Requirements for precipitation first let s review the components we need to precipitate dna or rna with ethanol.

Biolabs dna ladder. The dna ladder consists of proprietary plasmids which are digested to completion with appropriate restriction enzymes to yield 10 bands suitable for use as molecular weight standards for agarose gel electrophoresis. A molecular weight size marker also referred to as a protein ladder dna ladder or rna ladder is a set of standards that are used to identify the approximate size of a molecule run on a gel during electrophoresis using the principle that molecular weight is inversely proportional to migration rate through a gel matrix. In dying cells dna is cleaved by an endonuclease that fragments the chromatin into nucleosomal units which are multiples of about 180 bp oligomers and appear as a dna ladder when run on an agarose gel.
