Mitosis
What is Mitosis?
Division of the nucleus
What are the ends of chromosomes called?
Who coined the term "cell"
Robert Hooke
What phase is the resting phase?
Interphase
What are the cells called that regenerate limbs?
Stem cells.
What is the order of phases in mitosis?
Prophase, Metaphase, Anaphase, Telophase
What is DNA?
Genetic material that determines an organism's inherited characteristics and provides information for growth of each cell.
Who concluded that all animals are made of cells?
Theodor Shwann
What happens in synthesis phase?
DNA is replicated.
Why do cells divide?
Cells divide so that they can process things faster.
What happens during prophase?
Chromosomes condense and the nucleus breaks down.
How would telomerase research apply to research of slowing down the aging process?
Maintain cells and keeps the brain healthy. Prevents memory loss.
Who co-founded the cell theory and discovered plants are made of cells?
Matthias Jakob Shleiden
What happens at G1 Phase?
Cell grows, carries out normal functions, and replicates the cells organelles.
What activates kinases?
Cyclins.
What are centrioles?
Cylinders made of short microtubules
How many chromosomes are in each human body cell?
46 chromosomes
Who invented the microscope?
What happens at G2 Checkpoint?
The DNA must have been replicated correctly and cell needs to be big enough for cell division.
What is apoptosis?
A programmed cell death.
What mechanism ensures that each cell receives an identical set of DNA during mitosis?
Synthesis (S) phase
How long is DNA in one cell?
10ft long
Who was the first to look at bacteria through a microscope and help disprove spontaneous regeneration?
Antonie Van Leeuwenhoek
What is the G0 (zero) stage?
Cells that don't regularly divide and can stay in this stage permanently or temporarily.
What are some external factors for regulating cell division?
Physical signals and chemical signals.
