Mitosis Meiosis Flashcards
Double helix, long strand genetic material
Dna
Granular form of DNA & Protein
Chromatin
ighly condensed DNA
Chromatid
Two Identical copies of chromatids
Sister chromatids
sister chromatids connected at
centromere
Chromosone
Pair of identical chromosone
Homologus chromosone
Fastens chromatids
Centrosome
Attachment for spindle fibers
Kinetochore
Sequence of bases in the life of a cell
Call cycle
Duration of my mitotic cell cycle
12-24 hours
Resting, arrested
G0
Phase 1
Interphase
46 chromatin, growth
G1
G1 time
6 hrs
Chromatin replicated 92, centrosome replicated 92
S
Chromatins to chromatids, prepare for mitosis
G2
Uses of mitosis
For growth repairing of body in the sexual reproduction and maintenance of chromosome number from parent to daughter cells and two identical daughter cell production
True or false… Mitosis is for all cells
False, it is for somatic cells only
Which is which… Mitosis, meiosis-Sexual reproduction asexual reproduction, identical not identical
Mitosis is for a sexual reproduction and identical in meiosis is not identical in for a sexual meiosis is for sexual reproduction
Chromatin to chromosomes
Prophase
Nuclear envelope disintegrate in the nucleolus disappear
Bruh face
Centrosome moves to poles, spindle apparatus
Prophase
Moves in organizes chromosomes during cell division
Bro face
Chromosomes lineup in metaphase plate
Metaphase
Chromosomes to sister chromatids
Anna face
What helps the chromatids pulled apart toward the end of the pole
Centrosome
Chromatids are pulled apart the word the pole
Anna face
Chromatids arrive at the pole of cellw
Teloface
What is karyokinesis and when does it happen
Cardio kinetics is the division or formation of nucleolus reappearing of nucleus and nuclear envelope spindle fiber disassemble and warm cleavage furrow which is the start of cytokinetic it also happens in the telophase
When does the cleavage furrow form
End of telophase and start of cytokinesis
When does the division of cytoplasm happen
Cytokinesics
Gaps zero resting gap one cell growth synthesis DNA replication gap to checkpoint that was the interface
A type of reproduction that uses gametes and combines genetic information of two individuals of different sex cells
Sexual reproduction
Haploid reproductive cell sex cells such as sperm cell and egg cell
Gametes
Union of egg sperm
Fertilization
Diploid vs haploid
Diploid – refers to the having single set of chromosomes
• 2n = 46 chromosomes
• Paternal and maternal origin
Haploid – refers to the having single set of chromosomes
• n=23 chromosomes
• From gametes
Cell division that results in the production haploid gametes
Meiosis
production and increase number of sex cells
Gametogenisis
– the process in which cells undergo meiosis to form gametes
Gametogenesis
stem cell / undifferentiated cell of spermatozoa
Spermarogonium
stem cell / undifferentiated cell of ovum.
Oogonium
Divides by mitosis during puberty
Interphase
Will undergo growth and development
and will be called primary spermatocyte /oocyte will divide via meiosis
Meiosis
Interphase of mitosis- same as meiosis
