Mitosis Flashcards
What is the Cell Cycle
Cell Cycle: regular pattern of growth, DNA duplication and cell division in eukaryotic cells
G1: Cell growth, carry out normal functions, and replicates their organelles
S: DNA synthesis
G2: Additional growth
M: Cell division
Cell cyce, G1, S, G2, M
What is Interphase
The cell copies its DNA and grows in preparation for division. DNA is loosely organized during interphase
where DNA is doubled
Thin “threadlike” structures that pull cromatids apart during mitosis
Spindles
What is Mitosis needed for
Repair, growth, and replacement
Mitosis is the division of what?

when cancer cells spread beyond their original site
to other parts of the body
What is a Carcinogen
substance that produces or promotes the development of cancer
What phase is a eukaryotic cell in for 90% of its lifetime
Interphase
what usually happens during the cell cycle of a cancerous cell
cell growth is not controlled
