The complete, mature and infection virus particle is known as:
Correct answer: C. Virion
- A. Venome
- B. Genome
- C. Virion
- D. Capsid
Explanation
a. Venome:"Venome" is not a recognized term in the context of virology or viruses. It does not refer to any specific component or structure of a virus. b. Genome: The genome of a virus refers to its genetic material, either DNA or RNA. It carries the instructions for the virus to replicate and produce new virus particles. While the genome is a crucial part of a virus, it does not represent the complete, mature, and infectious virus particle. c. Virion: The term "virion" refers to the complete, mature, and infectious virus particle. It includes the genetic material (genome), as well as the protein coat (capsid) that surrounds and protects the genetic material. The virion is the fully formed, functional virus particle that is capable of infecting host cells. d. Capsid: The capsid is the protein coat that surrounds the genetic material of a virus. While important for protecting the genome, the capsid alone does not constitute the entire infectious virus particle. Correct Answer: c. Virion Explanation: A virion is the complete, mature, and infectious virus particle, consisting of the genetic material (genome) and the protein coat (capsid). The term "virion" is used to describe the fully assembled and functional form of a virus that can infect host cells. Summary: The correct answer is c. Virion. The virion represents the entire infectious virus particle, encompassing both the genetic material (genome) and the protective protein coat (capsid). This distinction sets it apart from options like genome and capsid, which individually do not represent the complete infectious unit. The term "venome" is not recognized in this context.

About Viruses
Viruses are acellular infectious particles made of genetic material enclosed by a protein capsid, sometimes with a lipid envelope. Their replication depends on a host cell and may follow lytic or lysogenic cycles, so viral structure and reproduction differ fundamentally from those of cellular organisms such as bacteria.
