Mitosis

Question 1

Interphase

Answer 1

Cell prepared to divide
Dna is replicated
Organelles replicated
Increased ATP production

Question 2

Prophase

Answer 2

Chromosomes condense
Centrioles move to opposite ends of the cell forming spindle fibres
Nuclear envelope breaks down

Question 3

Metaphase

Answer 3

Chromosomes line up along the cell and become attached to the spindle by the centromere

Question 4

Anaphase

Answer 4

Centromere divides
Sister chromatids seperate
Spindles contract and pull chromatids to opposite poles

Question 5

Telophase

Answer 5

Chromatids reach opposite poles and uncoil to become chromosomes
Nuclear env reforms

Question 6

Cytokinesis

Answer 6

Cytoplasm divides
Forms two identical daughter cells

Question 7

Binary fission

Answer 7

Circular DNA and plasmids replicate
Cell gets bigger and DNA loop moves to opposite poles
Cytoplasm starts ti decide
Cytoplasm divides and daughter cells produced
Each cell has one copy of circular DNA

Question 8

How do viruses replicate

Answer 8

They use attachment proteins to bind to receptors that are on host cells
They inject they’re DNA or RNA into host cell and then the cell replicates the viral particles
