The synthesis of nucleotides requires several amino acids. Sort each amino acid as a precursor in the synthesis of purines, pyri
midines, both purines and pyrimidines, or neither purines nor pyrimidines. Note: If you answer any part of this question incorrectly, a single red X will appear indicating that one or more of the phrases are sorted incorrectly. Purines Pyrimidines Both NeitherA. leucine B. lysine C. methionine D. glutamine E. glycine F. histidine G. aspartate H. alanine I. tryptophan
Glycine is required for purines, aspartate for pyrimidines, glycine and aspartate for both purines and pyrimidines. The remaining amino acids are not required for the synthesis.
Explanation:
Nucleotides are the monomer for the synthesis of DNA and RNA. The two main class of nitrogenous bases are purines and pyrimidines. These nitrogenous bases require the amino acids as a precursor for their synthesis.
Glycine is the simplest amino acid and required for the synthesis of purines. Aspartate is required for the synthesis of pyrimidines. Glutamine and aspartate are required for the synthesis of both purines and pyrimidines. Lysine, leucine, alanine, histidine, methionine, tryptophan and alanine are not used as a precursor for the nucleotides.
Chlorphyll is not any of the listed biomolecules, but it is most closely related to carbohydrates as it contains Carbon, Hydrogen, and Oxygen. Chlorophyll is actually a pigment that absorbs light
Adapting is when the organism slowly changes as each generation goes by because the organism more suited for the environment is going to survive and reproduce while others will have a harder time and more than likely die off.
