Studied by 5 peopleVital life processes that require mitosis
Regeneration, development, asexual reproduction, and wound healing
Difference between a haploid cell and a diploid cell?
Haploid has one copy and diploid has two copies
What are the haploid and diploid numbers in humans?
N=23, 2N=46
What are the three parts of interphase?
G1, S, G2
G1
Cell grows larger
S
Cell stops growing and DNA replication occurs
G2
Cell continues to grow
What is G0?
Cells that don't make copies of themselves
A cell spends most of its time in which phase?
Interphase
One side of a chromosome is a...
Chromatid
The middle of a chromosome is the...
Centromere
Chromosomes have short and long...
Arms
Chromosomes have two chromatids after they have passed through the ______ phase
S
Prophase
The nucleoli a disappears, chromatin condenses into chromosomes, separation of centromeres occurs, and the formation of the mitotic spindle
Pro Metaphase
The nuclear envelope disassembles, chromosome forms two Kinetochores at the centromere l, and microtubles attach to the centromere
Metaphase
Chromosomes align in metaphase plate; meet in the middle
Anaphase
Chromatids separate towards opposite poles; move apart
Telophase
New nuclear envelope forms, chromosomes unfold back into chromatin, nucleoli reappears, cell continues to enlogate
Cytokinesis
Daughter cells divide
Mitosis in plants vs. animals
Instead of "zipping" in half, plants have to build a cell plate in between the cell because of a cell wall
What disease results from cells reproducing out of control?
Cancer(tumors form)
How are the frequencies of smoking and lung cancer related?
Chemicals found within can cause mutations and cause cells to jump in and become cancerous; cells reproducing out of control
