WebThe process of DNA replication can be summarized as follows: DNA unwinds at the origin of replication. Helicase opens up the DNA-forming replication forks; these are extended in both directions. Single-strand … WebInitiation of eukaryotic DNA replication is the first stage of DNA synthesis where the DNA double helix is unwound and an initial priming event by DNA polymerase α occurs on the leading strand. The priming event on the … WebIn eukaryotes, the low-processivity enzyme, Pol α, helps to initiate replication because it forms a complex with primase.

WebKey points: DNA replication is semiconservative. Each strand in the double helix acts as a template for synthesis of a new, complementary strand. New DNA is made by enzymes called DNA polymerases, which require a template and a primer (starter) and synthesize … The replication fork is the branched (forked) DNA at either end of the replication … WebOverview of the Stages of Transcription. The basic steps of transcription are initiation, elongation, and termination. Here we can identify several of the DNA sequences that characterize a gene. The promoter is the binding site for RNA polymerase. It usually lies 5’ to, or upstream of the transcription start site.
