igomit [66]

They are both at the final stage of development and this is the characteristic that is shared by both inceptisols and entisols, the soils of flood plains. The correct option among all the options that are given in the question is the third option or option "c". These kind of soils are found in variety of places like the tundra environments and glacial deposits.

From a chemical view, how is an amino acid is being recognized by its specific aminoacyl tRNA synthetase?

hammer [34]

During translation, rRNA and tRNA read mRNA in 5´ to 3´ direction. According to the codons being readen, tRNA transfers the correct amino acids to build the polypeptide chain. A codon is a short sequence of three nucleotides that store the genetic information for the aminoacids´ assembly.

Each tRNA has two important sites. One of them that couples with the codon of the mRNA molecule, named anticodon. The other site couples with an amino acid through the action of the aminoacyl-tRNA synthase enzyme. The whole complex, amino acid + enzyme + tRNA is named aminoacyl-tRNA.

Each tRNA is recognized by a specific aminoacyl-tRNA synthase enzyme. The enzyme is also capable of recognizing a specific amino acid. Let us say, for instance, that tRNA is specific for phenylalanine. The molecule is attached to the enzyme that is specific for that tRNA(Phe). Then, when the enzyme and tRNA(Phe) are together, they get to find phenylalanine. The enzyme links the aminoacid to the RNA. Once the whole complex is formed, the tRNA gets to pair its anticodon with the mRNA codon. This is,

Recognition of enzyme and the specific tRNA(aa) ⇒ aa being aminoacid
Recognition of enzyme and the specific aminoacid
Linkage of the aminoacid to RNA by the enzyme action
Pairing of tRNA anticodon to mRNA codon.

Considering that there are twenty amino acids available, there are also twenty complexes of aminoacyl-tRNA, one for each amino acid. Each of the mRNA codons represents one of the 20 amino acids used to build the protein. Each amino acid can be codified by more than one codon. Of the total 64 codons, 61 codify amino acids, and one is a start codon. The left three codons are stopping translation points.

tRNA decodes genetic information from the nucleotidic sequence in the mRNA molecule and allows amino acids to align composing the new protein.

Once the new peptidic link joins, placing together the new amino acid to the growing peptidic chain, the binding between the amino acid and the tRNA molecule breaks. The tRNA is now free to join another amino acid and repeat the cycle.

In conclusion, a specific aminoacyl-tRNA synthase enzyme recognizes a tRNA, which is also specific for a certain amino acid. When together, the enzyme recognizes the amino acid and links it to the RNA. The whole complex is known as aminoacyl-tRNA. Once the tRNA is joined to its amino acid, it gets to pair a codon of mRNA to add that amino acid to the new synthesizing protein.

How can carbohydrates, lipids, and proteins be detected in foods?

tino4ka555 [31]

The Benedict’s Test is the test which can detect carbohydrates and glucose in foods. During this process, the sample or the food is placed into a test tube and then some drops of Benedict's solution is added to it,and is then put into a beaker of boiling water. When the mixture of food and the Benedict substance turns reddish orange instead of staying blue, this means that it is positive. The mixture has simple sugar or has carbohydrates or glucose. On the other hand, lipids are tested using the brown paper test. When the paper turns transparent when a drop of food is put into it, it means that is is positive as well. When you want to test if the food has proteins, you have to test it with Biurets. Observe if the color change when you put some Biurets solution to the food sample. It is positive if the food turns light purple. Test if the food is positive with starches through the use of iodine. Food having iodine drops should turn purple instead of staying a yellow color.
