Viruses Flashcards
Q. Why would a DNA virus find it hard to replicate in neurones?
Neurones are non dividing cell, not undergoing DNA synthesis.
Therefore viruses that have a DNA Genome NEED carry with them DNA synthesis machinery and DNA replication enzymes!
Otherwise they won’t be able to replicate within neurones!!!
True or false:
Viruses need both structural + non structural proteins.
True!
Viruses … cellular … to target … of cells
Hijack
Trafficking pathways
Different types
What helps us to classify viruses?
By knowing the replication mechanism
Why is viral replication important?
Because it allows to make NEW viral protein, NEW viral genome and are assembled together to from NEW infectious viral particle that causes the infection inside the body!
NON- enveloped viruses contain all of the following components expect…
Peplomers!
Viral replication DOES NOT require…
Ribosomes provided by the VIRUS (they are provided by the host cell!)
What are 2 examples of sexual fungal spores?
Basidiospores
Zygospores
What 2 categories are NOT used in the classification of viruses?
Kingdom
Class
What is the intermediate host for SARS-CoV1?
Cats!
What is responsible for Dengue virus transmission?
Aedes mosquito species
What is responsible for the emergence of SARS-CoV1?
Bats
