Cell Vocab
A Stem Cell can do what?
The cell grows and makes proteins here, first part of cell cycle
G1
A nuclear membrane forms around each new set of chromosomes
Telophase
Small fiber made from microtubules that help position chromosomes during mitosis
Spindle Fibers
Cytoplasm division is referred to as what?
Cytokinesis
Differentiated cells are cells that have a specific function, name two types
Muscle, Nerve, Skin, Epithelial, Blood, etc...
The third step in the cell cycle where the cell also grows and makes proteins, but also prepares for cell division
G2
Centrosomes start pulling on spindle fibers to pull sister chromatids apart
Anaphase
Structure that holds sister chromatids in chromosomes
centromere
True or False: Cytokinesis is the last phase of mitosis
False
Two reasons cell divide are...
Growth and Repair
DNA replication occurs here
S Phase
Sister chromatids migrate to the center of the cell along a "plate"
Metaphase
Chromatin is DNA found in a ________ form
loose
The end result of mitosis is _______ ________ ___
2 Daughter cells
2 words: This refers to the overall life of cells from growth to cell division
Cell Cycle
Cells spend 90% of their life here
Interphase
The membrane around the nucleus disintegrates, and the chromosomes condense to become sister chromatids. Also the centromeres migrate to opposite poles of the cell and spindle fibers start to emerge
Prophase
This is the structure that spindle fibers are projected from
Centrosome
Write the stages of mitosis in order
Prophase, Metaphase, Anaphase, Telophase
Asexual reproduction in bacteria is referred to as this
Binary Fission
If a panda has 26 chromosomes, how many chromosomes will it have after DNA replication?
52
How many chromosomes does each new daughter cell have if the cell starts with 48 chromosomes
48, same as the original cell!
In which phase do chromosomes become visible
Prophase
The name of a duplicated chromosome
Sister Chromatid
