M phase

Why is dna important

It contains instructions to make proteins which affect many different processes in the cells

What is a gene

A small section of DNA containing the instructions to make a type of protein

What are chromosomes?

They are made up of DNA and loosely spread out the nucleus and strings of chromatin during M phase

What do chromosomes look like

X

What is the centromere

Where the sister chromatids meet

Each side of the chromosome are

Sister chromatids

How many chromosomes do humans have

46, two of each 23 types

Homologous chromosome

Set of chromosomes that have the same gene in the same place

Mitotic spindle

Microtubules or spindle fibers that are made my centrioles and will separate the chromosomes during mitosis

Phrophase

Chromatin condenses into chromosomes and spindle fibers are created from the centrioles

Metaphases

Spindle fibers attach to the centromeres and chromosomes line up in the middle

Anaphase

Spindle pulls sister chromatids apart and they start to separate

Telophase

Chromosome reach opposite ends and the nuclear membrane starts to form, spindle dissolves, chromosomes condense

Cytokinesis

The cell finally splits apart into two identical daughter cells
