Which of the following best describes the function of mRNA in the process of transcription?
A
It catalyzes the formation of peptide bonds during translation.
B
It serves as a template for DNA replication.
C
It transports amino acids to the ribosome during translation.
D
It carries the genetic information from DNA to the ribosome for protein synthesis.
Verified step by step guidance1
Understand the role of mRNA in the central dogma of molecular biology, which describes the flow of genetic information from DNA to RNA to protein.
Recall that transcription is the process where a segment of DNA is copied into mRNA by the enzyme RNA polymerase.
Recognize that mRNA carries the genetic code from the DNA in the nucleus to the ribosome in the cytoplasm, where protein synthesis occurs.
Differentiate mRNA from other RNA types: tRNA transports amino acids, and rRNA is part of the ribosome structure; mRNA specifically serves as the messenger carrying the instructions.
Conclude that the function of mRNA in transcription is to carry the genetic information from DNA to the ribosome for protein synthesis.
