Virus

    Cards (10)

    • The genetic material of the virus is surrounded by a protein capsid which protects it from the environment and host immune system.
    • .The capsid (envelope) has "spikes", which represent attachment (envelope) proteins, sticking out of it. These attachment proteins help the virus attach to and infect a host cell.
    • A virus
    • Mesosomes - infolding of membrane which contains enzymes for cellular reactions
    • Flagella for movement
    • Cell wall - made from peptidoglycan
    • Pili/pilus - hair like structure which attaches to other bacterial cells
    • Plasmid - circular pieces of DNA, carries genes for replication
    • 70S Ribosomes for synthesizing proteins
