Answer:
Enantiomers or optical isomers are chiral molecules which are non-superimposable mirror images of each other. ... Different enantiomers fit differently into the various enzymes that drive biochemistry. This explains why they often taste and smell differently and have different effects as drugs.
A common example of a pair of enantiomers is dextro lactic acid and laevo lactic acid
Answer:
(Bad idea)
Many people are against the idea of extending the DNA database because of the potential threat it has to our privacy. While a DNA profile provides very little information about someone, their DNA sample contains information that can reveal their ethnicity or how susceptible they are to disease.

"Is it ethical to have a national DNA database?" and it should be the first article that pops up
Answer:
18%
Explanation:
Chargaff's rule states that A = T and C = G
The equation for this must be A + C = T + G
A and T should both be .32 since they're equal
--> .32 + C = .32 + G
Both sides must equal each other by .50
.50 - .32 = .18
.18 × 100 = 18% Guanine and also 18% Cytosine
The correct answer is (d.) proteins. Higher organisms use nitrogen to make their protein. Food that is containing protein also involves nitrogen in it. Protein also has amino acids that contain nitrogen in it which is a necessary essential nutrient for the body.
