Which of the following best describes how chromatin modifications are passed to the second copy of the genome following DNA replicationAn explanation on the explanation doc is not required for this question. 2 Chromatin blob identification and characterization of imaged and modeled chromatin.
DNA molecules first wrap around the histone proteins forming beads on string structure called nucleosomes. The primary function of chromatin is to compress the DNA into a compact unit that will be less voluminous and can fit within the nucleus. Which of the following best describes the authors purpose in the passage.
Chromatin is the association between DNA and proteins called histones. The nucleus was carefully isolated and the chromatin obtained. Chromatin is a mass of genetic material composed of DNA and proteins that condense to form chromosomes during eukaryotic cell division.
Two copies of each of the following proteins. Heterochromatin is highly condensed because in that state the union between DNA and proteins is very strong and they are very close. Chromatin is a genetic material or a macromolecule comprising of DNA RNA and associated proteins which constitute chromosomes in the nucleus of an eukaryotic cell.
