Answer:
The structure your are referring to is showing the virus's genome.
Step-by-step explanation:
Viruses can be described as a tiny agent which multiplies inside a host cell and is usually harmful for the host cell.
The genome of a virus might be in the form of DNA or RNA. In the figure you might be referring to, there are two strands of genome present so we can say that the virus has DNA as genome. All life of life forms, from bacteria to animals and plants can be infected by viruses.
