Viruses

micro bio chap 5

QuestionAnswer
complete viral particle- molecules of DNA/RNA enclosed in a protein coat Virion
Viruses that infect bacteria Viriod
Latent form of virus that lives with the host chromosome Provirus
satellite RNA virus that need a helper virus to infect host cell Virusoid
Proteinaceous infections agents that cause nuerodegenerative infection in human and animals prions
nucleocapsid- nucleic acid is surrounded by proteinaceous caspid made of protomers naked virus
have a flexible membrane around capsid. spikes are proteins inserted in the membrane enveloped virus
protomers are arranged in a long cylindrical rigid tube and nucleic acid is contained in it. Helical
these are made of ring like knob shaped units called capsomere which are made of 5-6 protomers. icosahedral
pox virus has an ovoid to a brick shaped exterior with a biconcave central disk which is the DNA Complex symmetry
phages that have a double structure with icosahedral head and a helical tail binal
protomers are arranged in a long cylindrical rigid tube and nucleic acid is contained in it. example: TMV virus Helical thise
adenovirus and polyoma virus icosahedral
phages that have a double structure with icosahedral head and a helical tail E.coli and some temperate phages
spikes on envelope peplomers
used for attachment and sometimes identification spikes
some have enzyme nueraminidase which helps in release of virions from host cell spikes
some have hemagglutinnin proteins that cause RBC to clump together spikes
attachment of virus to host cell viral multiplication step one
entry of viral nucleocapsid or nucleic acid viral multiplication step two
synthesis of viral proteins and nucleic acids viral multiplication step three
self-assembly of virions viral multiplications step four
release of progeny visions viral multiplications step five
virions do not randomly attach to host but are attached to the receptors on the host surface attachment
viruses can be tissue specific. example HIV viruses targets CD4 and CCR4 proteins in humans eukaryotic hosts

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
