DNA polymerase is the enzyme that replicates DNA by adding new nucleotides to the 3′ end of a growing strand. Main Menu. Hence, DNA polymerase moves along the template strand in a 3'–5' direction, and the daughter strand is formed in a 5'–3' direction. Okazaki fragments bound by ligase. This technique, called the polymerase chain reaction (PCR), is far easier than traditional molecular cloning methods, and it has become a staple of many laboratories in the life sciences. Builds DNA in the 5' 3' direction. D.DNA polymerase I synthesizes DNA in the 5׳ to 3׳ direction and DNA polymerase III synthesizes on lagging strands. This is the phase where the DNA polymerase grows the new DNA daughter strand by attaching to the original unzipped template strand and the initiating short RNA primer. C.DNA polymerase I repairs DNA and DNA polymerase III synthesizes DNA in the 3׳ to 5׳ direction. 2007-08-07T02:04:54Z Madprime 700x1400 (342394 Bytes) {{Information |Description=Diagram of DNA polymerase extending a DNA strand and proof-reading. Lakhmir Singh Class 10 Solutions; NCERT Solutions Menu Toggle. • RNA polymerase is capable of fulfilling many more functions compared to what DNA polymerase could do. Because PCR involves repeated cycles of heating and cooling, we’ll need DNA polymerase that won’t become denatured at high temperatures. Most of the people.
