counting base pairs

Dear all,

how to count the base pairs of a DNA and protein sequence?
What are the codings in VB?

Thread moved from the 'CodeBank VB6' forum (which is for you to post working code examples, not questions) to the 'VB6 and earlier' forum

How does a protein sequence (your data) look like?

I'm no biologist, I've just had a quick peek at wikipedia, do you have a bunch of strings which you need to match up like "(5)ATCGATTGAGCTCTAGCG(3)" pairs with "(5)CGCTAGAGCTCAATCGAT(3)" (I think I've just twigged where the film GATTACA gets its name.)

Sorry about the non-related posts that you might have seen before I deleted them.

OK, on the assumption that this is a serious question, and taking baja_yu's question into account, what data do you have (an example would be helpful) and what code have you already tried ?

I've done some research and I suspect you've just worded your request slightly incorrectly.

Are you looking to take a protein, work out the amino acids and RNA / DNA condons, and then decode into nucleotides and count them ?

eg (Somewhat simplified)
Peptide -> amino acids = Met Alo Trp Thr Ser -> mRNA = A U G G C C U G G A C U U C A
-> DNA Condons(Antisense) = {T A C} {C G G} {T C C} {T G T} {T G T}
-> nucleotides = T A C C G G T C C T G T T G T
from which you can work out the Sense strand (the Compliment) giving you the Base Pairings
T A C C G G T C C T G T T G T -> Antisense
A T G G C C A G G A C A A C A -> Sense
ie 15 Base Pairs in this example.

EDIT: Further reading suggests (to me at least) that the number of DNA Base Parings will always be 3 X number of amino acids (Number of condons). RNA might be different due to the start and stop condons but I've still to get my head round that.
