Viruses Flashcards
1
Q
Overall definition of viruses
A
Capsules of proteins that contain small amounts of genetic material (DNA RNA)
Reproduced only within host cell
2
Q
Structure of viruses
A
Two or three parts
Molecule and protective protein coat sometimes and envelope
Capsid protect chromosome
3
Q
Reproductive cycle
Of viruses
A
DNA: virus sheds protein coat DNA travels to nucleus DNA is copied and expressed by host
RNA: RNA serve as messenger to be translated to protein
4
Q
Lyctic and lysogenic cycles
A
Lyctic: virus replaced cells DNA replicates before bursting out
Lysogenic: DNA/RNA of the virus is duplicated along with cells
