WebAssignment: Cell Structure and Function Describe the differences between prokaryotic and eukaryotic cells. Answer: Prokaryotic cells are typically smaller and simpler in structure than eukaryotic cells. They lack a nucleus and membrane-bound organelles and have a single circular chromosome. In contrast, eukaryotic cells are larger and more complex, … WebIn this article, we'll take a closer look at why telomeres are needed, why they shorten during DNA replication, and how the enzyme telomerase can be used to extend them. The end-replication problem Unlike bacterial chromosomes, the chromosomes of eukaryotes are linear (rod-shaped), meaning that they have ends.

WebApr 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. WebMar 6, 2024 · Eukaryotic cells are larger in size than prokaryotic cells and have a more complex structure. Eukaryotes are divided into four main groups: animals, plants, fungi, and protists. Structural features: Eukaryotic cells have a distinct nucleus, which houses the genetic material in the form of multiple linear chromosomes.
