Study Notes
DNA Concentration in Prokaryotic Cells
- The term "nucleoid" refers to the region in a prokaryotic cell where the DNA is concentrated.
- Prokaryotic cells do not have a defined nucleus, and their DNA is typically a single circular chromosome.
DNA Organelles in Eukaryotic Cells
- The organelle that contains most of the DNA in eukaryotic cells is the nucleus.
- Eukaryotic cells can have multiple linear chromosomes and possess a more complex structure than prokaryotes.
Meaning of 'Eukaryotic'
- "Eukaryotic" derives from Greek roots meaning "true nucleus."
- Eukaryotic cells are characterized by having a well-defined nucleus and membrane-bound organelles.
Meaning of 'Prokaryotic'
- "Prokaryotic" means "before nucleus," indicating that these cells lack a true nucleus.
- Prokaryotic cells are typically smaller and simpler than eukaryotic cells.
Location of DNA in Prokaryotic Cells
- DNA in prokaryotic cells is located in the nucleoid region, which is not enclosed by a membrane.
- Additionally, prokaryotes may contain plasmids, which are small circular DNA molecules separate from the chromosomal DNA.
