Intro to Cell Cycle

Duplicated the DNA

Completes cell division

Maintain genetic homeostasis

Synthesizes new molecules

True

False

Mutations can cause uncontrolled cell division which causes cancerous cells to spread rapidly and take nutrients from healthy cells.

Cancer stops cell division from happening.

Cell division causes viruses that spread around the body and cause cancer.

Cancer is not related to cell division.

to increase the speed of aging

to cause wounds and damages

to repair wounds and damages

to make more energy

DNA helicase is unwinding a segment of DNA into two separate strands.

DNA polymerase is proofreading the new DNA strand

DNA helicases are exchanging sections, which will then be rejoined.

DNA polymerase is adding new nucleotides to the 3′ end of the RNA primase.

Homologous chromosomes are irrelevant to genetic stability and errors in separation have minimal impact.

Homologous chromosomes ensure accurate DNA replication; errors in their separation can lead to genetic disorders like trisomies.

They prevent genetic recombination, so errors increase genetic diversity without negative effects.

Their role is purely structural, affecting only the physical appearance of chromosomes, not genetic content.

The cell still has a nuclear membrane and the DNA is relaxed in the form known as chromatin

The cell's nuclear membrane is disappearing and the DNA is condensed in the form known as chromosomes

variable shape and size of cell

arranged in an organized manner

cells have large, variably shaped nuclei

uniform size and shape of cells
