7.2 DNA replication 7.2.1 State that DNA replicationoccursin a 5‘ → 3‘ direction. DNA replication occurs in a 5'→3' direction. 7.2.2 Explain the process of DNA replication in prokaryotes, including the role of enzymes (helicase, DNA polymerase, RNA primase and DNA ligase), Okazaki fra...
DNA Replication: DNA replication is the process in which DNA is copied. DNA replication is a semiconservative process, meaning the parent strand is used as the template strand. Answer and Explanation:1 The steps of DNA replication in prokaryotes is as follows: ...

DNA Replication in Prokaryotes and Eukaryotes DNA replication is a process in which the genetic material of a cell, in this case, the DNA makes an exact copy of itself and the process is controlled by the enzyme DNA polymerase. In mammals, the rate of replication is around 50 nucleotides pe...
replication terminator proteintermination utilisation substancecatenanesMost bacteria and archaea have circular chromosomes, in which DNA replication begins at a site known as an origin of replication. Double﹕tranded DNA unwound at the origin creates two replication forks that are engaged by DNA ...
A common feature of the origins is that they are rich in A = T to facilitate strand separation required for the semiconservative replication. Not uncommonly in the leading strand there is a prevalence of G over C and T over A in prokaryotes an ......

regulation compared to prokaryotes. A single bidirectional replication origin is sufficient to direct all DNA synthesis in prokaryotes. In contrast, eukaryotic chromosome replication requires the orchestration of multiple DNA replication origins to ensure that each DNA polymer, irrespective of its size in ...
