Study Notes
Cell Division in Multicellular Organisms
- Cell division is necessary for growth, repair, and maintenance of tissues in multicellular organisms.
Cell Division in Unicellular Organisms
- The purpose of cell division in unicellular organisms is to reproduce and increase the population.
Genome
- A genome is the complete set of genetic information contained within an organism's DNA.
Genome Organization in Prokaryotes
- In prokaryotes, the genome is organized into a single circular chromosome.
