(c) Identify the plasmid that must contain the CD3y core promoter sequence but the fewest or no negative regulatory sequences. Based on the data in Figure 2, describe the most likely
cause of the variation in luciferase activity among the cells that contain plasmids pCD37-419. pCD37-309, pCD37-239, and pCD37-199. Calculate the approximate percent increase
in luciferase activity between cells containing plasmid pCD37-59 and cells containing plasmid pCD37-149. Round to the nearest whole number.

each of the 46 original chromosomes splits into two daughter chromosomes, so there are two sets of 46 daughter chromosomes that end up in each cell. human cells have 46 chromosomes. each chromosome consists of a pair of identical chromatids attached together by a structure called a centromere.
