Eucaryotic cell division is a more complex <strong>and</strong> time<br />
consuming process than binary fission<br />
Features of Eucaryotic DNA<br />
1. DNA is in multiple linear chromosomes.<br />
Unique number for each species:<br />
• Humans have 46 chromosomes.<br />
• Cabbage has 20, mosquito 6, <strong>and</strong> fern over 1000.<br />
2. Large Genome: Up to 3 billion base pairs (humans)<br />
Contains up to 50,000-150,000 genes<br />
Human genome project is determining the sequence of entire<br />
human DNA.<br />
3. DNA is enclosed by nuclear membrane.<br />
Correct distribution of multiple chromosomes in each<br />
daughter cell requires a much more elaborate process<br />
than binary fission.
