CELL CYCLE The cell cycle is the activities that a cell goes through throughout its life

CHROMOSOMES The Chromosome Theory states that chromosomes are rod-shaped carriers of genetic information: DNA

What is a Chromosome? Chromosomes form when CHROMATIN (nuclear material containing DNA) condenses to form rod-shaped structures Chromosomes are found in the nucleus but are only visible when the cell is dividing

What are the Parts of a Chromosome? Each replicated copy of DNA is called a CHROMATID The two chromatids that make up a chromosome are held together by a point called a CENTROMERE

Relationship between Chromosomes, DNA, and Genes… Chromosomes are made of condenced DNA Each segment of that DNA that contains directions for a particular trait is a GENE

SEXUAL VS. ASEXUAL REPRODUCTION Requires union of TWO cells EGG + SPERM Offspring are a combination of traits from each parent GENETIC VARIETY! ASEXUAL REPRODUCTION One parent Offspring identical to parent Same exact genetic information Little variety
