Answer:
RNA resembles a long chain with the links in the chain made up of individual nucleotide. RNA carries out the instructions encoded in DNA, most biological activities are carried out by proteins. The accurate synthesis of proteins thus is critical to the proper functioning of cells and organisms. The linear order of amino acids in each protein determines its three-dimensional structure and activity.For this reason, assembly of amino acids in their correct order, as encoded in DNA, is the key to production of functional proteins. Three kinds of RNA molecules perform different but cooperative functions in protein synthesis. Synthesis of all protein chains in prokaryotic and eukaryotic cells begins with the amino acid methionine. In most mRNAs, the start (initiator) codon specifying this amino-terminal methionine is AUG.In a few bacterial mRNAs, GUG is used as the initiator codon, and CUG occasionally is used as an initiator codon for methionine in eukaryotes. The three codons UAA, UGA, and UAG do not specify amino acids but constitute stop (terminator) signals that mark the carboxyl terminus of protein chains in almost all cells.The sequence of codons that runs from a specific start site to a terminating codon is called a reading frame. This precise linear array of ribonucleotides in groups of three in mRNA specifies the precise linear sequence of amino acids in a protein and also signals where synthesis of the protein chain starts and stops.

Answer:
In August, prominent physician Benjamin Rush, signer of the Declaration of Independence, long considered the father of American medicine, described an “unusual number of bilious fevers, accompanied with symptoms of uncommon malignity.” He concluded that, “All was not right in our city.”
The correct answer is sought to avoid involvement in European <span>political struggles
They were isolationists and believed that the United States should care only for its own well-being. For example, Monroe did this through the Monroe doctrine which established that if any European nation tried to colonize any country in the Americas that the Americans would go to war to prevent them and send them back to Europe.</span>

Explanation:
Similarities between Japanese and European feudalism include a social system of various classes with little possibility of mobility from one class to another, the proffering of allegiance in exchange for protection, a warrior class with a code of honor and a peasant class tied to the land. Both societies also had clergy that functioned outside the normal feudal system.
