How was genetics discovered? In the 1860s Gregor Mendel discovered "factors" that determined inheritance of traits in plants (notice how many great discoveries appear first from work on plants) By 1906, Thomas Hunt Morgan showed that ‘genes’ are the "factors" that Mendel had discovered, and that genes are located on chromosomes. Then in 1944 Oswald Avery showed that genes are made of DNA! (We have come a long way). We now have sequenced the genomes of:

step 1 ammonium can be absorbed by plants, but some is converted into nitrates which are better for plants to absorb. this is called nitrification. 2. step 2 the deer eats the plants and uses the nitrogen-containing proteins for cell growth. 3. step 3 bacteria in the soil conduct nitrogen fixation to convert nitrogen gas from the atmosphere into ammonium. 4. step 4 some of the nitrates are absorbed back into plants, but denitrification breaks down the nitrates into nitrogen gas released back into the atmosphere. 5. step 5 nitrogen is found in the urine, which gets broken down into ammonium through the process of ammonification. 6. step 6 plants absorb the ammonium and begin assimilation, the process to add the nitrogen to protein.
