1. Mitosis and Meiosis Review

2. What does DNA stand for?
Deoxyribonucleic Acid
What is the monomer of DNA?
Nucleotide
What are the 3 things that make up the nucleotide?
Sugar (Deoxyribose in DNA)
Phosphate
Base
What are the 4 bases called?
Adenine
Thymine
Guanine
Cytosine
Who “discovered” DNA?
Rosalind Franklin

3. Why must DNA replication occur?
So that each cell has a copy of DNA
List the 3 steps of DNA replication.
Helicase splits the DNA molecule into 2 strands
DNA Polymerase brings in free nucleotides and “matches up complimentary bases”
3. Ligase “glues” the nucleotides together
Why does Mitosis and Cell Division occur?
So that old cells can be replaced by new cells
List the stages/phases of Cell Division.
Interphase, Prophase, Metaphase, Anaphase, Telophase, Cytokinesis
List the stages/phases of Mitosis.
Prophase, Metaphase, Anaphase, Telophase

4. What is the net result of Mitosis?
2 cells exactly identical to the original cell
What is created in Meiosis?
Gametes – Egg and sperm cells
What is the net result of Meiosis?
4 cells with half the number of chromosomes that are not genetically identical to one another
Remember I did not even put in things like the specifics of each phase/stage, diagrams, spindle fibers, centrioles, chromosomes, sister chromatids, haploid, diploid, tetrad, homologous chromosomes etc……
