Exam 9: Viral Genomes and Diversity

Proteins made by a ribosome reading through a transcript's stop codon without their own discrete ribosome binding sites

The Baltimore classification scheme is a useful way to categorize viruses based on their host infectivity.

Knowing the genome of Mu bacteriophage now enables researchers to locate where it incorporates into bacterial genomes.

Why is so much emphasis placed on the genomic composition (e.g.,ssRNA,dsDNA)of individual viruses.Provide examples to support your explanation.

Among the largest RNA genome viruses are ________ which contain a ________ genome.

Polyproteins made from human viruses such as poliovirus must be ________ in order to yield the required functional units of the virus.

Genomics analysis of recently isolated viruses indicate some viruses contain larger genomes than the some bacterial genomes.

To promote the translational activity of ribosomes in human cells for synthesizing viral proteins during viral infection,viruses

Integration of Mu DNA into the host genome is essential for

As a consequence of the immune system in humans recognizing dsRNA as foreign,

Which type of viruses can be directly used for translation?

The hepadnavirus DNA polymerase acts as which of the following?

A drug designed to inhibit reverse transcriptase activity would target

Despite viruses require a living host's metabolism to replicate,it remains unclear whether viruses existed before living cells.

Viruses are known to infect Bacteria,but no virus has yet been found that infects Archaea.

In T7,the proteins that inhibit the host restriction system are synthesized

Mu is a ________ virus with a ________ tail.

Nonfilamentous bacteriophage often can escape its host without lysing,whereas filamentous phage normally induce cell lysis once replicated inside their host.

How could overlapping genes in a positive ssDNA virus genome be predicted?

Most archaeal viruses identified appear to have DNA genomes.
