The Process of ________ Requires the Activity of DNA Ligase

Question

The process of ________ requires the activity of DNA ligase.
A) translation
B) capping
C) transcription
D) DNA replication
E) transduction

Accepted Answer

DNA replication is the process of copying DNA. DNA ligase is an enzyme that seals the gaps between the Okazaki fragments on the lagging strand during DNA replication. Therefore, the correct answer is D. Translation is the process of synthesizing proteins from mRNA, capping is the addition of a 5' cap to an mRNA molecule, transcription is the process of synthesizing RNA from DNA, and transduction is the transfer of genetic material from one cell to another via a virus. These processes do not require the activity of DNA ligase.
