Which of the following best describes the primary function of the enzyme integrase?
A
It phosphorylates glucose to form glucose-6-phosphate.
B
It cleaves peptide bonds in proteins.
C
It synthesizes RNA from a DNA template.
D
It incorporates viral DNA into the host genome.
Verified step by step guidance1
Understand the role of integrase: Integrase is an enzyme primarily associated with retroviruses, such as HIV. Its main function is to facilitate the integration of viral DNA into the host cell's genome.
Eliminate incorrect options: Review the provided options and compare them to the known function of integrase. For example, phosphorylation of glucose to form glucose-6-phosphate is performed by hexokinase, not integrase.
Consider peptide bond cleavage: Cleaving peptide bonds in proteins is a function of proteases, not integrase. This option can also be eliminated.
Evaluate RNA synthesis: Synthesizing RNA from a DNA template is the role of RNA polymerase, not integrase. This option is unrelated to the enzyme's function.
Confirm the correct answer: The correct description of integrase's primary function is its ability to incorporate viral DNA into the host genome, enabling the virus to hijack the host's cellular machinery for replication.
