Viruses are even simpler than bacteria cells. The basic of structure of all viruses is similar. Viruses have a core of nucleic acid surrounded by a protein coat. At their core, all viruses contain either DNA or RNA.Unlike animal and plant cells, viruses do not contain both nucleic acid. The Capsid is the DNA or RNA core of a virus that is surrounded by a protein coat.The capsid protects the nucleic acid. Besides a Capsid, some viruses, especially animal viruses, are covered with another protective coating called an Envelope.iruses are even simpler than bacteria cells.

What does Vietnam mean? Vietnam should be correctly written as Viet Nam. Viet is the name of the people, which covers the 54 different ethnic groups in the country. Nam means South. Viet Nam means the Viet people living in the South. To many people, Vietnam is not an unfamiliar name as it had been on the international press and media for such a long time. But what have been left in their minds are just images of war in a secluded corner of Southeast Asia, nothing more. So hardly does anyone know the meaning of the name and the long established history of that remote country. The name Vietnam came about when Emperor Gia Long desired to rename the country Nam Viet which was the combination of names of regions in Vietnam, including An Nam and Viet Thuong, and later change to Vietnam as seen today.
