Lesson 3: Protein Synthesis

Question 15 • CA-Biology A-CR

Which statement best summarizes what happens during transcription?

Answer
A
A DNA template is used to create an mRNA strand.
B
An mRNA template is used to create a DNA strand.
C
A DNA template is used to create a ribosome.
D
An mRNA template is used to create a tRNA strand.

Explanation

During transcription, RNA polymerase reads a DNA template and builds a complementary RNA strand, usually mRNA. The statement “A DNA template is used to create an mRNA strand” describes this process. Using mRNA to make a protein happens later, during translation.
