Igoryamba

Answer:

A. Repeats of "Alanine-Arginine"

B. Repeats of "Tyrosine-Isoleucine"

C. Repeats of Aspartic acid

Explanation:

A. The synthetic RNA with GC repeats would have repeats to two codons: GCG and CGC which in turn code for alanine and arginine amino acids respectively.  Hence, its polypeptide would have repeats of "Alanine-Arginine"

RNA: GCG CGC GCG CGC GCG CGC  

Alanine-Arginine-Alanine-Arginine-Alanine-Arginine-Alanine-Arginine ...

B. The synthetic RNA with UA repeats would have repeats to two codons: UAU and AUA which in turn code for tyrosine and Isoleucine amino acids respectively.  Hence, its polypeptide would have repeats of "Tyrosine-Isoleucine"

RNA: UAU AUA UAU AUA UAU AUA

Tyrosine-Isoleucine-Tyrosine-Isoleucine-Tyrosine-Isoleucine-Tyrosine-Isoleucine

C. The synthetic RNA with GAC repeats would code for polypeptide of aspartic acid only as GAC codes for aspartic acid.

RNA: GAC GAC GAC GAC GAC GAC
