Answer:

The correct answer is a gene

Explanation:

The DNA segment that carries information for coding one protein or polypeptide is called a gene. According to one gene-one polypeptide hypothesis, each gene is responsible for making a single chain of the polypeptide.

Originally it was said that one gene codes for one enzyme but later it was found that some gene also codes for non-enzyme proteins and single polypeptide chains. So after this research, the theory was modified and one gene-one polypeptide theory came. Therefore the right answer is gene.

Mangrove forests were traditionally viewed as unhealthy, unproductive environments. Please select the best answer from the choic
dedylja [7]

Mangrove forests or swamps grow in saline and humid region of the tropical and subtropical areas. They were considered unhealthy, unproductive environments.

<h3>What are mangroves?</h3>

Mangroves are special forest trees that are found in regions of high salinity. In earlier times they were considered unhealthy and unproductive for the environment.

They were seen as of no importance and the people wanted them to remove the trees so the environment can become healthy again.

Its ecological value was not known at that time and was considered a waste and mess. But now people have to account for their importance of them as they help to improve the water quality and aid as the breeding place for the fishes.

Therefore, the statement is true.

Apply lesson concepts to explain why many prokaryotes are adapted for living at the normal internal temperature of the human bod
ankoles [38]

Many prokaryotes are adapted to live inside the body because the majority of bacteria are mesophilic.

Depending on the optimal temperature of development, there are three types of bacteria:

* Mesophilic bacteria prefer average temperatures between 20 and 40 ° C. The majority of bacteria is mesophilic. This is the case of pathogenic bacteria of man and animals, but also commensal bacteria of natural cavities, cutaneo-mucous membranes and especially saprophytic environmental bacteria involved in the degradation and recycling of dead organic matter. (necromass).

* The psychrophilic bacteria have an optimal temperature of development close to 0 ° C.

* Thermophilic bacteria can live at high temperatures (45 ° C in hot springs).

Complete the following vocabulary exercise related to the process of translation of mRNA to protein by the ribosome. Match the w
schepotkina [342]

The answers;

1. Termination. Out of the 64 codons, UAG, UAA, and UGA are the stop codons that terminate translation when encountered by the ribosome. These three do not code for any amino acid but rather cause the translation complex to dislocate.


2. Translation. In this process, the ribosome ‘reads’ the codon and brings in a t-RNA with an anticodon to the codon. This tRNA carries a specific amino acid (for that codon) and engages in the P-site of the ribosome. The amino acid is taken from the t-RNA and used to elongate the polypeptide chain being formed. Thereafter the empty t-RNA dislocates.


3. Aminoacyl-tRNA synthetase. When a tRNA brings in an amino acid to the initiation complex, it is dislocated when ‘empty’. Aminoacyl-tRNA synthetase then catalyzes the reattachment of another amino acid through a chemical reaction called esterification. The cognate tRNA then become an aminoacyl-tRNA.


4. tRNA . Every tRNA has an amino acid attached to it. The type of amino acid (out of the 22 amino acids) is determined by the anticodon on the tRNA. There are many codons that are amino acids meaning that there are redundant codons that specify for the same amino acid.


5. Initiation. Initiation begins by the formation of an initiation complex. This complex is comprosed by the two subunits of the ribosome, and the mRNA. The complex becomes compelete when a Met-tRNA (a tRNA with a methionine amino acid) engages the P-site and then translation begins.
