Question - What is the difference between DNA, chromatin, and chromosomes? What is the significance of each form?.
Answer - Chromosomes are the gene carrying structure. (Campbell, Simon, Reece, & Dickey, 2010, p. 122) Chromosomes have a long DNA molecule packaged with proteins in it. DNA is considered as the genetic code inherited form parents. (Campbell, Simon, Reece, & Dickey, 2010, pp. G-5) Chromatin is a combination of DNA and protein molecules. Each form is important in cell division. Chromosomes are composed of chromatin. During cell division, the chromosomes align during metaphase. In anaphase the chromatids separate and results in chromosome doubling. DNA's significance is to carry genes to the daughter cells. All three of these are pretty much the same things just in different states. Chromosomes package the DNA, they then become uncoiled to prepare for Cell division. Chromatin separate and produce the daughter cells from the uncoiled chromosomes. It is quite interesting the roles the three play in each phase of cell division.
