Dna replication

Dna replication

(Science: molecular biology) The process whereby a copy of a DNA molecule is made and thus the genetic information it contains is duplicated. The parental double stranded dna molecule is replicated semi conservatively, i.e. Each copy contains one of the original strands paired with a newly synthesised strand that is complementary in terms of AT and GC base pairing. Though in this sense conceptually simple, mechanistically a complex process involving a number of enzymes.

Totipotent Stem Cell From Molecular Components

Q1 I am wanting to make an animal cell from DNA, RNA, Protein, and Fatty Acids as well as Glucose and other sugars. I am wondering. ... or the nucleus and nucleolus(both are very important)? Q2 The pace of DNA replication is 8 2/3 hours for every chromosome and 2097152 of each chromosome in ...

Telomere and DNA replication

After the first division of a particular cell, both daughter cells will contain DNA with one parent strand and one daughter strand 5'_________3'(parent strand - complete telomere) 3'_________5'(daughter stand) The daughter stand is shorter owing to lost telomeres. ...

Protein synthesis during S phase

... protein synthesis during S phase? If it is so, I'd say it's because the DNA is busy with all the replication and thus cannot lose time with transcription.

telomer

If you know the difference between the leading and lagging strand of DNA, one is replicated easily while other lags behind. The long ends of chromosome pose a problem in fidel replication. Telomerase solves the problem to replicate the single ends of the chromosome. ...
