Question 1 of 10 1.0 Points Place the order of events in chromosome packaging from beginning to end. A. sister chromatids, DNA double helix, chromatin, nucleosome B. Chromatin, nucleosomes, DNA double helix, sister chromatids C. DNA double helix, nucleosome, sister chromatids, chromatin D. DNA double helix, chromatin, nucleosomes, sister chromatids Question 2 of 10 1.0 Points In nature, there is an exception to every rule. Of the species below, which one has a very unusual genome that violates the “rule”? A. Borrelia burgdorferi, the bacterium responsible for Lyme disease, has a linear genome and up to 21 plasmids. B. E. coli, a common bacterium in the human intestine, has DNA nucleotides A, T, C, and G, with only one OH group on the sugar moiety. C. Humans have a genome formed from 23 pairs of linear chromosomes, each of which is so long that it must be wrapped up and condensed into a special structure to fit in the nucleus. D. Arabidopsis pollen is haploid, carrying only one copy each of five linear chromosomes.
