Dna after replication
WebWhat is the function of DNA polymerase? A) to unwind the DNA helix during replication B) to seal together the broken ends of DNA strands C) to add nucleotides to the end of a growing DNA strand D) to degrade damaged DNA molecules E) to rejoin the two DNA strands (one new and one old) after replication C WebDNA is a long polymer made from repeating units called nucleotides. The structure of DNA is dynamic along its length, being capable of coiling into tight loops and other shapes. In all species it is composed of two helical chains, bound to each other by hydrogen bonds.Both chains are coiled around the same axis, and have the same pitch of 34 ångströms (3.4 nm).

WebChandré Liebenberg April 2024 The proteins that initially bind to ori sites to recruit the other enzymes needed for DNA replication (to eventually form the replicon) have the ability to remodel DNA by consuming ATP. DnaA in E.coli is such a molecule that promotes the initial separation of strands (it is a replication initiator) at a specific, easy-to-melt site in the ori, … WebOct 29, 2024 · Both the incapacity of the immune system to clear hepatitis B virus (HBV) infection and the unique replication strategies adopted by HBV are considered key …

WebJun 8, 2024 · After DNA replication, each newly synthesized DNA strand is shorter at its 5′ end than at the parental DNA strand’s 5′ end. This produces a 3′ overhang at one end (and one end only) of each daughter DNA strand, such that the two daughter DNAs have their 3′ overhangs at opposite ends.
