Overview of Transcription
Multiple Choice
In the overview of transcription, DNA is used as a template for making which type of molecule?
A
DNA (a daughter DNA strand during replication)
B
A polypeptide (protein) directly
C
ATP (adenosine triphosphate)
D
RNA (a transcript such as mRNA)
Verified step by step guidance1
Understand the process of transcription, which is the first step in gene expression where a segment of DNA is copied into RNA by the enzyme RNA polymerase.
Recognize that during transcription, the DNA sequence of a gene is used as a template to synthesize a complementary RNA strand, not DNA or protein directly.
Recall that the RNA produced can be messenger RNA (mRNA), which carries the genetic information from DNA to the ribosome for protein synthesis.
Note that ATP is a molecule used for energy transfer in cells and is not directly produced by transcription.
Conclude that the correct molecule synthesized during transcription is RNA, specifically types like mRNA, tRNA, or rRNA, depending on the gene being transcribed.
