what is an ester? and how do we identify an ester? Ester is the condensation product of an Carboxylic acid and alcohol in organic chemistry.In condensation two molecules combine such that the eleimination of small molecule like water takes place. Or it could be said that ester are dehydration product of alcohol and carboxylic acid. Reaction could be written as : RCOOH (Carboxylic acid) + HO-R' (alcohol) → RCOOR' (Ester ) Esters can be identified by the presence of -COO- linkage in the organic compound.

HISTONE STRUCTURE AND THE ORGANIZATION OF THE NUCLEOSOME Since DNA is supercoiled around the octamer in the nucleosome, and nucleosomes themselves can be organized into the 30-nm filament, the association of histones with DNA results in considerable compaction and allows DNA that is over a meter long to be organized in a cell nucleus that is only microns in diameter.
