100
In this phase, chromosomes line up at the metaphase plate.
What is metaphase?
100
This is the nondividing state that a cell enters if it doesn't pass the G1 checkpoint.
What is G0?
100
This is the location of DNA in the cell.
What is the nucleus?
100
This blue-tinted movie features the two awkward main characters in a biology class.
What is Twilight?
200
In this phase, chromatin condenses and the mitotic spindle begins to form.
What is prophase?
200
This is the name of the signals involved in passing or failing checkpoints.
(Hint: think of a traffic light)
What are stop/go signals?
200
A string of nucleosomes.
What is chromatin?
200
Bella and Edward slide this device back and forth to take a closer look at the cells.
What is a microscope?
300
In anaphase, microtubules shorten and separate these.
What are sister chromatids?
300
DNA replication and DNA damage is checked for in this checkpoint.
What is the G2 checkpoint?
300
This is the point at which the sister chromatids are connected.
What is the centromere?
300
This is what Bella and Edward win in their biology class.
What is a golden onion?
400
In this phase, two daughter nuclei form.
What is telophase?
400
This is the name of programmed cell death.
What is apoptosis?
400
These are another name for body cells.
What are somatic cells?
400
Bella and Edward use this part of a plant to study chromosomes.
What is an onion root?
500
This is the phase in which the nuclear envelope fragments.
What is prometaphase?
500
The cell will pause mitosis to allow for spindles to finish attaching to chromosomes if it gets stopped at this checkpoint.
What is the M (Spindle) checkpoint?
500
These is the protein responsible for holding the sister chromatids together.
What is cohesin?
500
This is the name of the main character who shares a name with title of the show that first aired in 1996.
Who is Sabrina (the teenage witch)?
