Are viruses made of protein and lipid membranes?
A virus particle is composed of a nucleic acid that is surrounded by the capsid (which is the protective layer that is made out of protein). Some viruses can have lipid envelope however, not all viruses have a lipid envelope.
Does a virus have a protein coat?
Yes. All viruses are composed of a nucleic acid surrounded by a protein capsid. When the capsid is not present, the the infectious nucleic acid is called viroid. When the nucleic acid is not present, the infectious protein coating is called prion.
What two parts make up all two virus?
All viruses are composed of genetic material (either DNA or RNA) encased in a protein coat called a capsid. Some viruses also have an outer lipid envelope derived from the host cell membrane.
Is single-stranded DNA or RNA present in the genetic material of certain viruses?
Yes, single-stranded DNA or RNA is present in the genetic material of certain viruses.
What is the difference between capsid and envelope?
A capsid is a protein coat that encloses the genetic material of a virus, providing protection and shape. An envelope is a lipid membrane that surrounds some viruses, derived from the host cell membrane as the virus exits the cell. Not all viruses have an envelope, but all viruses have a capsid.
Which component is present in some viruses but absent in others?
Envelope

What additional protective layer of protein surrounds some viruses-?
The envelope.
Do viruses contain phosphorus?
Viruses do not contain phosphorus. They are composed of genetic material (DNA or RNA) encased in a protein coat, and sometimes a lipid envelope. Phosphorus is a key element in the structure of nucleic acids in living organisms, but viruses do not have the capacity to perform metabolic processes that require phosphorus.
Do virus composed of two parts?
Yes, many viruses are composed of two main parts: the genetic material and the protein coat. The genetic material can be either DNA or RNA, which carries the instructions for replication and infection. The protein coat, or capsid, protects the genetic material and helps the virus attach to and enter host cells. Some viruses also have an additional lipid envelope derived from the host cell membrane.
Does a virus have a protein coat?
Yes. All viruses are composed of a nucleic acid surrounded by a protein capsid. When the capsid is not present, the the infectious nucleic acid is called viroid. When the nucleic acid is not present, the infectious protein coating is called prion.

Is single-stranded DNA or RNA present in the genetic material of certain viruses?
Yes, single-stranded DNA or RNA is present in the genetic material of certain viruses.
The coats of viruses are composed of wjat?
The coats of viruses, known as capsids, are primarily composed of protein subunits called capsomers. These proteins assemble to form a protective shell that encases the viral genetic material, which can be either DNA or RNA. In some viruses, the capsid is surrounded by an additional lipid envelope derived from the host cell membrane. This structure is crucial for protecting the virus and facilitating its entry into host cells.
What nucleic acids are present in a virus?
Viruses are composed of two main parts: an outer protein covering called a capsid and an inside core of either DNA or RNA. Not both DNA and RNA. Some of these have an envelope over the capsid.
What organic molecules exist in all viruses?
All viruses contain genetic material, which is typically composed of either DNA or RNA. Additionally, viruses have a protein coat called a capsid that encloses the genetic material. Some viruses also have an outer lipid membrane envelope derived from the host cell.
What is the difference between capsid and envelope?
A capsid is a protein coat that encloses the genetic material of a virus, providing protection and shape. An envelope is a lipid membrane that surrounds some viruses, derived from the host cell membrane as the virus exits the cell. Not all viruses have an envelope, but all viruses have a capsid.
