Answer:

It is an example of enzyme activation through the pH of the environment surrounding the enzyme.

This phenomenon is called proenzyme, proenzymes are inactive enzymes that, due to chemical changes in the environment that vary, are activated or not depending on these.

Explanation:

Proenzymes, generally the best known or named, are found in the digestive system, where the sequential digestion of food is essential, with an order, and the enzymes must be controlled or activated at certain moments of digestion.

Proenzymes can be activated by the presence of chemicals, pH acids and even pH alkalinity, the change of the medium is what gives the enzyme permission to start with its reaction effect.

Usually this happens with enzymes that must be controlled, and that their activity must be in certain periods so as not to generate pathologies or even destroy a tissue of the organism.

Methionine-methionine leucinelysine that a mutation in the DNA occurs so that the fourth base (counting from the 5' end) of the messenger RNA.

mRNA codons are read from 5' to 3' , and they specify the order of amino acids in a protein from N-terminus (methionine) to C-terminus. The mRNA sequence is: 5'-AUGAUCUCGUAA-5'

Ciodons which is broke the sequence into a series of three-nucleotide units. There are three-letter nature of codons that the four nucleotide found in mRNA such as A, U, G, and C all these can produce a total of 64 different combinations. The sequence of the tRNA anti-codon is 3'-UGC-5' and the tRNA will carry the amino acid which is the encoded by the codon.

Explanation:

A community is defined as a group of populations of two or more different species which inhabit the same area at a certain time.

Community ecology is the study of the interactions between species in communities through time on a certain place. It includes the study of the distribution, structure, demography, and interactions between populations.
