WebSolution. The correct option is D. All the above. During DNA replication, both the strands of the parental DNA double helix serve as templates. A template strand is simply the strand from which a new complementary strand is synthesised. Complementary to the 3' → 5’ template, the leading strand is synthesised along the 5' → 3’ direction.

WebDNA Replication. Each strand of the DNA copies during replication of the DNA leading to the formation of a daughter DNA double helix. It contains one parental DNA strand and one newly synthesized DNA strand. There is a possibility at this juncture for any change in the sequence of the nitrogen base to take place, in short mutation to occur. WebReplication of DNA is initiated with the introduction of the RNA primer via primase enzyme. Primer’s 3′ end is used as the initial point to add nucleotides by the DNA polymerase at the leading strand. The process terminates at the lagging strand through the synthesis of the Okazaki fragments.

WebDNA Replication It is a biological process by which an original DNA replicates itself to produce two similar copies. It is seen as an essential DNA repair mechanism. Here, the DNA strands separate using the helicase enzyme. The separated DNA acts as a template for the new copies. The three types of DNA replication are – Conservative replication WebPCR or Polymerase Chain Reaction is a technique used in molecular biology to create several copies of a certain DNA segment. This technique was developed in 1983 by Kary Mullis, an American biochemist. PCR has made it possible to generate millions of copies of a small segment of DNA.
WebRNA primers are key to initiating DNA synthesis. They provide the initiation sequence necessary for DNA polymerase to synthesize new strands. The RNA primer is introduced at the template DNA site by primase enzyme on both the leading and lagging strands. The 3'-OH free end of the primer is utilized by the polymerase enzyme to extend the growing ...

During the process of replication the double stranded DNA is separated from each other by the help of enzymes like topoisomerases and helicases. cyberverse acid stormWebReplication is the process of doubling the DNA strands. The DNA strands are wound helically, therefore it is a separate task to process the strands for replication. The enzyme helicase is responsible for this separation.
