Explanation / Answer
1. SnRNA are part of splicing machinery which plays an important role in post-transcriptional modification of RNA i.e removal of introns from pre-mRNA so the ans will be (a).
2. Ans C
Epistasis is the interaction of diffetent genes for a particular phenotype.Here,effect of one gene is dependent on the presence of another gene.
3.ans C
Aminoacyl-tRNAs play role in translation process where mRNA are translated into proteins with the help of ribosomes and tRNA.
4.Ans D
Prokaryotes never undergo post transcriptional modifications as they do not have introns in their mRNA.
5.ans D
Enhancers are the specific DNA sequences which are found away from promoter region but increases rate of transcription by interacting with transcription factors and RNA polymerase
6.Small populations result in fixing of allele frequency rather than change in allele frequency.
7.a.
Rest all are going to result in genetic drift.
