Binary Fission & Viruses Flashcards
(9 cards)
1
Q
What happens in binary fission?
A
cell contents doubles and then the cell splits in two
2
Q
What are viruses?
A
non-cellular infectious particles
3
Q
What do viruses contain?
A
capsid, DNA/RNA (nucleic acid core), protein molecules
4
Q
What is the virus’ nucleic acid core?
A
where their genomes are (DNA/RNA)
5
Q
What is a capsid?
A
the protein coat
6
Q
What are the attachment proteins?
A
protein molecules that are used to attach to host cells
7
Q
How do viruses attach to host cells?
A
using attachment proteins that are complementary to the receptor proteins on the surface of the host
8
Q
How do viruses make new viral proteins?
A
uses ribosomes in the host cell
9
Q
What are the stages of virus replication?
A
- attachment
- entry (injection of proteins)
- replications (using ribosomes)
- assembly
- Release (host cell bursts)
