WebMar 31, 2024 · Prokaryotic chromosomes consist of double–stranded circular DNA. The genome of a cell is often significantly larger than the cell itself. For example, if the DNA from a human cell containing 46 chromosomes were stretched out in a line, it would extend more than 6 feet (2 meters)! WebEukaryotic cells, like yours, are 30 to 100 µm. b. no nucleus. This means that their chromosome, where the genes are, is not enclosed in a membrane. c. single, circular chromosome (you have 46 linear chromosomes in the nuclei of your cells). This single chromosome has relatively few
WebOct 2, 2024 · Chromosomes vary extensively between different organisms.

WebAs prokaryotic cells do not contain nucleosomes, they do not have the benefit of being able to use them to store negative supercoiling. However, they do contain enzymes, _____, that introduce supercoiling into the chromosomes. As the chromosomes are circular, they are more _____ constrained and unable to release that stored supercoiling. ===== … the skills of a social workerWebApr 9, 2024 · In bacterial cells, the genome consists of a single, circular DNA chromosome; therefore, the process of cell division is simplified. Karyokinesis is unnecessary because there is no nucleus and thus no need to direct one copy of the multiple chromosomes into each daughter cell. This type of cell division is called binary (prokaryotic) fission. myob issues todayWebMay 11, 2024 · Eukaryotic cells have a double membrane (the nuclear membrane ) surrounding the nucleus, the organelle that contains several chromosomes.
