Stages of Cell Cycle
Chromosome structure
Mitosis
Cell Signaling
Signal Transduction pathways
100
Cell cytoplasm divides
What is cytokinesis?
100
Long, thin fibers of DNA and proteins
What is chromatin?
100
Chromosomes are unwinding and become enclosed in the nucleus, and the cell begins to divide
What is telophase?
100
What are receptors?
The proteins in the cytoplasm responsible for a cells reponse to a signaling molecule.
100
Individual molecules that are second messengers
What is cAMP, Phosphotidyl Inositol & Calcium
200
DNA replicates
What is the S phase?
200
One half of a duplicated chromosome
What is a sister chromatid?
200
Chromosomes are lined up on the cell's equator
What is metaphase?
200
What is kinase?
This is an enzyme catalyzing transfer of a phosphate group.
200
What is second messenger?
The signaling process by which a G protein relays information to an intracellular signaling agent.
300
The cell grows and carries out normal activities after division has occurred
What is the G1 phase?
300
Holds two sister chromatids together
What is a centromere?
300
The cell's chromosomes become visible, the nuclear membrane disappears, and the centrioles move to opposite sides of the cell
What is prophase?
300
Times cell divides in each cell cycle
What is once?
300
Prokaryotes divide this way
What is binary fission?
400
The stage that includes G1, S, and G2
What is interphase?
400
Visible structure seen beginning in prophase
What is a chromosome?
400
Chromatids are pulled apart and become individual chromosomes
What is anaphase?
400
What is a Protein Phosphatase.
These are any enzymes that can remove a phospate group for a protein.
400
Cyclic Adenosine Monophosphate (cAMP)
This chemical is formed from ATP when Addenylyl Cyclase gets activated by a G-Protein.
500
What are the phases of cell cycle
G1, S, G2 and M( Mitosis and Cytokinesis)
500
Fibers attached to kinetochore bound to centromeres of each chromosome
What are Kinetochore fibers?
500
Spindle fibers appear and attach to centromeres
What is prophase?
500
Cyclic Adenosine Monophosphate

A change in shape of the receptor causes changes in the G protein. In the G protein, the α subunit binds GDP but when activated, GDP is exchanged for GTP; α subunit simultaneously dissociates from β and γ Activated G protein transmits signals by binding other proteins
Describe the mechanism of activation of G proteins.
