#21-34 Module 3 - cell division

It's all me in my head I'm the one who burned us down But it's not what I meant Sorry that I hurt you I don't wanna do, I don't wanna do this to you I don't wanna lose, I don't wanna lose this with you I need to say, hey It's all me, just don't go Meet me in the afterglow

(21,25)Cell division

it is the process of **splitting a single cell into new cells**

(21,15)Chromosomes

Long DNA molecules with part or all of the genetic
material of an organism. Structures that contain genetic information.
**Made up of DNA and proteins** that carry genetic information.

(21,15)Centromere

Point where chromatid are joined

(21,15)Chromatid

**Chromosomes contain identical parts**. Strands composed of chromatin that makes up the chromosome.

(21,25)Chromatin

**Makes up the chromatid**. The indistinguishable mass of DNA
molecules whereas chromatids are part of a chromosome attached to it with a centromere.

(21,25)Cell cycle

It is the regular sequence of growth and division that **eukaryotic** cells undergo

(21,25)binary fission

Prokaryotic cells undergo.

(26,30)Interphase

this is where the **cell grows,** the cell makes a **copy of its DNA,** and the cell is **ready for division**

(26,30)G1

the cell starts to grow

(26,30)S

\
 the cell makes a copy of its DNA

(26,30)G2

\
the cell is ready to divide 

(26,30)46

how many chromosomes are in a human being

(31,34)Mitosis

production of identical cell for **growth** and **repair**

(31,34)Prophase

The stage of mitosis where the **chromosomes are more visible**

(31,34)Metaphase

The stage of mitosis where the **chromosomes line up in the middle**

(31,34)Anaphase

The stage of mitosis where the **centromere** that joins the sister chromatids **split**

(31,34)Telophase

The stage of mitosis where **Chromosomes uncoil**. Spindle fibers began to break and dissolve. **The start of cytokinesis**

Cellular proliferation

process by which a cell grows and divides to produce two daughter cells.

(26,30)Cytokinesis

is the **division of the cytoplasm** and the other parts of the cell. Results in two separate daughter cells with identical nuclei
