neoplasia - CORRECT ANSWER ✔✔- disorder of altered cell
differentiation and growth
neoplasm - CORRECT ANSWER ✔✔- the new growth that occurs as a
result of neoplasia
proliferation - CORRECT ANSWER ✔✔- --process of increasing cell
numbers by mitotic cell division
differentiation - CORRECT ANSWER ✔✔- process in which cells
become more specialized with each mitotic division
cell cycle (figure 2.1) - CORRECT ANSWER ✔✔- G1 (first growth
phase)
S (DNA synthesis phase)
to G2 (second growth phase)
M (mitosis).
, G1 - CORRECT ANSWER ✔✔- (gap 1)
--DNA synthesis stops
--cell enlarges
--both RNA and protein synthesis begin
S phase - CORRECT ANSWER ✔✔- --DNA synthesis occurs
--produces two separate sets of chromosomes, one for each daughter
cell.
G2 - CORRECT ANSWER ✔✔- (gap 2)
--DNA synthesis again stops
--RNA/protein synthesis continues
--first three (G1, S, G2) phases are referred to as interphase
checkpoints - CORRECT ANSWER ✔✔- --Located at the end of each
of these phases (G1, S-phase, and G2)
--means of molecular surveillance used to ensure the cell is ready to
proceed to the next phase
--if not, the cycle is halted and allowed to complete its replication or
even repair any DNA damage (when detected), thereby ensuring all the
genetic information is passed on correctly.
M phase - CORRECT ANSWER ✔✔- --consists of mitosis (dividing up
the DNA) and cytoplasmic division
