Presentation transcript:

Cell Reproduction Unit

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

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

Chromosome Formation

Chromosome Structure (cont) Chromatid Centromere

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

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

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

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