Definition
-word used when DNA strand matches up with mRNA -base language -same language |
|
|
Term
|
Definition
-base language is converted into protein language -from mRNA to proteins |
|
|

Term
| Natural Selection Conditions |
|
Definition
1. More offspring produced in a population than can possibly survive 2. Individuals in population vary in their characteristics (random mutations, gene duplication) 3. Some of this variation is heritable 4. Individuals in population must vary in biological fitness (competition) 5. Environment determines which individuals have higher biological fitness based on characteristics they inherited |
|
|
Term
|
Definition
-more than one physical type is successful -makes an M-shaped graph -example: Sun Fish |
|
|
Term
|
Definition
-variation is reduced -graph gets higher and skinnier -example: room with water and people |
|
|
Term
|
Definition
-one variation has the most fitness -graph shifts towards that side and is skewed to the other side -example: bull frog |
|
|
Term
| Evolution by Genetic Recombination |
|
Definition
-genetic material from each kind can intermix -example: flu |
|
|
Term
| Evolution by Genetic Drift |
|
Definition
-change by random mutations -not so much leaning to adaptation -example: HIV/AIDS |
|
|
Term
|
Definition
-genes in organisms that have become nonfunctional -it is recognizable by its fragmented parts -will eventually erode away -provide links to distant ancestors and former ways of life |
