Protein Synthesis

Question 2 • First Semester Biology

Which process is part of transcription?

Answer
A
DNA is copied to create a second DNA strand.
B
mRNA codons and tRNA anticodons assemble amino acids.
C
DNA is unzipped with the aid of DNA polymerase.
D
mRNA is synthesized from a strand of DNA.

Explanation

Transcription is the process of making an RNA copy of a gene using DNA as a template. Therefore, mRNA is synthesized from a strand of DNA, which is choice D. Choice B describes translation, when codons and anticodons help assemble amino acids into a protein.
