Vedclass · Answer

(D) $HIV$ is a spherical virus with a diameter of about $90-120 \ nm$.Its genome consists of two identical molecules of single-stranded $RNA$ and is associated with reverse transcriptase enzymes.The envelope consists of a lipid bilayer derived from the host cell membrane with projecting glycoprotein spikes.$HIV$ is a retrovirus that specifically attacks helper $T$ cells ($CD4^+$ cells).By destroying these cells,it cripples the acquired immune response,as the immune system cannot signal $B$ cells to produce antibodies effectively.This leads to a state of immune deficiency known as $AIDS$ (Acquired Immuno Deficiency Syndrome).
