The Cell Cycle

The Cell Cycle. Sections 5.1-5.2. The cell cycle is a regular pattern of growth, DNA replication, and cell division. Four Main Stages. The cell cycle has four main stages: Gap 1 (G1) Synthesis (S) Gap 2 (G2) Mitosis (M) Prophase Metaphase Anaphase Telophase Cytokinesis. Interphase.

The Cell in Action

The Cell in Action. Chapter 4. Exchange with the environment. Section 1. Introduction. An organism must be able to obtain energy and raw materials and get rid of wastes These functions keep cells healthy so that they can divide Cell division allows organisms to grow and repair injuries

Chromosome structure

Chromosome structure. Chromosomes. Example - an organism is 2n = 4. Chromosomes 1 & 2 are homologous chromosomes Chromosomes 3 & 4 are homologous chromosomes Chromosomes 1 & 3 came from the mother Chromosomes 2 & 4 came from the father. Life cycle. Cell division - Mitosis.

Biology

Biology. The Cell Cycle & Mitosis Video. Cell Cycle. Cell division occurred in: Reproduction (asexual vs. sexual) Overall growth Repair (skin cells for example) Dividing cells follow something called the cell cycle . Only 10% of the cell cycle is devoted to cell division (mitosis).

Chromosomes

Chromosomes. Human Chromosomes. Human cells have 23 pairs of chromosomes ( homologous pairs ) for a total of 46. One member of each pair comes from the sperm and the other from the egg. Each chromosome in the homologous pair will contain the same genes (possibly different alleles). Mitosis.

How do cells grow and Divide?

How do cells grow and Divide?. Chapter 2 section 3. Why do they need to divide. 1. To make more 2. They also need to be efficient in getting materials around the cell 3. If they are too large then the cell will not function efficiently. Cell division.

Meiosis and mitosis

Meiosis and mitosis. By trimbiel. step. 1. Prophase: chromosomes condense, nuclear membrane dissolves 2. Metaphase: chromosomes line up in the middle of the cell 3. Anaphase: chromosomes separate by being pulled to opposite sides of the cell by spindle fibers.
