How many base pairs are in a typical gene

With the exception of identical twins, all humans show significant variation in genomic DNA sequences. The human reference genome (HRG) is used as a standard sequence reference. There are several important points concerning the human reference genome: • The HRG is a haploid sequence. Each chromosome is represented once. WebExact M.W. of ssRNA (e.g., RNA Transcript): M.W. = (An x 329.2) + (Un x 306.2) + (Cn x 305.2) + (Gn x 345.2) + 159ª An, Un, Cn, and Gn are the number of each respective nucleotide within the polynucleotide. M.W. calculated is valid at physiological pH. ªAddition of "159" to the M.W. takes into account the M.W. of a 5' triphosphate.
