Q. Adenovirus is a useful model of studying gene expression because __________

View solution

Q. Mouse β – globin gene has __________ introns.

View solution

Q. The amount of exon in the eukaryotic genome is higher than that of the introns.

View solution

Q. The mRNA of which eukaryotic protein lacks introns?

View solution

Q. Introns are nothing more than genetic load in the eukaryotic genome.

View solution

Q. Presence of introns facilitates the formation of several different mRNAs, thus increasing protein yield of different types but from same gene.

View solution

View solution

Q. In bacterial cell the 3 rRNAs 23S, 16S and 5S are derived from different transcripts.

View solution

Q. Which one of the following rRNA undergoes least post-transcriptional processing?

View solution

Q. The bacterial pre – rRNA undergo __________ cleavage.

View solution

Q. Which of the following types of processing is not used to prepare mature rRNA?

View solution

Q. Each tRNA is produced from different transcripts.

View solution

Q. The pre – tRNA involves cleavage by __________

View solution

Q. RNase P is a ribozyme.

View solution

Q. The common sequence for all tRNAs at their 3’ end is __________

View solution

Q. The 3’ CCA terminus is exceptionally added by the RNA polymerase during transcription.

View solution

Q. Though unusual, pre – tRNA also undergo splicing. It is achieved by the help of __________

View solution

Q. The transcription starts with a purine that ends with a __________

View solution

Q. The enzyme used for capping mRNA is a __________
