1. Cell Reproduction Unit

2. Chromosome Structure
- chromosome = a long continuous thread of DNA that consists of numerous genes with regulatory information coiled around proteins in compact structures

3. Chromosome Structure
- DNA wraps around proteins (called histones) to become compact

4. Chromosome Formation

5. Chromosome Structure (cont)
Chromatid
Centromere

6. Asexual Reproduction
= reproduction of offspring from one parent
- offspring are genetically identical to the parent
…this is a BAD thing

7. Asexual Reproduction Advantages: can reproduce alone-no mate
time (as quickly as 20 minutes)

8. Asexual Reproduction Disadvantages: offspring lack diversity
changes in environment affect 1 and all

10. Sexual Reproduction
= reproduction of offspring from two parents
- offspring are genetically different from the parents
…this is a GOOD thing
