Viruses and Prions Flashcards
Capsid
Protein coat covering viral genome
Viral genome
Single nucleotide molecule; Either DNA or RNA
Lytic cycle
Viral reproduction that multiplies the virus and breaks open the host cell
Lysogenic cycle
Viral reproduction in which the genome enters the host cells chromosomes and does not destroy the cell
Prophage
Viral DNA in the lysogenic cycle
Viruses in animals
Outer membrane, glycoprotein spikes, and typically RNA genome
RNA replication
RNA replicated by viral enzymes to spread genome and create more viruses
Leaving the cell
Viruses leave by taking the host cells membrane
Plant viruses must pass the…
Epidermis (first layers of cells)
Plant viruses spread through…
Plasmodesmata (cytoplasmic connections between cell walls)
Retrovirus
Virus that makes DNA from RNA
Reverse transcriptase
Synthesizes DNA from RNA
Prions
Infectous proteins
What do prions do
They deform normal proteins and effect brain function
