Mitosis Flashcards
(18 cards)
What does cell division allow?
It allows organisms to replace dying or damaged cells
What is mitosis?
Mitosis is the process of cell division. It produces two identical daughter cells from one original cell.
What is mitosis for?
Growth and repair
What is meiosis for?
The production of sex cells.
What happens in mitosis?
One cell splits in half to create two new cells. The cell that divides is called the parent cell, and the two new cells are called daughter cells.
Are daughter cells similar?
Daughter cells are genetically identical to each other, and they are identical to the parent cell.
What happens during the cell cycle?
The daughter cells grow and divide, producing new daughter cells. Each single cell that divides turns into 2 separate cells.
What happens during interphase?
During interphase, the cells are all jumbled together inside the nucleus.
How many strands of DNA in most human cells?
There are 46 separate strands of DNA in most human cells. These are called chromosomes.
What does each daughter cell need?
A complete copy of DNA to function and grow properly.
What happens when each chromosome is copied?
When each chromosome is copied, the new strand of DNA remains attached to the old one in a single bundle.
What happens when the new strand of DNA is attached to the old one on a chromosome?
The number of chromosomes remains the same, but each one changes from single-stranded to double-stranded.
When does a cell make a complete copy of its DNA?
During interphase
Why does the cell’s DNA need to be copied before cell division can take place?
Because each daughter cell needs its own copy to grow and function
What are the four stages of mitosis? (PMAT)
Prophase, Metaphase, Anaphase, Telophase
Which stage of mitosis where the chromosomes line up along the middle of the cell?
Metaphase
Which stage of mitosis where two nuclei form?
Telophase
Which two stages of mitosis where the chromosomes are single-stranded?
Anaphase and Telophase
