Answer:
The correct answer is "It blocks translocation of the large ribosomal subunit, preventing the movement of peptidyl-tRNA from the A (acceptor) site to the P (peptidyl) site of the ribosome".
Explanation:
Many antibiotics work by inhibiting bacterial protein synthesis, and they act at different levels of the synthesis process. The mechanism of action of antibiotics could be assessed using different strategies on the laboratory. In this case an antibiotic with the synthetic polynucleotide 5’-AUGUUUUUUUUU resulting in disrupting peptide synthesis to Met-Phe would block translocation of the large ribosomal subunit, preventing the movement of peptidyl-tRNA from the A (acceptor) site to the P (peptidyl) site of the ribosome. The A site is the point of entry of the tRNA and where the first and second amino acid are added, whereas the P site is where the whole polypeptide is synthesized. This antiobiotic does not allow that protein synthesis continues to the P site of the ribosome, therefore the proteins synthesized only have two amino acids.
Explanation:
Genetic diversity is important because it could ensure that certain groups of individuals , species , or populations will be able to adapt to certain environmental factors. besides having to deal with environmental conditions , genetic diversity renders them THE ABILITY TO RESIST EMERGING DISEASES AND EPIDMICS.
Answer: C) The event at the end of the Triassic Resulted in the extinction of fewer fauna’s then in any other period
Explanation:
Looking at the graph, the event at the end of the Triassic resulted in the smallest dip in the amount of fauna in the graph. This means that this event resulted in the extinction of fewer faunas than any of the other five major events.
Option A is wrong as the event at the end of the Devonian decreased the number of Cambrian fauna.
Option B is wrong as the event at the end of the Cretaceous resulted in a decrease in the Paleozoic fauna.
Option D is wrong because the event that resulted in the Extinction of more fauna’s then in any other period was the event at the end of the Permian.
