Statement 1: Ribozymes are RNA molecules which catalyse the synthesis of certain specific RNAs and removal of introns from mRNA.
Statement 2: Ribozymes are proteinaceous enzymes.
Explanation:
What are Ribozymes?
Ribozymes are RNA molecules that possess catalytic activity. They were discovered in the 1980s and were initially thought to be solely catalytic RNA molecules. However, it was later discovered that some ribozymes can also catalyze the synthesis of certain specific RNAs and removal of introns from mRNA.
Statement 1: Ribozymes are RNA molecules which catalyse the synthesis of certain specific RNAs and removal of introns from mRNA.
This statement is correct. Ribozymes are RNA molecules that can act as catalysts, meaning they can speed up specific chemical reactions. They can catalyze the synthesis of certain specific RNAs, which means they can help in the formation of new RNA molecules. Additionally, they can also catalyze the removal of introns from mRNA molecules. Intron removal is an important step in the process of gene expression, where non-coding regions of mRNA are removed to generate a mature mRNA molecule that can be translated into protein.
Statement 2: Ribozymes are proteinaceous enzymes.
This statement is incorrect. Ribozymes are not proteinaceous enzymes. Enzymes are typically proteins that act as catalysts in biological reactions. However, ribozymes are unique because they are RNA molecules with catalytic activity. They can carry out enzymatic functions without the need for additional protein components.
Conclusion:
In conclusion, option B is the correct answer. Statement 1 is correct as ribozymes are RNA molecules that can catalyze the synthesis of specific RNAs and removal of introns from mRNA. Statement 2 is incorrect as ribozymes are not proteinaceous enzymes, but rather RNA molecules with catalytic activity.
Statement 2: Ribozymes are proteinaceous enzymes.
