Answer:
The following are the steps for making the human insulin protein for the health care market:
1. Obtain the DNA from a human being who does not have diabetes.
2. Modify the human gene, and provide it a promoter, which will get turn on when placed within the E.coli cell.
3. Separate and make copies of the gene encrypting the insulin protein.
4. Application of electroporation or heat shock method in order to administer the human insulin gene within the living E.coli cell.
5. Development and growth of E.coli in the fermentation culture, and then extract and sell the humulin in the market.
B. homozygous for the recessive allele.
The only way you have a disease caused by a recessive allele is that both of your copies are recessive.
Concerning the balance of pollutants in the biosphere, Scientists have proved that the natural system of the earth is overwhelmed by pollution.
<span>Compare: both RNA and DNA have 3 nitrogenous bases: Adenine Cytosine and Guanine. Also b</span>oth have a phosphate groups in their nucleotides<span>
Contrast: </span>RNA is a polymer with a ribose AND a phosphate backbone. It has four different nitrogenous bases: adenine, guanine, cytosine, and uracil.
DNA<span> is a long polymer with deoxyriboses AND phosphate backbone. It also has four </span>different<span> nitrogenous bases: adenine, guanine, cytosine and thymine.
