The genetic code was originally deciphered, in part, by experiments in which synthetic polynucleotides with repeating sequences
AveGali [126]

Answer: a peptide containing alternating arginines and alanines.

Explanation:

As the mRNA has a repeating unit of CGCG.

Now if we extend the units with more CG (CGCGCGCGCGCG) the pairing will be as CGC-GCG-CGC-GCG. and if we see the amino acids coded by these codons are arginine for CGC and alanine for GCG.

As this synthetic mRNA doesn't require any initiation codon (AUG) thus the polypeptide will not have methionine, which is the first amino acid in every polypeptide coded by the initiation codon.

Thus, the synthetic mRNA will code for peptide having alternating arginines and alanines amino acids.

Answer:

the answer is selective permeability

Explanation:

A membrane that has selective permeability allows only substances meeting certain criteria to pass through it unaided. In the case of the cell membrane, only relatively small, nonpolar materials can move through the lipid bilayer (remember, the lipid tails of the membrane are nonpolar).
