Answer/Explanation:
EGFR stands for epidermal growth factor receptor. It is a transmembrane protein acting as a tyrosine kinase receptor for epidermal growth factor ligands, which are associated with promoting cell division and proliferation. When epidermal growth factor binds to the receptor, it becomes activated and undergoes dimerization and autophosphorylation.
A mutation could occur making the receptor overactive. That is, it does not require ligand binding to become activated, meaning it is always in an "on" state. This would lead to uncontrolled proliferation, a hallmark of cancer.
Answer:
A. Yes, because an amino acid change has occurred.
Explanation:
The sequence given states that the codon CCG is changed to CAG. According to the codon table (attached), CCG codes for <u>proline</u> whereas CAG codes for <u>Glutamine</u>. Therefore, change in mutation has resulted into the change in amino acid. This would lead to the formation of a different protein.
