Now when replication fork moves ahead and the Polymerase III starts to synthesize the new strand a small problem arises. If you remember, I mentioned that the two strands run in the opposite directions. This means that when both strands are being synthesized in 5’ to 3’ direction, one ...
DNA Structure & DNA ReplicationSchematic diagram of DNA replication Table of Contents Previous pages in this tutorial have described the basics of a cell, the energy required by these cells and how energy is created in order for the cell to survive (via respiration and photosynthesis).The...
DNA replication begins with the unwinding of the DNA strands. Through the action of the enzymehelicase, a portion of the helix will “open” as the two strands separate. The point at which the strands separate is referred to as thereplication fork (replication fork is a Y-shaped region in ...
Current temporal studies of DNA replication are either complex or low-resolution. Here, the authors introduce Nanotiming, a simple and inexpensive method producing high-resolution, telomere-to-telomere replication timing profiles through BrdU-mediated capture of dTTP pool expansion in S phase. Bertrand...

We show that totipotent cells of the early mouse embryo have slow DNA replication fork speed and that 2CLCs recapitulate this feature, suggesting that fork speed underlies the transition to a totipotent-like state. 2CLCs emerge concomitant with DNA replication and display changes in replication ...
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...
The adenoviral life cycle centers around a burst of viral replication that ultimately results in host cell lysis. Methods to minimize the production of cytotoxic adenoviral proteins are still being sought. Unlike the case for retrovirus, the large size of the adenoviral genome as well as the ...
Thus, we propose that replication-incompetent nucleoids are selectively eliminated by an adaptive mitochondria–endosomal quality control pathway that is prone to innate immune system activation, which might represent a therapeutic target to prevent mtDNA-mediated inflammation during viral infection and ...
