Answer:
(D) The protein that is first made gets modified afterwards
Explanation:
The first amino acid in any protein in eukaryotes is always methionine (Met). But, in some proteins any amino acid other than methionine may be found at N terminus of a protein. Like in this example, the HBB protein starts with a valine (Val) instead of methionine. It happened because of post-translational modification which includes the action of aminopeptidases which cleave 1 or 2 amino acids from N terminus of a protein as a result of which any amino acid other than methionine may exist at amino terminus.
Answer:
C. These antibiotics interfere with protein synthesis within eukaryotic mitochondria.
Explanation:
Eukaryotic mitochondria have 70s ribosomes and is made up of 50s and 30s subunits which has similarities to the ribosomes of bacterial cells. This likeness
at times causes antibiotics that ought to be toxic to bacterial ribosomes to cause some toxicity in eukaryotic cells instead.
Answer:
El umbral de audición es la intensidad mínima de sonido capaz de impresionar el oído humano. Aunque no siempre este umbral sea el mismo para todas las frecuencias que es capaz de percibir el oído humano, es el nivel mínimo de un sonido para que logre ser percibido.
