Yonko Biological Levels Of Organization

Meiosis – A process by which sex cells (gametes) are produced. Reduces the chromosome number by half, which is then restored (the full chromosome number) during fertilization.
Accessory Organs – A group of organs involved
in the digestive system
but do not have food
passing through them
Chemical reaction – A process in which one or more reactants is changed into 1 or more new products. Involves the rearrangement of atoms, not the creation or destruction of them. Burning paper, for example.
Transduction – The process in which infection by a virus results in DNA being transferred from one bacterium to another
functional group – A specific configuration of atoms commonly attached to the carbon skeletons of organic molecules and usually involved in chemical reactions.
Histone – a small protein that associates with DNA to form a nucleosome
Kristi is doing leg extensions at the gym, what physiologic mechanism will occur in her quadriceps?
1. proteins are assembled by ribosomes on the rough ER 2. vesicles transport proteins to the Golgi apparatus 3. golgi modifies the protein and packages them in new vesicles 4. vesicles releases proteins that have destinations outside the cell 5. vesicles containing enzymes remain inside the cell – protein synthesis
fermentation – in the absence of oxygen releases energy from food molecules by producing ATP

restriction enzyme – A degradative enzyme that recognizes and cuts up DNA (including that of certain phages) that is foreign to a bacterium.
tissue – a group of similar cells that perform a common function
stimulus – (1) In the context of a nervous system, a factor that triggers sensory transduction. (2) In behavioral biology, a factor that triggers a specific response.
