Answer: Two characteristics define brightness: luminosity and magnitude. ... The size of the star and its surface temperature determine its luminosity. Apparent magnitude of a star is its perceived brightness, factoring in size and distance, while absolute magnitude is its true brightness irrespective of its distance from earth.
Explanation:
Answer:
The correct answer would be the loss of its function.
Being protein in nature, the function of insulin depends on the amino acid sequence of the polypeptide chains.
Change in the amino acid sequence may result in a change of shape or structure of the protein.
Consequently, it would not be able to interact with cell surface receptors.
Thus, it would lose its function.
First, scientists isolate the gene that controls insulin production. Then, they take that gene and insert into a plasmid (a circular ring of DNA found in bacteria). When the bacterium with that plasmid reproduces, it carries that insulin-producing gene. Then they can either mass-reproduce that bacteria or transfer the plasmid to another rapidly-reproducing bacteria. After some time, they harvest the insulin from the bacteria.
