Which of the following statements concerning RNA transcription is/are FALSE? Choose all that apply.

a. Transcription requires the use ofa primer.

b. Four ribonucleotides (rNTPs) types are required

c. The release of pyrophosphate from a nucleotide triphosphate supplies energy for the elongation reaction.

d. The template strand is read in the 3' to 5" direction.

e. RNA polymerase reads and copies both DNA strands at it moves along the double helix.

f. Base pairing from DNA to RNA includes the pairs of A to U and C to G

The correct answer will be options - A and E

Explanation:

Transcription is a process which produces the copy or transcript of the DNA molecule called mRNA or messenger RNA.

The transcription process proceeds in three steps: initiation, elongation and termination. The process is mediated by the enzyme RNA polymerase which adds complementary nucleotides to the RNA through energy-dependent process gaining energy from the pyrophosphate or two bonded phosphate groups.

The RNA polymerase runs in the direction of 3' TO 5' polarity adding nucleotides to 3' - OH groups on one strand. The base pairing occurs between four different bases that are adenine will bind to uracil instead of thymine and cytosine will bind to guanine through three hydrogen bonds.

Thus, the selected options are the correct answer.
