Tor F 1.Where the enzyme RNA polymerase first binds to the DNA - promoter

T or F 2. The on-off switch - Regulator

T or F 3. Codes for specific proteins - Coding genes

T or F 4. A portion of DNA reverses itself. - Translocation

T or F 5. When mutations produce an extra part or copies of chromosomes.
Duplication

T or F 6. Doesn't code for anything, non-coding regions - Intron

T or F 7. Trp Operon - which determine the formation Ind arrangement of body parts in
multicellular organisms, control gene expression by regulation of - DNA translation T or F 8.

T or F 9. Coding regions on DNA or RNA, codes for proteins - Exon

T or F 10. An acquired mutation in a non-gamete cell; mutation exists only in the cell type that
spawns the mutation - Inherited mutation

c-reactive protein (crp) is an acute phase protein belonging to pentraxin family of proteins, whose levels increases 1000-fold or more in concentration in blood during the occurrence of an injury, inflammation or tissue death.

step 1: nitrogen fixation- conversion of atmospheric no₂ into forms useful to plants by lightning, bacteria, and cyanobacteria.

step 2: nitrification-process of converting ammonia to nitrite or nitrate.

step 3: assimilation-plant roots absorb new form of nitrogen.

step 4: ammonification-conversion of organic nitrogen to ammonia by bacteria involved in decomposition.

step 5: denitrification-bacteria turns the decomposed matter back into n₂o, which is released into atmosphere; repeat cycle.

when you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. this increases the space in your chest cavity, into which your lungs expand. the intercostal muscles between your ribs also enlarge the chest cavity. they contract to pull your rib cage both upward and outward when you inhale.
