unit 10

Question 1

Rna primase

Answer 1

polymerizes (to create a polymer) RNA primer in 5’ to 3’ direction, with replication bubble
What gets the dna replication started

Question 2

Dna polymerase III

Answer 2

synthesizes/creates new dna single strand by adding dna nucleotides using template strand

Question 3

Dna polymerase I

Answer 3

replace rna primer with new dna, polymerized in 5’ to 3’ direction; on lagging strand

Question 4

helicase

Answer 4

unwinds the double helix of dna into two separate, single strands

Question 5

rna primer

Answer 5

made of rna nucleotides, necessary for dna polymerase 3 to latch on to and begin to do its job

Question 6

cancer

Answer 6

uncontrolled cell growth

Question 7

checkpoints

Answer 7

times during the cell cycle cycle where the cell pauses and checks on certain things (size, synthesis of DNA molecules)

Question 8

tumor

Answer 8

large conjunction of highly dense cells

Question 9

metastasis

Answer 9

when cancer cells spread

Question 10

why is mestasis bad?

Answer 10

a tumor could develop because of the excess of cells. Mestasis could also result in the death of healthy cells due to the lack of space for them
