Prokaryotic cells, being unicellular organisms, do not have a defined nucleus. They have a nucleoid in place of the nucleus which is formed of a single chromosome consisting of double stranded DNA.
Answer:
Translation may be defined as the process of formation of protein product from the RNA molecule. Three main steps of translation are initiation, elongation and termination.
Antibiotics can effect the different process of translation. Tetracycline can block the A site and thus prevent the binding of the transfer RNA with the ribosomes. This effects the initiation process of translation.Other antibiotics can directly affect the growth of the polypeptide chains and may prevent the elongation of the translation.
Answer;
