Answer: Missense mutation
Explanation:
Missense mutation is a type of point mutation where a single nucleotide is changed to cause substitution of a different amino acid. This in turns render the resulting protein non-functional.
In the case of sickle-cell disease, the sixth amino acid in the gene sequence, glutamate (GAG) is substituted with valine (GUA), due to Adenine nucleotide changed to Uracil nucleotide. Thus, missense mutation has occurred
Answer:
False
Explanation:
Oxidation process occurring in liver rids bloodstream of not 32% of alcohol present.
Once the alcohol enters the body, 5 percent of it is excreted in the form of the urine and another 5 percent is eliminated from the body by exhaling and the rest of the alcohol is converted to acetic acid by oxidation.
Thus,
Oxidation process occurring in liver rids bloodstream of 90% of alcohol present.
Answer: prokaryotes (single celled micro-organisms/microbes)
