Question

(3 pts) Describe which types of macromolecules the following components of human viruses are usually made of:

1. 1. Capsid -
2. 2. Genome
3. 3. Envelope -

Answer 1

Capsid : it is made of proteins. Capsid is the protein shell that houses it's genetic material. It has oligomeric structural subunits composed of protein.

Genome : it is made of either DNA or RNA. These molecules could be double or single stranded. Every viruses consists of a nucleic acid genome. The capsid shields the genome.

Envelope : it is made up of phospholipid bilayer & proteins. The lipds are derived from the cell membrane of the host. We usually consider the envelope as a "lipid envelope".
