WebFeb 5, 2016 · The size of a double stranded DNA molecule is measured by the number of base pairs it contains and a single strand is measured by the number of nucleotides it has. As humans, we have a total of 6,000,000,000 base pairs in all of our chromosomes and the entire sequence of base pairs was published by the Human Genome Project in 2003. WebWhen an absorption spectrum is measured, nucleic acids absorb light with a characteristic peak at 260 nm. The fluorometric measurement of nucleic acids is based upon the use of fluorogenic dyes that bind selectively to DNA or RNA. Typical RNA/DNA absorbance spectrum. Fluorescent dyes selectively bind to DNA, RNA or protein.
