Final answer:

The mRNA sequence 5'-AUGCCACGAGUUGAC-3' encodes for the amino acid sequence Methionine-Proline-Arginine-Valine-Aspartic Acid, demonstrating the Triplet Code in which sets of three nucleotides correspond to specific amino acids.

Step-by-step explanation:

The question relates to the process of translating a sequence of nucleotides in messenger RNA (mRNA) into a sequence of amino acids to form a protein, which is a fundamental aspect of molecular biology and genetics. The studies mentioned are presumably ones that provide evidence for the Triplet Code, which is the hypothesis that three consecutive nucleotide bases (codons) on mRNA correspond to one amino acid in a protein.

The sequence given, 5'-AUGCCACGAGUUGAC-3', can be split into codons and translated using the genetic code, which has been deciphered through various experiments that support the Triplet Code hypothesis.

Decoding the mRNA sequence provided:

  • AUG - Methionine (Start)
  • CCA - Proline
  • CGA - Arginine
  • GUU - Valine
  • GAC - Aspartic Acid

The amino acid sequence encoded by the mRNA is Methionine-Proline-Arginine-Valine-Aspartic Acid.
