<P> For case of single - stranded DNA / RNA units of nucleotides are used, abbreviated nt (or knt, Mnt, Gnt), as they are not paired . For distinction between units of computer storage and bases kbp, Mbp, Gbp, etc. may be used for base pairs . </P> <P> The centimorgan is also often used to imply distance along a chromosome, but the number of base pairs it corresponds to varies widely . In the Human genome, the centimorgan is about 1 million base pairs . </P>
