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.
Explanation:
The correct answer for this question is "A. withdraw American forces from Berlin." The Berlin Crisis of the late 1940s was an effort to <span>withdraw American forces from Berlin. This crisis has to be taken into action then and there to avoid future difficulties and problems within the nation.</span>
Answer:Making Economic Decisions
Individuals are forced to make trade-offs every time they use their resources in one way and not in another. The cost of making a trade-off is known as opportunity cost—the value of the next best alternative that has to be given up to do the action that is chosen.
Explanation:
Narrowing down choices until one arrives at only two options is an example of "<em><u>ideological polarization</u></em>
<em><u>ideological polarizationbipartisanship."</u></em>
<em><u>Ideological polarization bipartisanship</u></em> is a type of ideology in which individuals have various divergent beliefs on ideological issues.
However, to pick the right or favorable options, one narrowed these several divergent beliefs to two options and their find compromise.
The electorates usually use the ideological polarization bipartisanship to choose the candidates to vote for.
Hence, in this case, it is concluded that the correct answer is option C. "<em><u>ideological polarization bipartisanship."</u></em>
