interphase

Question 1

what occurs in interphase

Answer 1

the cell prepares to divide

Question 2

Interphase (G1)

Answer 2

growth phase one: assembly of carbs, lipids and proteins, protein called kinase activates

Question 3

DDI in G1

Answer 3

-density dependent inhibition: tells cells to divide and fill in gap or stop dividing
-Cell division: protein Kinase (activates other proteins/ uses ATP) and where errors are corrected before continuing

Question 4

Interphase (S)

Answer 4

synthesis: DNA within nucleus gets copied

Question 5

Interphase (G2)

Answer 5

growth phase 2: doubling of cytoplasm; more protein produced

Question 6

Histones

Answer 6

Protein which winds up DNA, forms chromosomes (in G2)

Question 7

Benign tumor

Answer 7

noncancerous; localized abnormal tissue like a mole

Question 8

Malignant tumor

Answer 8

cancerous tissue; abnormal tissue that spreads to other parts

Question 9

Metastasis

Answer 9

spread of cancer from where tumor first started to somewhere else through circulatory or lymphatic system

Question 10

Angiogenesis

Answer 10

formation of blood vessels around tumor which allows tumor to spread

Question 11

carcinoma cancer

Answer 11

found in organs and glands (epithelial tissue)

Question 12

Sarcoma cancer

Answer 12

found in bone, muscle, fat and cartilage (connective tissue)
-most painful

Question 13

Leukemia and Lymphoma cancer

Answer 13

blood cancers

Question 14

Melanoma

Answer 14

skin deadly

Question 15

diff. between cancer and normal cells

Answer 15

-loss of contract inhibition
-loss of intercellular junctions (no attachment so it spreads)
-indefinite division
