A) Direct penetration
B) Injecting nucleic acid
C) Endocytosis
D) Endocytosis through chemical stimulators
Correct Answer: B
Solution :
Viruses are acellular or non-cellular particles that contain an inner core of genetic material DNA or RNA that is covered by a non- genetic protein 'coat' called a capsid, The protein coat is made up of protein subunits called capsomeres. Together, the capsid and the nucleic acid core form the nucleocapsid. The nucleocapsid may be either enveloped or naked. Plant viruses are generally naked but animal viruses may or may not possess envelop. Plant viruses generally enters into the host through wounds as they cannot penetrate the cuticle of the host cell, so the entire virus come in contact with host cell. The enveloped viruses inject their own nucleic acid inside the host cell.You need to login to perform this action.
