During the process in which free RNA nucleotides pair with complementary DNA nucleotides on one strand of DNA, which cellular process is occurring?
A
Translation
B
Transcription
C
Replication
D
Reverse transcription
Verified step by step guidance1
Identify the key components involved in the process: free RNA nucleotides and a DNA strand.
Recall that when RNA nucleotides pair with a DNA strand, the process is synthesizing RNA from a DNA template.
Understand that this process is called transcription, where the enzyme RNA polymerase facilitates the formation of an RNA strand complementary to the DNA template strand.
Differentiate transcription from other processes: replication involves DNA synthesis, translation involves protein synthesis from mRNA, and reverse transcription involves synthesizing DNA from RNA.
Conclude that the described process, pairing free RNA nucleotides with DNA, corresponds to transcription.
