Question
Hemoglobin, a protein found in red blood cells, carries oxygen. Abnormal hemoglobin cannot carry as much oxygen as normal hemoglobin. The sequences below show the sections of the DNA sequence that produce both the normal and abnormal types of hemoglobin.

Which statement is the BEST explanation for what caused the formation of the abnormal hemoglobin protein?
A.
After transcription, a mutation happened in the messenger RNA sequence that then caused the translation of the messenger RNA to produce the abnormal hemoglobin protein.
B.
A mutation in the translation of the DNA sequence caused the mesenger RNA to transcribe the wrong sequence causing the development of the abnormal hemoglobin protein.
C.
A mutation occurred in the DNA sequence that was then transcribed by the messenger RNA and caused the translation of the messenger RNA to produce the abnormal hemoglobin protein.
D.
After translation, a mutation happened in the messenger RNA sequence that caused the DNA section of the gene to change, resulting in the formation of the abnormal hemoglobin protein.

The BEST explanation for the formation of the abnormal hemoglobin protein is:
**C. A mutation occurred in the DNA sequence that was then transcribed by the messenger RNA and caused the translation of the messenger RNA to produce the abnormal hemoglobin protein.**
This option correctly describes the process of mutation in the DNA leading to changes in the mRNA during transcription, which then results in the production of an abnormal protein during translation.
**C. A mutation occurred in the DNA sequence that was then transcribed by the messenger RNA and caused the translation of the messenger RNA to produce the abnormal hemoglobin protein.**
This option correctly describes the process of mutation in the DNA leading to changes in the mRNA during transcription, which then results in the production of an abnormal protein during translation.
