Heredity&Genetics
Question | Answer |
---|---|
Genes | A set of instructins that determine your characteristics; Each gene carries a seperate piece of information |
DNA | Deoxiribo Nucleic Acids; contains a code of instructions passed from parent to offspring that must be accurately duplicated before being passed on; genetic material of the cell which is contained within the nucleus |
Mutation | changes in DNA that occur in gametes (sex cells) that may be passed on to offspring |
Selective Breeding | intential mating of two organisms to produce an offspring with desirable characteristics or eliminate a specific trait |
Heredity | the passing of genetic instructions from one generation to the next |
The Gene Chromosome Model | DNA is in genes which are in chromosomes which are in cells which are in the body |
Asexual reproduction | All genes come from a single parent; making the offspring genetically identical to the parent |
Mitosis | cell division |
Natural Selection | the process by which forms of life having traits that better enable them to adapt to specific environmental pressures, as predators, changes in climate, or competition for food or mates, will tend to survive rather others of its kind. |
Cancer | uncontrolled mitotic cell division |
What are the four nitrogenous bases of DNA? | Adenine, Guanine, Cytodine, and Thymine |
