You are working in a molecular virology laboratory, studying a diseased tropical plant. You identify a circular ssRNA genome that is 350 nucleotides in length. No other viruses are infecting the plant. Which of the following statements in relation to these observations is CORRECT?
A) The genome demonstrates it can reproduce in the host, therefore it is a viroid.
B) The genome demonstrates it can reproduce in the host, therefore it is a virus.
C) The genome demonstrates it can reproduce in the host, therefore it is a satellite virus.
D) The genome demonstrates it can NOT reproduce in the host, therefore it is a viroid.
E) The genome demonstrates it can NOT reproduce in the host, therefore it is a virus.
