Which of the following is an example of post translational modification ?: (A) Gamma carboxylation of glutamate residues, (B) N glycosylation of proteins, (C) 7 methyl Guanosine capping, (D) Poly A tail addition
Answer is B. Ans. is 'a > b' i..e, Gamma carboxylation of glutamate residues, N glycosylation of proteins Impoant post-transcriptional modifications are?7 methyl guanosine capping along 5' end of mRNAPoly A tail addition along 3' end of mRNARemoval of introns and linkage of exons - RNA splicing
