DNA- is the material found in the nucleus that contains the genetic info. 4 billion codes in length Gene- a segment of DNA that controls a certain protein production. A gene is made up of hundreds to thousands of codes. Chromosomes- genetic material that is coiled up into structures during cell division. Importance of DNA- genes control the production of proteins..(look like, body function, body communications, and enzyme control) DNA screening- the process of testing individuals to determine whether they have the gene(s) associated w/ a disorder amniocentesis- to look at the chromosomes of a fetus

Mutagens- substance/factor that cause a mutation
Cell size- in order for materials to move in/out of cells they must be small. high surface area: volume ratio. the larger the cell..the longer diffusion Diffusion- when a substance spontaneously moves from an area of high [ ] to an area of low [] osmosis- when H2o moves across a selectivly permeable membrane from an area of high [ ] to an area of low [ ] cell reproduction- the general process by which new cells are formed cell division- the process by which a parent cell divides into 2 daughter cells mitosis- the process by which the duplicated contents of the cell's nucleus divide into 2 = parts (Prophase, Metaphase, Anaphase, Telophase) cell specialization- the process by which cells develop from similar cells into cells that have specific functions w/...
