In What Direction is an MRNA Molecule Synthesized

Question

In what direction is an mRNA molecule synthesized?
A)3' to 5' direction
B)5' to 3' direction
C)N-terminal to C-terminal direction
D)C-terminal to N-terminal direction
E)N-terminal to 3' direction

Accepted Answer

mRNA is synthesized in the 5' to 3' direction, meaning that nucleotides are added to the 3' end of the growing mRNA strand. The template strand of DNA is read in the 3' to 5' direction, and mRNA is synthesized in the complementary 5' to 3' direction.
