Mitosis Flashcards
There are two types of cells in the human body
Somatic cells(body cells) and sex cells/gametes(female egg and male sperm
Definition of mitosis
It is the process where a single parent cell divides to form 2 identical daughter cells. The two daughter cells are not only identical to each other but also to the original mother cell and has identical number of chromosomes. They have the same genetic material in their cell nuclei as in the nucleus of the mother cell.
The process of cell division where gametes are formed is known as
Meiosis
True or False: Bacteria create daughter cells
True. Bacteria, while they lack the membrane bound organelles of eukaryotes, still need to grow, sort their resources, and divide their cell membrane. They must also copy, separate, and distribute their DNA into the daughter cells
Function of the mitosis process
It ensures that the organism grows and increases in size. Ensures that the worn out or damaged cells are repaired and animals. It results in asexual reproduction in some simple plants and animals
Chromosomes
Are thread like structures found in the cell nucleus of virtually all cells. It transfers hereditary characteristics from generation to generation.
When the cell is not dividing
The chromosomes appear as a mass of threads the chromatin network. When the cell is dividing the chromatin network condenses, the threads become shorter and thicker and visible as single stranded chromosomes
A chromosome consists of
The nucleic acid DNA that is wrapped helically around proteins known as histones.
There are various DNA segments known as
Genes along the length of each chromosome. Each gene control a specific hereditary characteristic.
