is replaced by another purine base. Other options are incorrect because:Transversions are less common, and they occur when a purine base is replaced by a pyrimidine base (cytosine or thymine), or vice versa.Frame shift mutations occur when a base is inserted or deleted from the DNA sequence. This can cause the reading frame of the DNA to shift, which can lead to the production of a non-functional protein.Transcription is the process of copying DNA into RNA. It is not a type of mutation.

About Chromosomes
Chromosomes are DNA-protein structures that carry genes and become visible during cell division. Coverage includes chromatin, centromeres, sister chromatids, homologous chromosomes, chromosome number, and the distinction between diploid and haploid cells, with links to DNA replication, mitosis and meiosis.
