Cell Division and Mitosis Notes

These flashcards are designed to help you with reviewing the lecture notes.

Interphase

The longest portion of a cell's life cycle.

M Phase

A very short period of the cell's life cycle focused on dividing genetic material

M phase

Taking all of the genetic material that's in the nucleus and dividing it.

Cytokinesis

Split the cell completely.

Interphase

When cells divide and grow faster.

Mitosis

The first of the options of M phase, which is crucial for understanding future concepts.

Mitosis

The second round of division of meiosis.

Chromatin

Looks like a big ball of yarn, essentially with no real organization or distinction.

nucleosomes

DNA condenses around histones to make __.

Mitosis

The goal is to produce two genetically identical daughter cells.

Mitosis Function

Growth, maintenance, and repair in multicellular organisms

Mitosis Function

Asexual reproduction in unicellular organisms

Unicellular

Organisms only undergo mitosis and go through asexual reproduction.

Multicellular

Humans, plants, other types of animals, fish, etc.

Meiosis

Complicated things that we're gonna talk about that are very different. It is all about productive division.

PMAT

It's prophase, metaphase, anaphase, and telophase, and it has to happen in that sequence.

Genetic Material

The organizational state of the genetic material.Is it chromatin? Is it a chromosome? And if it's a chromosome, is it duplicated?

Prophase

The first stage of mitosis

Duplicated chromosomes

two sister chromatids joined by a centromere

Prophase

We break down the nuclear membrane.

Prophase

Those centrioles separate and they move to the opposite poles. They go to the North Pole and they go to the South Pole.

Prophase

The spindle apparatus. Microtubules that we had a look at in our cell biology diagram that's a kind of scaffolding system that exists.

Metaphase

The phase that is always an equatorial phase.

metaphase

Duplicated chromosomes

Anaphase

Separatory phase. To separate the sister chromatids.

Chromatin

Term for an unduplicated chromosome, a chromatid, or daughter chromosome.

Telophase

Literally the opposite of phases that happened in prophase.

Anaphase

Split them at the centromeres like draw and quartering an individual.

Cytokenisis

Cleavage furrow that helps make separate identical cells.
