In this checkpoint, the cell asks: is the environment favorable?
What is the G1 checkpoint
100
Name the six phases in the cell cycle (in order)
What is PROPHASE, PROMETA, METAPHASE, ANAPHASE, AND TELOPHASE, CYTOKINESIS

At this checkpoint, the cell asks: Has all of the DNA been replicated? Is all damage repaired?
What is the G2 checkpoint
200
This structural protein of tissue is the the main source of tensile strength.
What is collagen
200
This formation of procaspases lead to apoptosis
What is the apoptosome
300
Regulatory proteins such as Cdc6 bind to this complex ________.
Origin Recognition Complex, which remains bound to the origin of replication.
300
In this phase, the chromosomes condense
What is PROPHASE
300
Explain the difference between a hemidesmosome and a desmosome
Hemidesmosome: filament + Basal Lamina Desmosome: filament + neighboring cell filament
300
This is the center region of the chromosome (which attaches to the kinetochore), while this is where the microtubules "aster" forms
What is Centomere "mirror" and Centrosome=aster
400
If condensins in your cell were overreactive, would your chromatin be translated?
It would not be translated.
400
In this phase, the nuclear envelope starts to form around the individual chromosomes
What is TELOPHASE
400
While desmosomes utilize ___ proteins to connect, hemidesmosomes use _____ proteins for connection.
desmosomes= cadherins hemidesmosomes= integrins
400
During _________nuclear pore proteins and lamins are phosphorylated causing them to separate the membrane, which is broken down into vesicles
What is prometaphase
500
AKT prevents apoptosis by phosphorylating what?
BAD

While apoptosis is a highly regulated, clean process, this other event results in a destructive cell suicide
What is Necrosis
500
The orientation of _____ in Cellulose gives plants direction? Cellulose will interact with these three other molecules to make up cellular ECM.
What is the orientation of micofibrils in Cellulose? Cellulose microfibrils interact with polysaccharides (1), Pectin (2), and Lamella (3).
