From the bionet.info-theory newsgroup, eddy@boulder.Colorado.EDU (Sean Eddy) writes in article <eddy.725706161@beagle>: >Alberts (_Molecular Biology of the Cell_, p. 412) cites 2 x 10^8 >nt/min as the average interphase total transcription rate per >mammalian cell. 40% of that is tRNA/rRNA transcription; so call it >1x10^8 nt/min for precursor mRNA transcription. >Now you need a number for how much precursor is spliced out before >export from the nucleus; I think a reasonable guess in the human >might be 95%. >Call each nucleotide 2 bits of information, and you get a "data >transmission rate" on the order of 200 kilo(bytes)/sec -- so it's >closer to Ethernet than an obsolete modem :) I did say 300-1200 baud was a GUESS. -- Ken Easlon | "...somebody spoke and I went into a dream..." ken@holonet.net | -Paul McCartney Pleasantly Unaffiliated |
