Chromosomes And Mitosis Flashcards
What form is DNA in?
Long strands of DNA
What does it mean when a cell wants to divide?
When a cell wants to divide it condenses it’s DNA into chromosomes.
How could chromosomes affect people?
It can give then Down syndrome.
What is the cell cycle?
Growing
Replicating DNA
Dividing (mitosis)
What is exponential growth?
Where the cells double over many generations.
What is GDCMPTD
Growth
DNA replication
Condense chromosomes
Middle
Pull apart
Two nuclei
Divide
Explain the process of the cell cycle.
Growth and DNA occur. Organelles duplicating. DNA in threads.
DNA condensed into chromosomes and nucleus breaks down.
Chromosomes line up in the middle and fibres pull them apart.
two new nuclei form round chromosomes.
Cytoplasm and cell membrane divide to five 2 identical daughter cells.
How do you work out the real width of a cell?
Real size = image size/ magnification
Why do human skin cells need to divide?
To repair wounds or cuts.
How can someone know whether a cell is undergoing mitosis?
You can see the x shaped chromosome.
You can see the two arms of the chromosome being pulled apart.
