1) the two original strands of the DNA molecule can be separated by ______
2) the enzyme ______ reads each template strand and adds

-heat
polymerase
complementary
nucleotides

6

from the STRs used in a forensic investigation, which STRs on which chromosomes would be particularly useful in determining

-?

7

a protein is made up of a chain of what

-amino acids

8

_________ amino acids tend to be found folded inside a protein, whereas _______ amino acids interact with water on the outside of the protein

-hydrophobic; hydrophillic

9

what determines a proteins function?

-the 3d shape of protein

10

what determines how a protein folds?

-the interaction of the side chains of each amino acid

11

____on mRNA interact with ____on tRNA to allow the _____to connect amino acids in the correct order during translation

-codons
anticodons
ribosomes

12

which of the following series has the stages of mitosis in the proper order

prophase
metaphase
anaphase
telophase

13

what would be the result if a cell completed interphase and mitosis but failed to complete cytokinesis

-you would have only one cell you would have twice as many chromosomes as the parents cells

14

a normal cell that sustains irreparable DNA damage will most likely ______

- die by apoptosis

15

which checkpoint prevents a normal cell from completing its cell cycle if it has not accurately replicated it DNA

-interphase at g2 M

16

which is the best definition of cancer

-
a disease in which unregulated cell division occurs

17

cell cycle checkpoints are present to ______

-

18

when your skin cells are exposed to UV light such as in a tanning bed, DNA damage can occur. of one of these severely UV irradiated skin cells is given a signal to divide, what are plausible outcomes?

- the cell will go through apoptosis after the damage occurs

19

why would the cell make apoptosis the default mechanism when a problem in the cell cycle is detected?

-makes sure the cells die instead of leading to cancer

20
