During what phase the nucleus begin to break down?
Prophase
100
What cells undergo meiosis?
Cells of the ovaries and testes
100
How many strands does an RNA molecule have?
2 strands
100
What determines if you may be at greater risk for a genetic disorder?
Your DNA
100
What cellular process gone wrong leads to cancer?
Mitosis
200
During what phase the nucleus begin to re-appear?
Telophase
200
What is the name for the cells that meiosis produces?
gametes
200
What RNA molecule "reads" the DNA and transfer the information to the ribosomes?
mRNA or messenger RNA
200
What sequence of 3 repeating DNA letters will give you Huntingtons Disease?
CAG
200
What enzyme allows cancer cells to live forever?
Telomerase because it extends the telomeres and therefore the cell can replicate and infinite amount
300
How many cells does mitosis produce?
2 identical cells
300
If I begin meiosis with a 4n diploid cell what cell will I get in the end?
2n haploid cell (half the information)
300
What RNA molecule "reads" the mRNA molecule and brings the amino acids to make a growing chain called a protein
tRNA or transfer RNA
300
What is a chromosomal duplication?
When chromosomal information is duplicated onto a chromosome twice
300
If you sent in your DNA and you have a gene for cancer will you get it? Why or why not?
No just because you have the gene it does not mean you will get cancer. You are more likely to but environmental factors also play a role.
400
If during mitosis I have a 4n cell what cell will I end up with?
Another 4n cell (identical to the original)
400
During which phase of meiosis does crossing over occur?
Metaphase I
400
What are the 3 parts of a nucleotide
Sugar, phosphate, nitrogenous base
400
What type of substitution caused the red blood cells to be sickle shaped?
single base substitution
400
What does apoptosis mean?
cell death, the cell kills itself for having defects
500
What are all the phases of mitosis in order?
Prophase, Metaphase, Anaphase, Telophase
500
How many new cells does meiosis produce?
4 new cells
500
Name one sequence of 3 letters called a codon that tells the ribosome to "start" building a protein
AUG
500
What type of DNA mutation causes cystic fibrosis?
It was a 3 DNA base deletion not allowing the mRNA to eventually make the amino acid phenolalanine
500

survivin
