Numbers and Genetics (will update time to time)
Human genome; 1. ~3,000*10^6 bases (just remember that it is around 1 CD capacity - 3-4GB) 2. ~20,000 Protein coding genes 3. ~1% of genome --Protein coding exons human SNP; bases change in every 1000 bases therefore, human SNPs (3000*10^6)/1000 = 3 millions (3*10^6) Genome different within the species (except twins) 99.9% identical PS.There is a group of people interested in the same thing; http://book.bionumbers.org/ https://bionumbers.hms.harvard.edu/search.aspx -- Prefix for number Ref: https://en.wikipedia.org/wiki/Metric_prefix
