For this assignment, you will write an essay describing the production of protein molecules through transcription and translation. your essay should include discussions of the following: dna mrna rna polymerase base pairing transcription translation trna rrna ribosomes amino acids protein protein synthesis is the synthesis of polypeptide chains which then produce the specific proteins based on the genetic code in dna. it occurs in two stages, transcription and translation. transciption occurs in the nucleus. dna contains the cistrons/genes which code for specific polypeptides. the part of the strand that forms the cistron is called the transcribing strand. it acts as a template and is transcribed to mrna. the complementary strand which does not carry the cistron is called the non-transcribing strand. an enzyme rna polymerase attaches itself to the promoter site next to the cistron on the dna and initiates transcription. the enzymes moves along the particular dna section in the 3' to 5' direction. nucleotides from nucleoplasm with bases complementary to the beses on dna are added one at a time to elongate the strand. base pairing occurs. for example, base adenine on dna pairs with uracil nucleotide and base cytosine will pairs with guanine nucleotide. translation is the process in which the codons in mrna are used to assemble amino acids in the correct sequence to produce a polypeptide chain. mrna binds to the binding site on the smaller ribosomal subunit. trna carries amino acid to the ribosome. cells posses more than 20 types of trna, more than enough for the different amino acids. the codon of mrna forms hydrogen bonds with the anticodon of trna. the trna detaches itself from mrna and returns to the cytoplasm to take up more amino acids. once aligned, peptide bonds are formed between adjacent amino acids, eventually forming a polypeptide chain. rrna consists of a single polynucleotide strand synthesised in the nucleus. the rrna form aggregates which proteins to form the large subunit and small subunit. the subunits leave the nucleus via nuclear pore into the cytoplasm. the subunits combine to form a ribosome. is this correct?

why many students visually perceive stem as a vapid class?

for many students, however, stem subjects are optically discerned as vapid, tedious, and destitute of authentic-world applications. science and math have always been a major part of the high school curriculum, but many students have disengaged from these subjects because they don’t optically discern that they have any pertinence to the authentic world or students’ daily lives. for them, math and science have become a set of rules, procedures, laws, theorems, and formulas to memorize. some students even develop math apprehensiveness and cerebrate they are incapable of learning higher-level mathematics.

why is stem paramount?

as the u.s. economy changes, the ordinant dictation for stem-capable workers is growing. in may of 2014, the u.s. bureau of labor statistics counted more than 8.3 million stem jobs, which accounted for 6.2 percent of total employment in the cumulated states. that number is expected to perpetuate to increment as u.s. companies grow and innovate to compete in the ecumenical economy. according to the u.s. department of labor, the average salary for all stem jobs is $85,570, which is virtually double the average salary for all jobs.

many people still envision stem professionals as wearing a white lab coat and conducting research in a laboratory. in authenticity, some of the most in-demand stem fields are petroleum engineering, process engineering, and computer engineering. these fields that are experiencing shortages of qualified candidates are additionally among the highest paying, with the average petroleum engineer earning an annual salary of $147,520 in may 2014 according to the u.s. bureau of labor statistics.

in additament, stem subjects edify students valuable skills that are vital for prosperity in all vocations, even those that do not directly require stem erudition. engagement in stem subjects avails students develop quandary-solving, critical mentally conceiving, and leadership skills. these skills are so ecumenical, in fact, that statistics relinquished in the summer of 2013 by the u.s. census bureau designated that about three-quarters of the people with a bachelor’s degree in stem fields are not working in those vocations. many non-stem employers are poaching stem-qualified job candidates because they are more ingenious and collaborative than their non-stem counterparts.

as the ecumenical economy perpetuates to evolve, the desideratum for stem-capable workers will perpetuate to grow. by getting edifiers and students involved in the stem kineticism, an incipient generation of adroit workers will be poised to energize and expand this exhilarating field.
