Question

.Transcription requires


a.DNA, ribonucleotides and RNA polymerase

b.DNA, deoxyribonucleotides and RNA polymerase

c.DNA, deoxyribonucleotides and DNA polymerase

d.RNA, ribonucleotides and DNA polymerase​

Answer 1

Answer:   Transcription requires the DNA double helix to partially unwind such that one strand can be used as the template for RNA synthesis. The region of unwinding is called a transcription bubble.

Explanation:

Abstract. Primer RNA is RNA that initiates DNA synthesis. Primers are required for DNA synthesis because no known DNA polymerase is able to initiate polynucleotide synthesis. Edited transcriptional RNA is used to initiate DNA synthesis in some phage and in metazoan mitochondria

RNA polymerase is an enzyme that is responsible for copying a DNA sequence into an RNA sequence, duyring the process of transcription.

To synthesize the two chains of deoxyribonucleotides during DNA replication, the DNA polymerase enzymes involved are only able to join the phosphate group at the 5' carbon of a new nucleotide to the hydroxyl (OH) group of the 3' carbon of a nucleotide already in the chain.

Missing   (A) Incorporation and removal of ribonucleotides incorporated by RNA primase during OF synthesis and maturation. ... The polymerase exonuclease activity can excise ribonucleotides from the 3′ terminus in primer-template DNA, an event that is more efficient on a mismatched 3′ terminal dNMP primer than it is on an rNMP.
