Viral Genome and RNA's

1

How does a retroviruse reproduce?

1

Reverse Transcriptase is vital for RNA retroviruses to replicate

1

The viral protein P is used for what?

1

Gag is the gene for envelope proteins

1

Which of the following can be directly translated?

1

What protein converts viral genomes into a version host cells can transcribe?

1

The Transcriptosome is the cell repetoire of proteins

1

What is the role of enhancers?

1

Name the types of enhances possible

1

Introns can make up to 2% of the gene

1

Assuming the middle segment is an intron, what is found at the 5' and 3' splice sites of the intron?

1

How is the 5' intron splice site cleaved?

1

The 5' is cleaved and the intron loops on itself- what removes the intron totally?

1

What is the roles of snRNA?

1

Twintrons are introns within introns

1

Which is spliced out first?

1

GpG islands are found near transcriptionally inactive human genes

1

Name the two theories concerning introns

1

What does snoRNA stand for?

1

snoRNA causes RNA to be acetylated

1

SnoRNA binds to the RNA to be modified

1

What can SnoRNA binding lead to?

1

There are few miRNA's, but they are very large

1

What is the role of miRNA

1

Once the miRNA is transcribed, what structures form?

1

What enzyme have these miRNA precursors NOT been cut by?

1

Once complete, where do these miRNA structures do?

1

siRNA stands for Short Interfering RNA

1

What is the main role of siRNA?

1

Where and to what does siRNA bind?

1

siRNA binds to mRNA in a double stranded form

1

Which of the following could be used as a gene therapy?

1

This RNA gene therapy works by making a dsRNA version of a gene in the cell; this will be cleaved to siRNA which will destroy ALL mRNA for that gene
