Translation is a vital process in biology that occurs in the cell, specifically in the ribosomes. It is responsible for the synthesis of proteins based on the information encoded in the messenger RNA (mRNA) molecule. The process involves converting the mRNA sequence into a specific sequence of amino acids, which are the building blocks of proteins.

The raw materials for translation include the mRNA molecule, which carries the genetic code from the DNA, and transfer RNA (tRNA) molecules. tRNA molecules have an anticodon region that pairs with the complementary codons on the mRNA, as well as an attached amino acid specific to that codon.

The process of translation begins when the mRNA molecule binds to a ribosome. The ribosome moves along the mRNA, reading the codons sequentially. Each codon is recognized by a specific tRNA molecule with a matching anticodon. The ribosome facilitates the binding of the correct tRNA molecule to each codon, bringing in the corresponding amino acid.

As the ribosome moves along the mRNA, it forms peptide bonds between the amino acids, creating a growing polypeptide chain. This chain continues to elongate until a stop codon is encountered on the mRNA, signaling the end of translation. At this point, the newly synthesized protein is released from the ribosome.

In summary, translation occurs in the ribosomes and involves the conversion of mRNA into a sequence of amino acids. The raw materials are mRNA and tRNA molecules, and the products are newly synthesized proteins.

Answer:

The microorganisms present metabolic wastes that serve as the primary source of food for other living things.

Bacteria that live free in the soil or in symbiosis with plants are essential to fix nitrogen, both nitrates and ammonia. These bacteria take nitrogen directly from the air, originating compounds that can be incorporated into the composition of the soil or living beings.

This property is restricted only to prokaryotes and is widely distributed among different groups of bacteria and some archaeobacteria. It is a process that consumes a lot of energy that occurs with the mediation of the enzyme nitrogenase, which the rest of the living organisms that cannot do or comply with this process is because they lack said enzyme.

Dunaliella is a genus of microscopic algae of the Chlorophyceae class and of the order Volvocales. All are unicellular, although with very varied morphologies.

Morphologically, its main characteristic is that they lack a rigid polysaccharide cell wall.

The ecology of this genus of green algae is characterized by its high tolerance to salinity, with eukaryotic organisms having greater tolerance to salt. They are euryhaline, adapted to salt concentrations from 50 mM NaCl to almost 5.5 M NaCl.

Explanation:

By nitrogen fixation is meant the combination of molecular nitrogen or dinitrogen with oxygen or hydrogen to give oxides or ammonia that can be incorporated into the biosphere. Molecular nitrogen, which is the majority component of the atmosphere, is inert and not directly usable by most living things. Nitrogen fixation can occur abiotic (without the intervention of living beings) or by the action of microorganisms (biological nitrogen fixation). Fixation in general involves the incorporation into the biosphere of a significant amount of nitrogen, which globally can reach about 250 million tons per year, of which 150 correspond to biological fixation.

The region in the mRNA that begins with the start codon and specifies the entire amino acid sequence of a polypeptide is called the coding sequence or the open reading frame (ORF).

A specific protein's genetic code is found in the region of the mRNA molecule known as the coding sequence. The amino acid methionine is coded for at the start codon AUG, and one of the three stop codons (UAA, UAG, or UGA) marks the conclusion of the protein-coding sequence.

The ribosome reads the mRNA molecule in units of three nucleotides, known as codons, and associates each codon with the corresponding amino acid during translation. This process continues until a stop codon is reached, at which point the newly made protein is released from the ribosome. The amino acid sequence of the protein that an mRNA molecule codes for depends heavily on the open reading frame of that molecule.

Explanation:

A protein that binds to the operator and blocks the rna polymerase is called repressor

The operator gene is bound by a repressor protein that prevents the operon's structural genes from being transcribed in the absence of an inducer.

RNA polymerase interacts with a region of DNA called the promoter, which is near to the gene's start. In bacteria, each gene has its own promoter, which is a collection of co-transcribed genes. The template for transcription is produced when RNA polymerase splits the DNA strands into single strands after binding.

Repressors prevent RNA polymerase from connecting to or moving forward by attaching to operator sequences that are downstream of the promoters and limiting transcription.

The given problem can be solved using the weight and isoelectric point of the proteins A,B, and C. Under the influence of an electric field, the heavy molecules (proteins) travel a shorter distance than the light molecules. Protein molecules have a zero-net charge at the isoelectric point.

Protein molecules are separated using SDS PAGE (sodium dodecyl sulphate polyacrylamide gel electrophoresis). Under the influence of the electric field, the molecules separate.

Isoelectric focusing is a technique used in the separation of molecules based on their charge.

The isoelectric point of a molecule is the point at which it has a zero-net charge (the power of hydrogen).

Step: 1

The size of the protein particles can be calculated based on the distance travelled by the protein in the problem's figure.

Protein C is the smallest, followed by protein B and then protein A.

In the SDS PAGE, protein C has travelled the most distance, followed by protein A and protein B.

The movement of a protein molecule under the influence of an electric field is inversely proportional to its size.

The molecule with the smallest size (and thus the lowest molecular weight) spends the most time in the size exclusion column.

Protein B is larger in size, resulting in a higher molecular weight. It will require the least amount of elution volume, followed by proteins A and C.

Protein B, which is larger and has a higher molecular weight, will not pass through every pore in size exclusion chromatography and will thus elute quickly. Protein B would come after protein A and protein C. Furthermore, the protein that elutes first requires the least amount of elution volume.

Protein C will require the least elution volume if the proteins are placed in increasing volume in the chromatographic column separating proteins based on cation exchange.

Protein C will come after protein B and protein A.

The proteins are supposed to be run at pH 5. At this pH, the protein with a high isoelectric point will acquire more negative charges and be attracted to the cation much faster. It will also necessitate a small elution volume. Protein A, with an isoelectric point of 8.2, will have the most negative charges, followed by protein B and protein C. As a result, protein c will require the least amount of elution volume, followed by protein B and protein A.
