Unit 6: Mitosis and the Cell Cycle

Reproducing cells, DNA refresh and more

What does DNA stand for?

Deoxyribonucleic acid

Where is DNA located in Eukaryotes?

The Nucelus

Function of DNA

carry genetic code

What is the monomer of a DNA

Nucleotides

What 3 things are DNA made of?

1.) Deoxyribose Sugar

2.) Phosphate Group

3.) Nitrogenous Base

What part of DNA determines the person’s traits

Nitrogenous Base

What are the 4 bases in the nitrogenous base

1. Adenine

2. Thymine

3. Guanine

4. Cytosine

What does the Chargaff rule say?

All Adenine matches with Thymine and all Guanine matches with cytosine.

All matching Adenine and Thymine matches are equal in the sample for DNA. The same goes for Guanine and Cytosine.

(A)

Adenine

(T)

Thymine

(G)

Guanine

(C)

Cytosine

Rosalind Franklin

The British Scientist that found the general shape of DNA using X-RAY diffraction

G1

Cell Growth, carrying routine functions, making new proteins and organelles.

S phase

DNA Replication. S=synthesis

G2

Cell makes final preparations for cell division by forming centrioles and other special structures.

Subdivisions of Mitosis

1. Prophase

2. Metaphase

3. Anaphase

4. Telophase

Mitosis

Process of division

Cytokinesis

Division of cytoplasm that occurs after mitosis.

Cytokinesis of Plant Cells

Form a cell “plate” between the 2 nuclei
