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.
Answer:
Canceled out
Explanation:
In a negative feedback loop, the product of the loop inhibits whatever initiated the loop, preventing more product from being formed.
This is in contrast to a positive feedback loop, where the product of the loop further stimulates whatever initiated the loop, resulting in even more product being formed.
hypothesis I assume for that
<span>No, they are not because the alleles at a gene on the pair of homologous chromosomes contributed by both parents may be different. One pair of homologous chromosomes comes from the father while the other pair comes from the mother. A pair of homologous chromosomes contains one maternal and one paternal chromosome that pair up with each other during meiosis. When a parent cell divides into two or more daughter cells; each daughter cells obtain one half of the duplicated set of chromosomes which may or may not. During meiosis the alleles at a gene may or may not be the same producing different phenotypes.</span>
