MITOSIS Flashcards
what are the importance of Cell cycle?
Cell growth
Cell repair
Cell duplication
are threadlike structures of DNA and protein that contains genetic information
Chromosomes
In which stage of the cell cycle are chromosomes replicated?
S phase
Which phase of the cell cycle is the longest?
Interphase
Which phase of the cell cycle is the shortest?
Mitotic Phase
is the preparatory phase
Interphase
is the dividing phase
M Phase
also called body cells
Somatic Cells
what is the difference between somatic cells and gamete?
Somatic- Mitosis/ Diploid cells
Gamete- Haploid Cells
define diploid cells
2 sets of chromosomes
define haploid cells
1 set of chromosomes
How many chromosomes made up a human/?
haploid- 23
diploid- 46
A condition in which a child is born with an extra copy of their 21st chromosome
Trisomy 21
is the division of a cell into two daughter cells that are genetically identical to the parent cell.
Mitosis
form a spindle of microtubules,
Centrioles
the chromatin materials start to condense, forming discrete chromosomes. The nucleus and other organelles of the cell start to disintegrate. Centrioles start to move toward the opposite pole
Prophase
Metaphase
chromosomes convene on the
metaphase plate
What is Metaphase Plate?
an imaginary plane equidistant
between the two poles of the spindle fibers
the sister chromatids are separated simultaneously at their centromeres. Spindle fibers will then pull the chromatids toward the opposite poles of the cell. Along with that action is the formation of spindle fibers between the migrating chromatids which causes the cell to elongate
Anaphase
The chromosomes have reached the
opposite poles of the cell. The spindle fibers start to disappear. Nuclei and cytoplasmic contents of the daughter cells start to reform.
Telophase
