Question

Which of the following shows single stranded RNA and lack protein coat ?
a . Bacteriophage
b . Plant virus
c . Viroid
d . Animal virus​

Answer 1

Answer:

Viroid are the pathagones that shows single stranded RNA and lacks protein coat.

Explanation:

VIROIDS are Plant Pathagones these do not have external covering called as CAPSID or PROTEIN COAT.

Answer 2

Viroid shows single stranded RNA and lack protein coat

Explanation:

• Option (C) is Viroid is correct answer.
• Viroids are tiny organisms that cause illness.
• They are made up entirely of a single-stranded circular RNA strand.
• They do not have a protein covering, unlike viruses.
• All known viroids are found in angiosperms, and the majority of them cause illnesses with varying financial ramifications for humans.
• Option (A) Bacteriophage is incorrect answer.
• A bacteriophage is a virus that causes bacteria to get infected.
• Because bacteriophages kill their host tissue, the term "bacteriophage" literally means "bacteria eater.
• Bacteriophages are all made up of a nucleic acid molecule encased in a protein framework.
• Option (B) Plant virus is incorrect answer.
• Studies on plant viruses indicated that PD allows viral genome proteins, known as motility proteins, to travel from cell to cell (MPs).
• To generate nucleoprotein complexes, viral MPs bind RNA/DNA in a sequence nonspecific way (NPC).
• Option (D) Animal virus is incorrect answer.
• A tiny infectious agent that cannot reproduce outside of a live animal system is known as an animal virus.
• Only one kind of nucleic acid, DNA or RNA, is found in animal viruses.
