bio mitosis

Question 1

the union of gametes from two individual organisms resulting in a fertilized egg or zygote

Answer 1

fertilization

Question 2

is an orderly sequence of events that describes the stage of a cell’s life from the division of a single parent cell to the production of two new daughter cell

Answer 2

cell cycle

Question 3

is the part of the cell cycle that results in identical daughter nuclei that are also genetically identical to the original parent nucleus

Answer 3

Mitosis

Question 4

the two major phases of the cell cycle

Answer 4

interphase
mitotic phase

Question 5

during this phase the cell grows and DNA is replicated

Answer 5

interphase

Question 6

the three stages of interphase

Answer 6

G1
S
G2

Question 7

-in this stage of interphase the cell grows and more organelles are produced
-the cell is active at the biochemical level
-the cell is accumulating building blocks of chromosomal DNA , proteins and energy reserved

Answer 7

G1 Phase (First Gap)

Question 8

-this stage of interphase where DNA replication proceeds that results in the formation of identical DNA molecules-sister chromatids- that are joined by the centromeric regions
-centrosome is duplicated

Answer 8

S Phase (Synthesis of DNA)

Question 9

-this stage of interphase, the cell replenishes energy stores and synthesizes proteins needed for chromosome manipulation
-organelles are duplicated
-cytoskeleton is dismantled

Answer 9

G2 Phase (Second Gap)

Question 10

this phases is a multistep process in which the duplicated chromosomes are condensed, aligned, separated and moved to opposite poles of the cell, and divided into identical daughter cells

Answer 10

Mitotic Phase

Question 11

cells in this phase are not actively preparing to divide, the cell is inactive

Answer 11

G0 Phase

Question 12

is one of several points in the eukaryotic cell cycle at which the progression of a cell to the next stage in the cycle an be halted until conditions are favorable

Answer 12

cell cycle checkpoint

Question 13

The three main cell cycle checkpoints:

Answer 13

near the end of G1
at G2/M transition
during metaphase

Question 14

-cell checkpoint where the cell irreversibly commits to the cell division process
-checking for genomic DNA damage, cell size, and protein reserves

Answer 14

G1 Checkpoint

Question 15

this checkpoint is to ensure that all of the chromosomes have been replicated and that the replicated DNA is not damaged

Answer 15

G2 Checkpoint

Question 16

-this checkpoint occurs near the end of metaphase stage of karyokinesis
-known as the spindle checkpoint, as it determines whether all sister chromatids are correctly attached to the spindle microtubules

Answer 16

M Checkpoint

Question 17

also known as mitosis, that is divided into a series of phases that results in the division of the cell nucleus

Answer 17

karyokinesis

Question 18

is the second main stage of the mitotic phase during which cell division is completed via the physical separation of the cytoplasmic components into two daughter cells

Answer 18

cytokinesis
