Can a virus make its own food?

Answer 1

Virus don't need food at all. They are just some DNA o RNA coveres with a protein capsule. They have some receptors that match with living organisms Membrane proteins, lipids or carbohydrates. When they find this receptors the DNA or RNA inside the capsule is transfered to the Cytoplasm, once there some specific enzymes will transport the DNA to the Nucleus in order for it to be transcribed and then to the Rybosomes to sintetize more of this proteins. The RNA virus just gets its RNA to a Rybosome and profuce this proteins. Virus cannot reproduce without infecting a living organism's cell.

Answer 2

They can not directly synthesize proteins themselves since they lack the machinery. Virus infect its host and integrate its genome into the host. The most system then recognize virus as its own and helps to synthesize viral proteins.

Answer 3

Protein making can be referred as protein synthesis inside the cell. When there is a protein coding mRNA is expressed, the protein synthetic machinery (that are made up enzymes which are proteins and other molecules) can translate the message from RNA to protein.

Answer 4

Proteins don't make proteins directly, although they are an integral part of the process. Some proteins are enzymes -- biological catalysts -- which help in all aspects of protein synthesis. For example, RNA polymerase (an enzyme) transcribes DNA to RNA so it can be sequenced into a polypeptide. Ribosomes (protein-rRNA complexes) also help build the strands. However, enzymes cannot do it all; nucleic acids are needed to code for the sequence of amino acids.

Answer 5

Viruses are not made of cells. Many scientists do not think a virus is a true living thing.

Answer 6

Viruses are known to make their own proteins from the virus genome. They also have the ability to encode two different protein types.

Answer 7

yes
