Answer:
The best possible outcome for the cell in the event of mis-copied mRNA is for the mis-copied sequence to code for the same amino acid as the correct sequence would have done
Explanation: The process of transcription during which the message in DNA is transcribed as genetic codes into mRNA is sometimes not error proof. Synthesized mRNA is usually transported into the cytoplasm where the codes are translated into protein.
Each genetic code which is usually a sequence of 3 purine/pyrimidine bases codes for an amino acid. However, due to the degenerate nature of the genetic codes, more than one codon can code for the same amino acid. The degenerate nature is caused by the fact that there are 64 possible codons and there are 20 amino acids in nature. For example, UUA, UUU and UUG can be coding for the same amino acid in nature.
Hence, if a mistake occur during transcription, the best possible scenario for the cell is that the mis-copied sequence will end up coding for the same amino acid(s) as the correct correct sequence would.
Answer:
The correct option is B. Jean Charcot was the French neuroscientist that helped legitimatize the practice of hypnosis.
Explanation:
Hypnosis can be described as a state in which a person is numb or kind of asleep but is strongly focused to respond to questions being asked by the psychologist. This technique is used by psychologists for the treatment of psychological disorders. Hypnosis has also been known to serve as a therapy for pain management.
Jean Charcot was a French scientist that made up his name by identifying a number of neurological disorders. He is also known to legitimatize the practice of hypnosis for psychological purposes.
Answer:All energy sources have some impact on our environment. Fossil fuels—coal, oil, and natural gas—do substantially more harm than renewable energy sources by most measures, including air and water pollution, damage to public health, wildlife and habitat loss, water use, land use, and global warming emissions.
Explanation:It becomes clear that for more than 45 percent of respondents, solar energy was the most environmentally friendly energy source. The energy generated by the wind was also a considered to be pro-environment by almost 24 percent of the respondents.
The right option is; B. Facultative halophiles
Facultative halophiles are the group of microorganisms that is most likely to spoil a freshwater trout preserved with salt because they can survive, grow and reproduce in extremely salty environments. Facultative halophiles can also survive and reproduce at not-high salt concentrations as they do not rely on high salt concentrations for growth. Examples of facultative halophiles are Staphylococcus aureus and Streptococcus spp.
