Question

Transcription occurs along a ____ template forming an mRNA in the ____ direction. (0.5 pts.) A) 5' to 3'; 5' to 3' B) 5' to 3'; 3' to 5' C) 3' to 5'; 5' to 3' D) 3' to 5'; 3' to 5'

Answer 1

Answer:

3' to 5'; 5' to 3'

Explanation:

The DNA strand with 3' to 5' polarity serves as a template for the process of transcription. Using the 3' to 5' DNA template strand, the enzyme RNA polymerase catalyzes the formation of RNA.  The ribonucleotides are bonded together by phosphodiester bonds that are formed in 5' to 3' direction only. The formation of RNA occurs in 5' to 3' direction. The DNA template strand has a complementary nucleotide sequence to the newly synthesized RNA.

Answer 2

Answer: Option C.

Transcription occur along 3' to 5' and direction 5' to 3'.

Explanation:

Transcription is a process where a DNA gene sequence is been copied to an RNA sequence by an enzyme RNA polymerase. During transcription the DNA serve as a template complementary base pairing along 3' to 5' to make RNA molecule where RNA polymerase 11 catalyse the formation of mRNA at 5' to 3' direction.
