Label the steps 1-4 of translation that led to gene expression: ? . a peptide bond is created between the first two amino acids formed. ? . once a protein is formed, the gene for a particular trait is expressed. ? . a chain of amino acids is formed, creating a protein. ? . the first codon of mrna attaches to a the anticodon of trna to form a chain of amino acids.

The right matches are:

2nd. ==> A peptide bond...

4th. ==> Once a protein...

3rd. ==> A chain of amino acids...

1st. ==> The first codon of mRNA...

Gene expression is the mechanism that groups together all the processes that lead to a functional product of the gene.

Transcription is the process of obtaining a strand of RNA from a strand of DNA.

Once the messenger RNA is mature, it is exported outside the nucleus, in order to recruit the ribosomes and proceed with the translation.

The nucleotides are read in groups of 3, the codons. Each codon encodes an amino acid, or allows to initiate or stop the translation.

Once the ribosome has settled on the mRNA strand, it will go through it until it finds the first AUG codon to start the translation. The ribosome will then read each codon, which will result in the production of an amino acid. This produces the production of an amino acid chain, in other words a protein. The translation ends when the ribosome encounters a stop codon.

So, at the end of this process, we get a functional product of the gene: a protein.

The steps of the translation that lead to gene expression is the attachment of mRNA to tRNA, peptide bond formation, chain of amino acid forming proteins and the expression of the gene for a specific trait.

The biological process of protein formation with the help of amino acids and mRNA is called translation. The amino acids produced are linked by the peptide bonds to create proteins.

Gene expression is a process of the formation of active proteins required by the body for functional and structural roles. The process of transcription and translation forms the amino acid and the proteins needed for gene formation.

In the transcription process, the mRNA start codon binds to the anticodon present on the tRNA so that the chain of amino acids can be created.

The amino acids thus formed are joined together by peptide bonds and the chain of amino acids creates the proteins. The active protein formed codes for a particular trait in the form of genes that are specific and can be dominant or recessive.

Therefore, the products of the translation lead to gene expression.

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.
