What is the need for a primer in transcription? Group of answer choices It ensures the fidelity of the newly synthesized RNA strand. RNA polymerases requires a preexisting strand with a nucleotide having a 3'−OH. RNA polymerase requires a preexisting strand with a nucleotide having a 5'−OH. There is none.

Respuesta :

Answer:

There is none.

Explanation:

DNA polimerase needs a preexisting 3'−OH to start building a DNA strain, and that´s why in DNA replication a primer made of RNA is needed to start the process.

RNA polimerase does not need a 3'−OH to start building a RNA strain. It attaches and moves along the DNA adding ribonucleotides in the growing RNA chain.
