Quantitative biology database
BioNumbers - The Database of Useful Biological Numbers
Here’s a neat new website. It’s a repository of quantitative information on biological things (eg. organisms, biomolecules, etc.) Some stuff I found while glancing through:
Number of mRNA/cell in E. coli: 138
Volume occupied by all RNA in E. coli: 6%
Average gene length in mammals: 16.6kb
Average gene length in nematode C. elegans: 4 kb
Mutation rate per genome per replication in humans: 0.16 mutation/genome/replication
Average time between blinks in humans: 2.8 sec
Amount of photons necessary to excite a cone in humans: 100
Citations are included for most numbers too. The database seems a little sparse on neuroscience topics, so go over and contribute some numbers!
