Rna World

In order to match List I with List II correctly, we analyze each element:

Let's make the correct matches:

• RNA polymerase III: This enzyme is responsible for synthesizing tRNA and some small RNA molecules, including snRNA. Therefore, RNA polymerase III is paired with SnRNAs, tRNA (IV).
• Termination of transcription: In prokaryotes, Rho factor is involved in the termination of transcription. Thus, Rho factor (III) corresponds to termination of transcription.
• Splicing of Exons: The process where snRNPs (small nuclear ribonucleoproteins) are involved in splicing introns and joining together exons to form the final mRNA. So, splicing of exons corresponds with snRNPs (I).
• TATA box: This is a DNA sequence that indicates where a genetic sequence can be read and decoded, acting as a promoter. Thus, the TATA box corresponds to Promotor (II).

The correct matches are: A-IV, B-III, C-I, D-II.
