How do prokaryotes divide? How many parent cells produce how many daughter cells

Divide by binary fission
1 parent cell and one daughter cell are produced.

How do eukaryotes divide? How many parent cells produce how many daughter cells

Divide by mitosis (type of nuclear division
there is one parent cell that produces 2 daughter cells

What is the process going on above?

Binary fission

What are chromosomes made of and what do they do

Chromosomes are made of DNA and protein and they carry genetic info in the form of genes

What are chromatin made of and what do they form

Chromatin are loose strands of DNA and Protein that wind up tightly to form chromosomes

What are centromeres made of and what do they do

It is a protein disk that holds chromatids together

What are kinetochores

where spindle is attached to chromosome

What are sister chromatids

two chromatids attached by centormere

What is the cell cycle and what are the phases

Series of events the cell goes through as it grows and divides

This includes Interphase, Mitosis, and Cytokinesis

What is Interphase and what are the different sub phases of it

It is the period between cell divisions.

G1, S, G2

What does G1 do in Interphase

Synthesis of new proteings and organelles, cell growth

What does S do n Interphase

DNA replication, synthesis of key proteins associated with chromosomes

What does G2 do in Interphase

Copies of organelles and molecules for cell divison

What is Mitosis and where does it occur

Mitosis is an example of nuclear division and it occurs in Somatic Cells (body cells)

Prophase

pulls centrioles to the poles

What stage is this?

Prophase

What phase is this

interphase

Metaphase

chromosomes line the equator

What phase is this

metaphase

What happens during anaphase

chromosomes get pulled towards poles

What phase is this

anaphase

telophase

chromosomes unwind, nuclear envelope forms

What phase is this

Telophase

What happens to the cytoplasm in cytokinesis

Cytoplasmic division
cytoplasm draws inwards into 2 equal parts

What phase is this

Cytokinesis

Do plants have centrioles or clevage furrows? Why?

Plants have rigid cell walls and cannot form cleavage furrows

When do sister chromatids separate

anaphase

When does cell growth occur

Interphase

When does nuclear division occur

Mitosis

When do chromosomes get distributed to daughter cell

mitosis

when is protein produciton high

interphase

when are chromosomes duplicated

interphase

When does DNA synthesis occur

interphase

after what period does cytoplasm divide

mitosis

When are mitochondira and other organelles made

interphase
