Dna polimerasa 3
WebLa transcripción es el proceso en el que la secuencia de ADN de un gen se copia (transcribe) para hacer una molécula de ARN. La ARN polimerasa es la principal … WebDNA polymerase cannot initiate new strands of nucleic acid synthesis because it can only add a nucleotide onto a pre-existing 3′-OH. Therefore, an 11 to 12 base-pair length of RNA (an RNA primer) is made at the beginning of each new strand of DNA. Since the leading strand is synthesized as a single piece, there is only one RNA primer at the origin.
