BIOLOGY Flashcards
It’s the process by which a cell divides to
form two new cells
CELL DIVISION
Binary Fission
Three (3) major steps;
DNA Replication, Chromosome Segregation, Cytokinesis (Separation)
Cell division that results in two daughter cells
each having the same number and kind of
chromosomes as the parent cell.
EUKARYOTIC CELL DIVISION
MITOSIS
Two (2) main steps:
Mitosis, Cytokinesis
Fours steps; MITOSIS
[Prophase>Metaphase>Anaphas
e>Telophase]
Cytoplasm divides forming two
new daughter cells
Cytokinesis
Each daughter cell is NOT Genetically Identical
to parent cel
MEIOSIS
Each daughter cell is Genetically Identical
to parent cel
MITOSIS
The sequence of events from the time a cell
first arises as a result of cell division until the
time when that cell itself divides.
CELL CYCLE
Cell after division begins a new cycle
Consist of two(2) main periods;
I. Interphase
II. Mitotic Phase
period of growth and DNA replication
between cell divisions
Interphase
Interphase 3 PHASE
𝐺1 Phase, S Phase, G2 Phase
Cell increases in size in this phase
G1 Phase
Replication of DNA
S Phase
Two sister strands of DNA called
chromatids are produced in this phase
S phase
