For the translation process, besides eIF2 and Met‐t‐RNA, the eukaryotic 80S ribosome also requires: UTP GTP ATP CTP 2. Which of the following statement is NOT correct regarding the genetic code? Third base of anticodon in not necessary for specificity The genetic code is not strictly universal One Amino acid can have more than one codon In eukaryotes the start codon is AUG3. The 35s and ‘mas’ promoters are used to express genes in _____ Mammalian cells Plant cells Fungal cells Bacterial cells4. Split genes are present in: All eukaryotes Most of the eukaryotes and some eubacteria Most of the eukaryotes and some archaebacteria All organisms5. The 20 different amino acids in the protein are normally coded by: 62 codons 60 codons 61 codons 63 codons6. When changes in the phenotype or gene expression occur without changes in the underlying DNA sequence, the phenomenon is called Mutation Eugenics Epistasis Epigenetics7. Which of the following antibiotic inhibit 80S ribosomes? Tetracycline Chloramphenicol Cyclohexamide Streptomycin8. A mutant phenotype due to a nonsense mutation can be rescued by a mutation in the tRNA gene. This rescue is an example of: Induced mutation Spontaneous mutation Suppressor mutation Deletion mutation9. A messenger RNA is 336 bases long including the initiation and termination codon. The number of amino acids in the polypeptide translated from this is: 111 110 333 60010. Which of the following non-coding RNAs is involved in RNA editing? snRNA gRNA siRNA miRNA11. UGA and UAA are nonsense codons. What kind of single point mutation would cause reversion of UAG to a meaningful codon? Transition Transversion Frameshift Inversion12. A protein which is to be degraded in the proteasome is tagged with: Ubiquitin Polyproline Formyl-methionine Polyglycine13. The anticodon sequence is located in: r‐RNA t‐RNA DNA r‐RNA14. If a sequence 5’AAA(AAA)n AAAAAC 3’ was transcribed in cell-free system and peptide obtained was partially hydrolyzed with carboxypeptidase, the result was an Aspargine residue and an oligopeptide. It suggests the direction of translation was: 5’-3’at pH 5.4 3’-5’ 5’-3’ 3’-5’ at pH 7.2 15.
