Watson and Crick
Francis Watson and James D. crick published an article that described the discovery of the double helix structure of DNA . This article contains the answer to a fundamental mystery about living organisms .Also it explains how your genetics are passed down through generation to generation
Mitosis is a type of division that results in two daughter cells each having the equal amount of number and same kind of chromosomes as the parent nucleus.
Cell Cycle
What is DNA?
A series of steps in a cell leading to division and duplication. The cell cycle allows the organism to grow and replaces cells as they get worn out.
By: Elizabeth Carrillo, Maria Delgadillo, Stephanie Diaz, Greisy Ramirez
Definition: a stage of the cell cycle where there is no cell division going on and the cell obtains nutrients, and duplicates its chromosomes
The final phase of cell division
The chromatids or chromosomes move to opposite ends of the cell and two nuclei are formed
The chromosomes move away from one another to opposite poles of the spindle
The cytoplasmic division of a cell at the end of mitosis
Brings about the separation into two daughter cells.
It's the first stage which the cell division
The chromosomes become visible as paired chromatids and the nuclear envelope disappears
Second stage
The chromosomes become attached to the spindle fibers.
Deoxyribonucleic acid
Self-replicating material present in nearly all living organisms
In the nucleus
DNA molecule is tightly packed- called a chromosome
Carried through genetics
Nearly every cell in a person's body has the same DNA
When the cell is damaged or disrupted there might be a factor for cancer. As the cell goes through mitosis, it has to pass many checkpoints to make sure it's mutating correctly. If one is missed or even damaged this may pose a risk for cancer.
