Describe the structural differences between dna and rna.

Explanation:

DNA is a double helical structure. It is a long polymer molecule which has deoxyribose sugar and phosphate backbone. It have four nitrogenous bases which are supported by the phosphate backbone. These are the adenine, guanine, thymine and cytosine.

RNA is a single stranded molecule. It is a polymer with a ribose sugar and phosphate backbone. It also exhibit four nitrogenous bases that are supported by phosphate backbone these are adenine, guanine, cytosine and uracil.

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.
