Bozeman Mitosis Video Guide

Basic Biology Cell Cycle

Vital life processes that require mitosis

Regeneration, development, asexual reproduction, and wound healing

Difference between a haploid cell and a diploid cell?

Haploid has one copy and diploid has two copies

What are the haploid and diploid numbers in humans?

N=23, 2N=46

What are the three parts of interphase?

G1, S, G2

G1

Cell grows larger

S

Cell stops growing and DNA replication occurs

G2

Cell continues to grow

What is G0?

Cells that don't make copies of themselves

A cell spends most of its time in which phase?

Interphase

One side of a chromosome is a...

Chromatid

The middle of a chromosome is the...

Centromere

Chromosomes have short and long...

Arms

Chromosomes have two chromatids after they have passed through the ______ phase

S

Prophase

The nucleoli a disappears, chromatin condenses into chromosomes, separation of centromeres occurs, and the formation of the mitotic spindle

Pro Metaphase

The nuclear envelope disassembles, chromosome forms two Kinetochores at the centromere l, and microtubles attach to the centromere

Metaphase

Chromosomes align in metaphase plate; meet in the middle

Anaphase

Chromatids separate towards opposite poles; move apart

Telophase

New nuclear envelope forms, chromosomes unfold back into chromatin, nucleoli reappears, cell continues to enlogate

Cytokinesis

Daughter cells divide

Mitosis in plants vs. animals

Instead of "zipping" in half, plants have to build a cell plate in between the cell because of a cell wall

What disease results from cells reproducing out of control?

Cancer(tumors form)

How are the frequencies of smoking and lung cancer related?

Chemicals found within can cause mutations and cause cells to jump in and become cancerous; cells reproducing out of control
