The length of DNA is usually DEFINED as number of nucleotides (or a pair of nucleotide referred to as base pairs) PRESENT in it This also is the characteristic of an organism. For example, a bacteriophage KNOWN as `phixx 174` has 5386 nucleotides, Bacteriophage lambda has 48502 base pairs [bpl, Escherichia coli has `4.6 xx 10^(6)` bp and haploid content of human DNA is `3.3 xx 10^(9)` bp. |
