Question

The template strand is always:

Select one:

a. translated

b. transcribed in the 5’-3’ direction

c. the coding strand

d. equivalent to the mRNA, with the Thymines replaced with Uracils

e. none of these

Answer 1

b. transcribed in the 5’-3’ direction

Explanation: The template strand is the non coding segment.  Messenger RNA must be made from one strand of DNA called the template strand. The other strand, called the coding strand, matches the messenger RNA in sequence except for its use of uracil in place of thymine.

During transcription, the RNA polymerase read the template DNA strand in the 3′→5′ direction, but the mRNA is formed in the 5′ to 3′ direction.
