WebDistinguish between 1. unidirectional and bidirectional synthesis and 2. continuous and discontinuous synthesis of DNA unidirectional means only one way polymerization after synthesis while bidirectional means boths ways with some discontinuous synthesis List the proteins that unwind DNA during in vivo DNA synthesis. How do they function? WebWhich statement about DNA replication is true?1) DNA synthesis of the leading strand is discontinuous because DNA polymerase can only synthesize DNA in 5'-to-3' …
WebSep 27, 2024 · DNA replication is catalyzed by a group of enzymes known as DNA polymerases. DNA replication proceeds in a semi-discontinuous manner, meaning that the two strands of DNA are replicated in separate, discontinuous segments. The leading strand, which is replicated in a continuous manner, is synthesized by DNA polymerase in … Websynthesis leading strand The opposite strand undergoes discontinuous synthesis from BIOLOGY 5667 at Niceville Senior High School
WebWe mentioned above that replication is continuous on one strand (see fig. 6.32 part e) and discontinuous on the other. One must continue to unwind the two strands of the DNA from one another and hence the presence of a DNA helicase is necessary (see fig. 6.32, part a). WebJul 19, 2024 · The conversion of single‑stranded phage DNA to duplex DNA occurs by the synthesis of several Okazaki fragments, and hence it is a good model for …
WebSynthesis of the lagging strand proceeds not continuously, as on the leading strand, but discontinuously in a series of repeated steps. Discontinuous replication produces a …
