These are arranged into 23 pairs. Functions of a Chromosome: The chromosome does not hold only the genetic code of an individual, but also many of the proteins help in its expression. At this point, each chromosome actually consists of a set of duplicate chromatids that are held together by the centromere.The centromere is the point of attachment of the kinetochore, a protein structure that is connected to the spindle fibres (part of a structure that pulls the chromatids to opposite ends of the cell). A chromosome is a string of DNA wrapped around associated proteins that give the connected nucleic acid bases a structure. Most eukaryotic chromosomes include packaging proteins called histones which, aided by chaperone proteins, bind to and condense the DNA molecule to maintain its integrity.
