C banding

C banding

(Science: molecular biology) method of defining chromosome structure by staining with giemsa and looking at the banding pattern in the heterochromatin of the centromeric regions. Giemsa banding (g banding) of the whole chromosome gives higher resolution. Q banding is done with quinacrine.

Re: Codons are triplets, but what's a Singlet, Doublet, etc?

... While the GPU technology is coming of age I’m working on the problems that do not require a supercomputer to solve. The chromosome banding program is one of them. It does not need to search for similarity like the BLAST algorithm does, this algorithm just has to most simply dissect ...

Codons are triplets, but what's a Singlet, Doublet, etc?

... program (a simple how-to for programmers and general public) that compares/displays chromosomes, using a technique I called "digital banding".

Re: Basic electrophoresis digest banding pattern analysis....

I'm no mol bio person but why is the uncut control (2nd lane) running as two bands so far apart? Isn't plasmid supposed to run in three bands pretty close to each other? Student A (lane 3) looks as if he has (i) Forgot to add enzyme/added too less. (ii) Added way too much plasmid. The later seems mo...

Advantages of traditional cytogenetics over PCR

What would you define as traditional cytogenetic methods? Are they simply banding techniques, or is there more to it? I can think of plenty of advantages of PCR over this is cytogenetic studies but what are the advantages of ttraditional methods over PCR? Thanks
