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.

Re: Chromatin

Before replication there were 23 pairs of molecules, 23 of maternal origin and 23 of paternal origin, ... 46 centromeres total. After replication there are still 46 centromeres, but the mass of DNA and number of chromatids have doubled (and so you get the X-shaped chromosomes you typically ...

No "beginning-replication problem" on leading strand?

... the extreme end have a RNA primer to make the last Okazaki fragment, and after the removal of this primer it needs to somehow be replaced with DNA. I have the latest version of Molecular Biology of the Gene book (by Watson) in front of me and that's the only explanation provided. However, what ...
