Which of the following property is not present in RNA?

Options

A. D-ribose Sugar
B. essential genetic material for plant virus
C. single polynucleotide chain
D. replicate itself

Explanation

To determine which property is not present in RNA, let's analyze the given options step by step.

### Step 1: Identify the components of RNA
RNA (ribonucleic acid) is made up of three main components:
1. A sugar (specifically D-ribose)
2. A phosphate group
3. A nitrogenous base (adenine, guanine, cytosine, or uracil)

### Step 2: Evaluate the options
1. **D-ribose sugar**: This is indeed present in RNA as it is one of the components of the nucleotide structure.

2. **Essential genetic material for plant viruses**: RNA serves as the genetic material for many viruses, including plant viruses. This statement is true.

3. **Polynucleotide chain**: RNA is a polynucleotide, which means it is made up of a chain of nucleotides linked together. This is also true.

4. **Replicate itself**: This is the key option to evaluate. RNA does not have the ability to replicate itself in the same way DNA does. While RNA can be transcribed from DNA and can serve as a template for protein synthesis, it does not possess the inherent ability to replicate independently.

### Conclusion
The property that is not present in RNA is the ability to replicate itself.

### Final Answer
**Replicate itself**
