Where must a mutation occur in order to be inherited by offspring?

egg or sperm, or a parent cell of these

100
What does crossing over do? And when does it happen?
Crossing-over swaps parts parts between homologous chromosomes during prophase I so that genes can mixed (more variety) in the offspring
100
What is the difference between haploid and diploid?
Haploid has one set of chromosomes. Diploid has two sets of chromosomes. n vs 2n
100
What are the three parts of the cell cycle (in general whether is be mitosis or meiosis)? (Hint: the last part involves division of cytoplasm)
Interphase---> Mitosis or Meiosis -----> Cytokinesis.
100
What are the four types of macromolecules?
Lipids, Carbohydrates, Proteins, Nucleic Acids
200

Name one thing that can cause cancer.

UV light tobacco smoke chemical "mutagens"

200
How many daughter cells do you get at the end of meiosis? and are those cells different or identical to one another?
4 daughter cells that are all different.
200
Which process is asexual, and which process is sexual? Which one do you want if you want to produce gametes?
Asexual: mitosis, Sexual: meiosis, Meiosis/Sexual
200
What are the three stages within Interphase?
G1, S, G2
200
Name one hydrophobic substance, and one hydrophilic substance.
-phobic-"hating" -philic-"loving" examples-- hydrophobic: fats, oils, fatty acid tails in phospholipids hydrophilic: sugars, ions, phosphate heads in phospholipids
300
Name a possible result of mutation of a somatic cell.
cancer, cell death, no difference (silent mutation)
300

Why does meiosis reduce the number of chromosomes?

So egg and sperm can join to form offspring with the original chromosome number

300
which type of cell division produces somatic daughter cells?
Mitosis
300
What happens during the S phase of Interphase?
DNA replicates
300
Enzymes work by lowering the ____________.
Activation Energy
400

If something goes wrong during interphase, the cell is moved into what? G1, G3, or G0

G0

400
After meiosis I, before you begin meiosis II, you go through interphase again. True or False?
False
400
A diploid human cell that goes through meiosis. How many chromosomes will the daughter cells have at the end, and what types of cells might the daughter cells be?
23, egg or sperm
400
What is cytokinesis?
When the cytoplasm of both newly made cells physically separate from one another.
400
What ever the cell makes that needs to be shipped off, goes to this organelle (which modifies and packages).
Golgi Apparatus/Golgi Bodies
500
Cancer is caused by uncontrolled cell growth. Which one would most likely cause cancer? Bacteria, Crossing Over, or Mutations?
Mutations
500

True or False? The number of cells produced by meiosis is twice the number of cells produced by mitosis

True

500
Mitosis you do PMAT _____ times, but in meiosis, you do PMAT __________ times.
Once, twice
500
The cell spends most of its time in what phase of the cell cycle?
Interphase
