Just because ONE chimpanzee used tools, doesn't mean ALL chimpanzees use tools. You need to observe way more than one chimpanzee to conclude that they ALL do that thing. For example, if I saw one monkey eating honey, I can't conclude that ALL monkeys eat honey.
Answer:
The air is really a mixture of many different gases, and each gas has its own properties. The composition of air is not constant. It can vary from time to time and place to place.
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.

When a hairpin loop forms in the nascent mRNA: The hairpin will destabilize the interaction and possibly lead to transcriptional termination.
Transcription in prokaryotes like E. coli is terminated either by a rho-dependent process or a rho-independent process. Intrinsic termination is controlled by the specific sequences of RNA .
When the termination process starts, the transcribed mRNA forms a stable secondary structural hairpin loop, also known as a stem-loop. Several uracil nucleotides follow this RNA hairpin. The uracil and adenine connections are exceedingly weak. NusA, a protein attached to RNA polymerase, attaches to the stem-loop structure so firmly that it momentarily stalls the polymerase.
The polymerase is pausing at the same time that the poly-uracil sequence is being transcribed. The RNA-DNA duplex can unwind and separate from the RNA polymerase because the weak adenine-uracil interactions reduce the energy of destabilization for the RNA-DNA duplex. Overall, transcription is terminated by the modified RNA structure.
