Read the lgiven statements and select the correct option .
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.

Options

A. Both statements 1 and 2 are correct.
B. Statement 1 is correct but statement 2 is incorrect.
C. Statement 1 is incorrect but statement 2 is correct.
D. Both statements 1 and 2 are incorrect.

Explanation

To solve the question, we need to evaluate the two statements provided:

**Step 1: Analyze Statement 1**
- Statement 1 claims that ribozymes are RNA molecules that catalyze the synthesis of certain specific RNAs and the removal of introns from mRNA.
- This statement is **true**. Ribozymes are indeed RNA molecules that can act as enzymes, and one of their functions is to catalyze the splicing of RNA, which includes the removal of introns from pre-mRNA.

**Step 2: Analyze Statement 2**
- Statement 2 claims that ribozymes are proteinaceous enzymes.
- This statement is **false**. Ribozymes are not proteins; they are RNA molecules. While most enzymes are proteins, ribozymes are a unique class of enzymes that are made of RNA.

**Step 3: Conclusion**
- Based on the analysis, Statement 1 is correct, and Statement 2 is incorrect. Therefore, the correct option is that Statement 1 is true, and Statement 2 is false.

**Final Answer:**
- Statement 1 is correct; Statement 2 is incorrect.
