interphase
- longer phase of cell cycle
interphase
- with high metabolic activity and the DNA replication happens.
prophase
- the time where the chromosomes condense and the nuclear envelope breaks down
interphase
- the time of the growth and development of the cells where organelles are being developed.
interphase generally last at least
12 to 24 hours
in mammalian tissues.
What are the stages in interphase?
G1
,
S
,
G2
How many chromatids are in chromosomes?
2 chromatid
What is in the middle of chromosomes that joints the two chromatids?
Centromere
What stage of cell cycle when the
centrioles
move towards the opposite ends and the
spindle fibers
extend between the centriole pairs.
metaphase
- the chromatids alignment along the equator of the cell, called the
equatorial plane
What is the shortest phase of mitosis?
anaphase
anaphase
- chromosomes are separated by a structure called a
mitotic spindle
telophase
- wherein the chromosomal movement stops and nuclear envelopes and the nucleoli form.
cytokinesis
- the division of the cell's cytoplasm and organelles. Formation of cleavage furrow.
kinetochore
- this is where the microtubules hook itself to align the chromosome
