What do we call a small peice of DNA that has the code for one specific characteristic in a living thing?
For an extra "double jeopardy": About how many of these do humans have in one of their cells?
What is gene and about 30,000.
200
In which phase of Mitosis do the chromosomes line up down the center of the cell and attach to the spindle fibers at their centromere?
What is Metaphase.
200
What is the name of the little ball ir "glue" that holds the chromosomes together and allows them to attach to the spindle fibers?
What is the centromere.
200
What is RNA used for?
What is to make proteins for the cell.

What are nitrogen bases.
300
In which phase of Mitosis do the spindle fibers form?
What is Prophase.
300
What is the name of the little "fising reels" that cast out the spindle fibers in Prophase and "reel" them back in during Anaphase?
What is centrioles.
300
What do we call it if there is a mistake in the code on the RNA copy?
What is the wrong protein is made and it is called a mutation.
300
Name two specific nitrogen bases that always make a pair (they cannot have been mentioned in this game yet).
What is it depends on the answer!!! I'll let you know if you are correct or not!
300
About how long does the cell cycle take from start to finish in an adult human?
What is 24 hours.
400
In which phase of Mitosis do two new nuclei form around the strands of DNA?
What is Telophase.
400
Other than growing to twice its size and doubling its organelles, what is the very important step in Interphase?
What is making a copy of the DNA strand.
400
Name one way the RNA is different from DNA.
What is it is a partial copy, or it is shorter, or it is a single strand.
400
Please name two nitrogen bases that always make a pair (you cannot rename two that were already mentioned in this game).
What is it depends! I will let you know if you are correct!
400
Please name the three reasons why cells divide. This is a "double Jeopardy" question.
What is 1. growth, 2. reproduction, 3. repair

In which phase of Mitosis do the centromeres split, the chromatids seperate and the spindle fibers "reel in" one of each chromatid to each side of the cell?
What is Anaphase.
500
What happens during Prophase other than the spindle fibers forming, the centrioles moving to opposite ends of the cell and the nuclear membrane starts to dissolve?
What is the DNA coils up to form chromosomes.
