Web16 jan. 2024 · For Taq DNA polymerase, the KM s of the dNDP and phosphate substrates are ∼20 and 200 times higher than for dNTP and pyrophosphate, respectively. DNA synthesis from dNDPs is about 17 times slower than from dNTPs, and DNA phosphorolysis about 200 times less efficient than pyrophosphorolysis. WebExpert Answer. 100% (35 ratings) Transcribed image text: Replication can proceed in opposite directions from the same origin of replication. This is called bidirectional synthesis.

Web6 jul. 2024 · 2.2) Why does DNA synthesis only proceed in the 5’ to 3’ direction? Because DNA polymerase can only add nucleotides to the 3´ end of the polynucleotide strand. Because the 3´ end of the polynucleotide molecule is more electronegative that the 5´ end. Because that is the direction in which the two strands of DNA unzip. WebIf Dna pol could do synthesis of both strand continously then both strands would have been replicated in the opposite direction as it can act only from 5 ' to 3' direction. WebHowever, DNA polymerase enzymes are only able to synthesize DNA in the 5′ 3′ direction. This means that one strand of the parent double helix, called the leading strand, can be copied out in a continuous manner, but replication of the lagging strand has to be carried out in a discontinuous fashion, resulting in a series of short segments that must be ligated … granini selection cranberry
