WebThe chromosome scaffold, which is made of proteins such as condensin, TOP2A and KIF4, [33] plays an important role in holding the chromatin into compact chromosomes. Loops of 30 nm structure further condense with scaffold into higher order structures. [34] WebTools. A bacterial artificial chromosome ( BAC) is a DNA construct, based on a functional fertility plasmid (or F-plasmid ), used for transforming and cloning in bacteria, usually E. coli. [1] [2] [3] F-plasmids play a crucial role because they contain partition genes that promote the even distribution of plasmids after bacterial cell division.
WebTo put that another way, meiosis in humans is a division process that takes us from a diploid cell—one with two sets of chromosomes—to haploid cells—ones with a single set of chromosomes. In humans, the haploid cells made in meiosis are sperm and eggs. When a sperm and an egg join in fertilization, the two haploid sets of chromosomes form a …
