PSTV have : -a)Single stranded RNA not enclosed by protein coatb)D.S. ...
Overview:
PSTV stands for Potato spindle tuber viroid, which is a type of viroid. Viroids are small infectious particles that are composed of a single-stranded RNA molecule. They are similar to viruses but do not have a protein coat. Instead, the RNA molecule of a viroid is able to replicate and cause disease in plants.
Explanation:
Viroids:
- Viroids are small, non-coding RNA molecules that are capable of causing diseases in plants.
- They are composed of a single-stranded RNA molecule that does not encode any proteins.
- Viroids are able to replicate and cause disease by utilizing the host plant's cellular machinery.
Potato Spindle Tuber Viroid (PSTV):
- PSTV is a specific type of viroid that infects potato plants and causes diseases such as potato spindle tuber disease.
- The RNA molecule of PSTV is single-stranded, meaning it consists of a single chain of nucleotides.
- Unlike viruses, viroids do not have a protein coat or outer envelope.
- This lack of a protein coat allows the RNA molecule of the viroid to directly interact with the host plant's cells and initiate infection.
Options:
a) Single stranded RNA not enclosed by protein coat: This is the correct answer. PSTV is a viroid with a single-stranded RNA molecule that is not enclosed by a protein coat.
b) D.S. DNA enclosed by protein coat: This option is incorrect. Viroids do not contain DNA, and they do not have a protein coat.
c) Double stranded RNA enclosed by protein coat: This option is incorrect. Viroids are composed of single-stranded RNA and do not have a protein coat.
d) S.S. DNA not enclosed by protein coat: This option is incorrect. Viroids are composed of RNA, not DNA.
Conclusion:
In conclusion, PSTV is a viroid that contains a single-stranded RNA molecule. It does not have a protein coat or envelope. The correct option is a) Single stranded RNA not enclosed by protein coat.
