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.

The correct answer is D. Food Shortages.
Answer:
Demetrius
Explanation:
A man named Demetrius, probably the leader of a regional guild of silversmiths, called together not only his guild but also those in related trades. The silversmiths made a tremendous profit from selling silver shrines of the goddess Artemis.

Well, the Western Cherokees perpetrated attacks of their own. Although the United States tried to negotiate peace between the Osages and the Western Cherokees, the Western Cherokees Desiree revenge. U.S. officials feared that after the attacks against Clermont's village, the Osages would respond with more violence, impeding eastern Indian migrations. It was viewed as necessary after only 6,000 members of the Five Tribes voluntarily moved west. Proponents believed that Five Tribe members would have a better opportunity of becoming «civilized» if they were separated from Anglo society.
