..... The concentration of three different aminoacyl-tRNA synthetases, associated with three different amino acids, are found in much lower than normal concentrations in the cytosol of an animal cell. In your own words, describe how this may impact the rate of A) translation, and B) the citric acid cycle. Explain your reasoning for each. Please clearly label your responses as A) and B).

Common proteins are polymers of 20 different amino acids. How many amino acids are necessary for a protein polymer to have at least as many possible different sequences as there are atoms in the Universe? (There are about 2 × 1056 moles of atoms in the Universe.) *Note - The answer is a mathmatical answer. I need an explanation of the math behind this problem.

You mix all the required elements for translation, charged tRNA with amino acids, ribosomal subunits, and mRNA etc., in a test tube. Given that the mRNA has the following sequence, what is/are the polypeptide(s) that could be produced (ignore the lack of start and stop codons) 5' - AGCAGCAGCAGCAGCAGCAGC-3" A. Poly-Ser. B. Poly-Gin. C. Poly-Arg. D. Poly-Met. E. Multiple of the above would be produced.
