Lifson Quizes 4 a, b, c Flashcards | Quizlet
The capsid coat of a virus is made up of what material? protein. The envelope of a virus is made up of. partly the membrane of the host and partly viral proteins. ... a. viruses contain DNA or RNA but never both b. viruses contain a protein coat c. viruses use the anabolic machinery of the cell More Information
Virus - The protein capsid | Britannica
The capsid surrounds the virus and is composed of a finite number of protein subunits known as capsomeres, which usually associate with, or are found close to, the virion nucleic acid. More Information
Capsid - Wikipedia
A capsid is the protein shell of a virus, enclosing its genetic material. It consists of several oligomeric (repeating) structural subunits made of protein called protomers. The observable 3-dimensional morphological subunits, which may or may not correspond to individual proteins, are called capsomeres. More Information

Viral Capsids Are Regular Arrays of One or a Few Types of Protein The nucleic acidof a virionis enclosed within a proteincoat, or capsid, composed of multiple copies of one protein or a few different proteins, each of which is encoded by a single viral gene. Because of this structure, a virusis able to encode all the More Information
7.8: Virus Structures - Biology LibreTexts
A virus particle consists of DNA or RNA within a protective protein coat called a capsid. The shape of the capsid may vary from one type of virus to another. The capsid is made from the proteins that are encoded by viral genes within their genome. The shape of the capsid serves as one basis for classification of viruses. More Information
What are viruses made of? - RockEDU
This protein coat is called a capsid, and the instructions for making the protein subunits of the capsid are encoded in the nucleic acid genome of the virus. The structure resulting from the combination of the capsid and the nucleic acid genome is called the nucleocapsid. A single, fully assembled, infectious virus particle is called a virion.

The capsid surrounds the virus and is composed of a finite number of protein subunits known as capsomeres, which usually associate with, or are found close to, the virion nucleic acid. More Information
Viral envelope - Wikipedia
A viral envelope is the outermost layer of many types of viruses. It protects the genetic material in their life-cycle when traveling between host cells. Not all viruses have envelopes. The envelopes are typically derived from portions of the host cell membranes (phospholipids and proteins), but include some viral glycoproteins.They may help viruses avoid the host immune system.

Viral Capsid The capsid, or core, is a protein shell surrounding the genome and is usually composed of protein subunits called capsomeres. The capsid serves to protect and introduce the genome into host cells. Some viruses consist of no more than a genome surrounded by a capsid and are called nucleocapsid or nucleocapsid (Figure 10.3. 1). More Information

Coronaviruses (CoVs) (order Nidovirales, family Coronaviridae, subfamily Coronavirinae) are enveloped viruses with a positive sense, single-stranded RNA genome.With genome sizes ranging from 26 to 32 kilobases (kb) in length, CoVs have the largest genomes for RNA viruses. Based on genetic and antigenic criteria, CoVs have been organised into three groups: α-CoVs, β-CoVs, and γ-CoVs (Table 1 ... More Information
Introduction to Viruses – General Microbiology
Viruses can be extremely simple in design, consisting of nucleic acid surrounded by a protein coat known as a capsid. The capsid is composed of smaller protein components referred to as capsomers. The capsid+genome combination is called a nucleocapsid. More Information
