10.3真核生物DNA复制过程 DNA replication in prokaryotes(上)。听TED演讲,看国内、国际名校好课,就在网易公开课
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 ......
Describe the manner in which the DNA can be transferred from one cell to another by explaining and describing the following mechanisms in prokaryotes: transformation, conjugation, and transduction. Explain what is involved in DNA replication. List three main steps in the process of DNA replication....
These are equivalent to the origin of replication in E. coli. The number of DNA polymerases in eukaryotes is much more than in prokaryotes: 14 are known, of which five are known to have major roles during replication and have been well studied. They are known as pol α, pol β, pol ...

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 ...
theorigin of replication, where various proteins bind to begin the replication process.E. colihas a single origin of replication (as do most prokaryotes), calledoriC, on its one chromosome. The origin of replication is approximately 245 base pairs long and is rich in adenine-thymine (AT) ...
