Helicase – The point at which the replication begins is known as the Origin of Replication. Helicase brings about the procedure of strand separation, which leads to the formation of the replication fork. It breaks the hydrogen bond between the base pairs to separate the strand. It uses ene...

Despite the dense packing of DNA in chromosomes, it must be accessible to regulatory proteins during replication and gene expression. At a higher level of organization, chromosomes are divided into regions called euchromatin and heterochromatin. Transcription of genes seems to be confined to euchromatin...

During DNA replication, each of the two strands that make up the double helix serves as a template from which new strands are copied. The new strand will be complementary to the parental or “old” strand. When two daughter DNA copies are formed, they have the same sequence and are divide...
3月6日,香港大学翟元梁教授、北京大学高宁教授和李晴教授及康奈尔大学戴碧瓘教授合作,在Nature杂志发表题为“Parental histone transfer caught at the replication fork”的研究论文。该研究利用酵母纯化的内源性复制体样品,成功捕捉到DNA...
In eukaryotes, a dedicated replisome removal pathway has recently been identified, which operates late during termination, after the DNA is fully replicated. It is unclear whether any comparable pathway exists in bacteria.Abstract Genome duplication is carried out by pairs of replication forks that ass...
