Answer:

The culturing system depends on the sort of microbe allotted to segregate namingly bacteria, viruses, or fungi. Each microbial pathogen has particular culture media for disconnection and for development or replication, we need culture media.for model bacterial pathogen can be separated by plating the example in fitting media by 3 strategies that are streak plate or pour plate or spread plate  

Out of the above streak, plate gives the best outcomes in single disengaged provinces which can be additionally cultured and characterized for creation of pure culture

Sequence of amino acids in a polypeptide chain of protein molecule coresponds to the sequence of nucleotides on mRNA for that pr
tamaranim1 [39]

Answer:

330

Explanation:

A codon is the sequence of three nucleotides on mRNA that refers for particular amino acid during translation (protein synthesis) process. The four nucleotides arrange themselves in various combinations to produce different codons. The tRNA with corresponding anticodon attach the particular amino acid to polypeptide chain during translation.

Remember there is always a stop (UAA) and start codon (AUG) for the synthesis of polypeptide and stop codon does not contribute for any amino acid. It just terminate the polypeptide chain synthesis. We know that a codon is made up of three nucleotide so our calculation will be.

                                     993-stop codon =990

                                     990/3=330

So that's why 330 amino acid will be incorporated in the polypeptide chain.
