HIV encodes a number of small proteins such as tat and rev. I viruses with circular ds DNA genomes and infect eukaryotic cells. These viruses a. replicate their DNA in the cytoplasm of the cell. SNV a. is a negative sense, RNA virus. Please limit your answer to the space provided.
Cells produce mRNA by transcription of their DNA genomes.
In contrast, single-stranded RNA genome viruses have three different strategies with respect to viral mRNA production. Briefly describe the production of mRNA for each of the following viruses. The genome of poliovirus is itself a monocistronic mRNA that is translated into a polyprotein. The negative sense template of VSV is transcribed into five subgenomic mRNAs immediately after infection by the virion-associated transcriptase. The positive sense genome is reverse transcribed into cDNA, then into a double stranded proviral DNA which is integrated into the host chromosome.
