True/False   u

True or False? Viral mRNAs lacking a 5' cap use an internal ribosome entry site (IRES) to initiate

translation.   ‘

True or False? Genome replication of most DNA viruses occurs in the nucleus of the host cell.

True or False? Approximately 8% of the human genome consists of defunct endogenous retroviruses (HERVs).

True or False? RNA polymerase III is responsible for synthesizing cellular mRNA that is translated by ribosomes.

True or False? Host toxicity is of minimal concern when developing ^tiviral drugs.

Short Answer

Glycosylation and phosphorylation are examples of ______that can be made to host viral proteins.

17.   ____ is remodeled or reorganized by viruses for entry, movement, and release of new virus particles.

Receptor-mediated endocytosis of viral particles involves the formatipn of invaginations in the cell membrane coated with_______

Because the viral RNA-dependent RNA polymerase lacks_______, the mutation rate in RNA viruses is relatively high.

The _____ approach for antiviral drug development involves researching the history of traditional medicines used in different cultures to treat diseases.

Explanation / Answer

1. the best method for estabilishing one step growth curve is the plaque assay because it tell us how many bacteriophage are active and growing.

2. the viral genome whose replication occurs exclusively in nucleus is the one that has only DNA therefore it would be the dsDNA

3. the filament and spherical forms of HBV contain nucleic acids

4. yes viral particles use IRES sites to enter and initiate translation.
