Viruses

Host ________ such as DNA polymerase make many copies of the phage DNA and transcribe the genes within these copies into mRNA.

________: composed solely of a single- stranded circular RNA molecule a few hundred nucleotides in length.

________ does not code for proteins.

In the case of ________, the DNA provirus is not excised from the host chromosome.

________: genetic elements that replicate independently but occasionally integrate into host DNA.

________: small infectious particle that consists of nucleic acid enclosed in a protein coat called a capsid.

________ evolved from macromolecules inside living cells (maybe plasmids)

________: number of species and cell types that can be infected.

________: composed entirely of protein; converts normal proteins to abnormal form.

________ modify capsid proteins or serve as scaffolding.

Structure: ________ vary in shape and complexity.

________ integrates into host genome and may remain dormant for long periods of time.
