how to convert base pairs to kilobase pairs
Base pair The size of an individual gene or an organism's entire genome is often measured in base pairs because DNA is usually double-stranded. Hence, the number of total base pairs is equal to the number of nucleotides in one of the strands (with the exception of non-coding single-stranded regions of telomeres). The haploid human genome (23 chromosomes) is estimated to be about 3.2 billion bases long and to contain 20,000–25,000 distinct protein-coding genes.[2][3][4] A kilobase (kb) is a unit of measurement in molecular biology equal to 1000 base pairs of DNA or RNA.[5] The total amount of related DNA base pairs on Earth is estimated at 5.0 × 1037, and weighs 50 billion tonnes.[6] In comparison, the total mass of the biosphere has been estimated to be as much as 4 TtC (trillion tons of carbon).[7]
Karyotype The basic number of chromosomes in the somatic cells of an individual or a species is called the somatic number and is designated 2n. In the germ-line (the sex cells) the chromosome number is n (humans: n = 23).[2]p28 Thus, in humans 2n = 46.
