Mitosis Test

A cell's endowment of DNA (its genetic information)

All body cells have them EXCEPT for reproductive cells They contain 46 chromosomes

Reproductive cells (sperm and egg) They have 1/2 as many chromosomes as semantic cells so..... 23

A complex of DNA, associated with protein molecules -Eukaryotic cells are made up of this. -When cells are not dividing, the DNA is in the form of chromatin (46 speghetti like pieces) -Has DNA and histone proteins

-Each duplicated chromosome has 2 of these -Have identical DNA -Attached by adhesive protein along their length

Area where the two chromatids most closely attach

The division of the nucleus -DNA is splitting to ensure that each new daughter cell has a full set of DNA

Follows almost immediately after mitosis, -Division of the cytoplasm

-Produces egg and sperm cells -Yields non-identical daughter cells that have only one type of chromosome

Begins to form in the cytoplasm during prophase -Fibres are made of microtubules and associated with proteins

Assembly of spindle microtubules starts here. -Non membranous organelle that functions throughout the cell cycle to organize the cell's microtubules

-A non membranous organelle that functions throughout the cell cycle to organize cell's microtubules

A radical array of short microtubules, extends from each chromosome

Each of the two sister chromatids of a chromosome has one -Structure of proteins associated with specific sections of chromosomal DNA at the centromere

-"Division in half" -Prokaryotes produce it.
