1. Which statement about site-directed in vitro mutagenesis is false? A. Point mutations can be created by making the change in 1 of the primers and having the primers (facing away from each other) extend around the whole plasmid.

B. Deletions can be created by having the 5' ends of the primers separated by the region you want deleted, therefore it won't be amplified during PCR.

C. Insertions can't be made because you can't add extra DNA to the primers used to amplify the plasmid.

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.

emerging idea only occurs as a raw idea that could appear out of nowhere. meanwhile, to reach scientific consensus , that idea must be structured and tested over and over again through various experiments. the scientific consensus transforms the raw idea into idea that is more reliable through the process of scientific elimination.
