In the present study, we employed DNA fiber analysis to investigate how pluripotent stem cells are reprogrammed into totipotent-like 2-cell-like cells (2CLCs). We show that totipotent cells of the early mouse embryo have slow DNA replication fork speed and that 2CLCs recapitulate this feature,...

There are three steps in the process of generating a protein from the information stored within DNA: transcription, RNA processing, and translation. DNA replication occurs in the nucleus because DNA is located in the nucleus, and transcription, the process of creating a temporary RNA copy of the...
(a)Compare between DNA replication and transcription.Similarities1. Both involve unwinding of the double helix DNA;2.Both involve breaking of the weak hydrogen bonds between complementarbases;3.Both involve formation of phosphodiester bonds between neighbouring nucleotides;4.Both involve aligning free nucl...

including DNA replication,transcription,and translation,share strong similarities with those of Eukaryota.Therefore,archaea provide useful model systems to understand the more complex mechanisms of genetic information processing in eukaryotic cells.Moreover,the hyperthermophilic archaea provide very stable ...
Accurate chromosomal DNA replication is essential to maintain genomic stability. Genetic evidence suggests that certain repetitive sequences impair replication, yet the underlying mechanism is poorly defined. Replication could be directly inhibited by the DNA template or indirectly, for example by DNA-bound...
How does RNA polymerase know which strand of DNA to use as template? What is the function of topoisomerase in DNA replication? When does DNA replication occur? How does DNA control the structure of proteins? What are some similarities between transcription and DNA replication?
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 calledeuchromatinandheterochromatin. Transcription of genes seems to be confined to euchromatin ...
