  1. Histones are an essential class of proteins for packaging DNA into chromosomes. Would you expect there to be more histones (proteins, not histone genes) per kilobase of DNA in euchromatin or in heterochromatin of a living cell? Why?

Answer #1

Hetrochromatin would have more histone protein per kB of DNA because they are inactive segment of chromosome and are tightly packed (for which histone are required)

  • Euchromatin are transcipitanolly active and loosely packed therefore they will have less histone
