In industry, microorganisms are often cultured in an environment where ideal conditions are maintained through continual nutrient provision and waste renewal. Such a system is called a .

Continuous Culture  

Explanation:

In industry, a continuous culture is maintained by providing the nutrient on time and removing the waste materials on time so that the optimum conditions inside the medium is maintained.

It is done to minimize the efforts which is required when the preparation is done to prepare the nutrient and inoculate the bacterial species.

Then by the time the bacterial species starts growing and then the useful product is extracted. In order to save the time and efforts the nutrient is supplied and waste materials is removed along with the useful products.

explanation:

the sequence of amino acids in a protein determines its function. the dna sequence of a gene determines the amino acid sequence of the resulting protein. thus, any changes in dna sequence can result in changes in protein function. this is called a mutation.

dna is made up of six smaller molecules -- a five carbon sugar called deoxyribose, a phosphate molecule and four different nitrogenous bases (adenine, thymine, cytosine and guanine).
