Ch 27 Flashcards
Genome contains the complementary strand to the mRNA, SARS, measles Ebola, RNA virus
Negative single stranded viruses
Herpes, small pox, B19 parvovirus
DNA viruses
Viruses that infect bacteria
Bacteriophage
Phage infects bacteria, DNA is injected into cell and virus begins to replicate, cell accumulates many viruses and ruptures
Lyric cycle
Phage infects bacterium, viral genes are incorporated into host cells genome, virus genome is replicated when the cell replicates
Lysogenic cycle
When a bacterium incorporates foreign genes into its genome
Transformation
RNA viruses that transcribe its genes into DNA when infecting the host cell, HIV
Retrovirus
Enzyme that makes a DNA copy of the viral RNA
Reverse transcriptase
Genome contains the same sequence as the mRNa that will attach to the ribosome (template strand), HIV, polio, RNA virus
Positive single stranded viruses
AZT and protease inhibitors
HAART therapy
Reverse transcriptase inhibitors, prevents copying of viral DNA into RNA
AZT
Prevents the assembly of new viruses
Protease inhibitor
