To solve this problem, we need to match the items in List I with the appropriate descriptions in List II. Let's analyze each item:$\newline \bullet$A. RNA polymerase III:$\newline$ - RNA polymerase III is responsible for transcribing small RNAs, including tRNA and some snRNAs.$\newline$ - This matches with IV. SnRNAs, tRNA.$\newline \bullet$B. Termination of transcription:$\newline$ - The termination of transcription in prokaryotes often involves the Rho factor, a protein that helps in terminating transcription.$\newline$ - This matches with III. Rho factor.$\newline \bullet$C. Splicing of Exons:$\newline$ - Splicing of exons is a process that involves snRNPs (small nuclear ribonucleoproteins), which are part of the spliceosome complex.$\newline$ - This matches with I. snRNPs.$\newline \bullet$D. TATA box:$\newline$ - The TATA box is a DNA sequence that indicates where a genetic sequence can be read and decoded. It is a type of promoter sequence.$\newline$ - This matches with II. Promoter.$\newline$Now, let's match the items from List I with List II:$\newline A \rightarrow IV, B \rightarrow III, C \rightarrow I, D \rightarrow II \newline$This corresponds to Option 2.
