Unit 4: Cell Cycle Intro

​Cell Theory States

All Cells come from pre-existing cells

All Living things are made up of 1 or more cells

Cells are the basic unit of life

​It all starts with DNA!

It is the universal language and it is the blueprint of all living things.

It is a type of NUCLEIC ACID and it is housed in the Nucleus of Eukaryotic cells.

DNA can coil up and become something known as CHROMOSOMES, Chromatin!

​More specific

​

Chromosome Structure

Humans have 46 Chromosomes in total

Chromosomes are inside of all Cells, because DNA IS IN ALL LIVING THINGS.

DNA/Chromosomes must be able to equally divide inside of the Cell cycle to make cells in the body

VOCABULARY

Kinetochore: Where spindle Fibers
Attach to the chromosome
(for cell division/cell cycle)

VOCABULARY

Centrosome: (In the cytoplasm)
Is the unit of centrioles/spindle fibers that migrate to opposite "poles" of the cell to aid in cell division


Centriole: In the cytoplasm of cells and it produces spindle fibers to help with cell division (occurs in pairs)

​Cytokinesis (Splitting of the cell)

The process at the end of the Cell cycle that splits the original cell into TWO identical daughter cells.
