Question

What is the direction of transcription?

A. left to right
B. right to left
C. transcribed from both strands

Answer 1

Transcribed from both strands

Step-by-step explanation:

The direction of transcription is from one of the two strands of DNA to RNA. During transcription, RNA polymerase reads the template DNA strand in the 3’→5’ direction and synthesizes the RNA molecule in the 5’→3’ direction . Therefore, the correct answer is C. transcribed from both strands.

Answer 2

Transcription occurs from the 3' to 5' end of the DNA template strand and results in an RNA molecule synthesized from the 5' to 3' end.

Step-by-step explanation:

The direction of transcription is from the 3' to 5' end of the template strand of DNA to the 5' to 3' end of the resulting RNA molecule.

During transcription, the enzyme RNA polymerase reads nucleotides in a 3' to 5' direction on the DNA template strand and assembles the mRNA transcript in a 5' to 3' direction. The mRNA product is complementary to the template strand of DNA, and the only difference is that T nucleotides are replaced with U nucleotides.
