Viruses Flashcards
What are the features of virus and describe the way is looks
Genetic material RNA
Reverse transcriptase ( enzyme )
Matrix
Lipid envelope
Capsid
Attachment protein
What does the RNA/DNA do
Codes for viral protein
What does the capsid do
Protects the RNA and DNA
What do the attachment proteins do
They bind to receptors on the cell
Are viruses living or non living and multicellular or acellular
They are acellular and non living as they don’t carry out the 7 characteristics of living and they aren’t made of cells
What does reverse transcriptase do
Produces DNA from RNA
How does a virus replicate
Uses attachment proteins on its surface to bind to complimentary receptor proteins on the host cell surface. They inject DNA or RNA into the host cell which divides as normal replicating the virus
