Many antibiotics inhibit prokaryotic translatin without disrupting protein synthesis of the host cell. These antibiotics work via all of the following mechanisms EXCEPT

An antibiotic, which inhibits translation in eukaryotes is

Which one of the following statement is incorrect regarding the protein synthesis?

Hyperconjugation describes the orbital interactions between the p-systems and the adjacent s-bond of the substituent group(s) in organic compounds. Hyperconjugation is also called as Baker and Nathen effect. The necessary and sufficient condition for the hyperconjugation are : i) Compound should have at least on sp2 hybrid carbon of either alkene, carbocation or alkyl free radical. ii) A-carbon with respect to sp2 hybrid carbon should have at least one hydrogen. Hyperconjugation are of three types: (i) s(C-H), p-conjugation. (iii) s(C-H), positive charge conjugation iv) s(C-H), odd electron conjugation The hyperconjugation may be represented as Number of resonating structures due to hyperconjugation = (n + 1) where n is the number of a-hydrogen. Greater is the number of such forms, more is the stability of the species under considersation. Which of the following carbocations will show highest number of Hyperconjugation forms?
