CORRECT/ACCURATE ANSWERS


Heredity - CORRECT ANSWERS- The process of how genes
transmit traits from parents to offspring



What are the three parts of Interphase in the cell cycle? -
CORRECT ANSWERS- 1. G1

2. S

3. G2



What are the primary cellular activities during *G1* phase? -
CORRECT ANSWERS- Chromosomes are not duplicating or
dividing. This is a growth period before duplication



What are the primary cellular activities during *S* phase? -
CORRECT ANSWERS- Duplication of chromosomes into sister
chromatids.



They remain joined at the centromere and are considered as 1
chromosome as long as they are joined at the centromere

, What are the primary cellular activities during *G2* phase? -
CORRECT ANSWERS- Synthesis of proteins required for mitosis



What are the 5 stages of mitosis? - CORRECT ANSWERS- 1.
Prophase

2. Prometaphase

3. Metaphase

4. Anaphase

5. Telophase/cytokinesis



What are the primary cellular activities during *Prophase*? -
CORRECT ANSWERS- Chromosomes condense and become
visible. Centrosomes move apart toward opposite poles. Nucleoli
begin to dissolve. Nuclear envelope is still inact



What are the primary cellular activities during *Prometaphase*? -
CORRECT ANSWERS- The nuclear envelope breaks down.
Microtubules invade the nucleus and connect to kinetochores in
centromere of each chromatid



Kinetochores - CORRECT ANSWERS- Specialized structure at
centromere of each chromatid that function in conveyance of
chromatids along microtubules



What are the primary cellular activities during *Metaphase*? -
CORRECT ANSWERS- Chromosomes align on the metaphase plate
with sister chromatids facing opposite poles
