In what way does RNA polymerase differ from DNA polymerase?
A
RNA polymerase synthesizes RNA, while DNA polymerase synthesizes DNA.
B
RNA polymerase requires a primer to initiate synthesis, while DNA polymerase does not.
C
RNA polymerase is involved in DNA replication, while DNA polymerase is involved in transcription.
D
RNA polymerase works only in the nucleus, while DNA polymerase works in the cytoplasm.
Verified step by step guidance1
Understand the roles of RNA polymerase and DNA polymerase: RNA polymerase is responsible for synthesizing RNA from a DNA template during transcription, while DNA polymerase synthesizes DNA during DNA replication.
Clarify the requirement for a primer: DNA polymerase requires a primer to initiate DNA synthesis, whereas RNA polymerase does not need a primer to start RNA synthesis.
Identify the processes each enzyme is involved in: RNA polymerase is involved in transcription, the process of copying a segment of DNA into RNA. DNA polymerase is involved in DNA replication, the process of making a copy of the entire DNA molecule.
Consider the location of activity: RNA polymerase primarily functions in the nucleus where transcription occurs, while DNA polymerase also functions in the nucleus during DNA replication.
Review the correct statements: RNA polymerase synthesizes RNA, does not require a primer, and is involved in transcription. DNA polymerase synthesizes DNA, requires a primer, and is involved in replication.
