(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...
Discuss the similarities and differences between DNA replication and RNA transcription. Briefly describe the process of DNA replication in lagging strand and why the process is different compare to the replication process in leading strand? Explain DNA replication in the lagging...

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,...
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...
. 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 ...
The template for RNA polymerase III in vitro transcription found on the human DNA clone pJP53 was shown in the previous paper to enclose a member of the Alu famiy of interspersed repetitive DNA sequences. We have mapped this transcript onto its template in greater detail by comparison of the...
How is base pairing involved in DNA replication? What are some similarities between transcription and DNA replication? What is the difference between transcription and DNA replication? Where does DNA replication begin? What are primers in DNA replication?
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?
