Stages of Mitosis -Will
Centromere:
The middle of a chromosome
What happens in Prophase
The chromatin condense into chromosomes
True or False : Human Brain cells never divide
true
What are the 3 stages of the Cell Cycle?
:Interphase, Mitosis, Cytokinesis
What’s a sister chromatid?
Identical rods of the chromosome
Sister Chromatids:
The bottom end of the Chromosomes
What happens in Metaphase
The chromosomes line up in the middle of the cell
True or false:There are about 50 million cells dividing in your body right now
False, there are about 100 million
Why do cells need to make more cells? (Name 2)
Growth, Replace old and or dead cells, Replace damaged cells, or Certain animals can regenerate body parts
What does the centromere do?
Holds sister chromatids together.
Chromosome:
A structure that holds DNA that is found in eukaryotic cells
What happens in Anaphase
The chromosomes move to opposite sides of the cell
What is the longest phase of the cell cycle?
Interphase
True or false, When we grow, our cells get bigger.
False, when we grow we make more cells
What do spindle fibers do?
Attach to centromeres during metaphase and pull sister chromatids apart
Chromatin:
A relaxed form of DNA that makes up Chromosomes.
What happens in Telophase
Small Nuclear vessels for around the Chromosomes
Which phase of a cycle differs in plant and animal cells?
Cytokinesis
What are the phases of mitosis (names in order)
Prophase,Metaphase,Anaphase,Telophase
What’s chromatin?
Thin strands that contain DNA (during interphase)
Spindle:
A microtubule structure that separates the chromosomes during Mitosis
What happens in cytokinesis
The cell plate divides the cytoplasm and the cell splits
Why do cells go through mitosis
growth, repair, reproduction, replacement
What happens during telophase
2 nuclei are formed.
What’s the cell plates job?
To help break the cell apart
