- Biology 1. There is evidence to dispove Crick's (1958) Central Dogma of Molecular Biology. one such evidence is how the coronavirus replicates genetic information. Explain fully how this process disproves Crick's Central Dogma 2. Describe how subgenomic RNAs are unique physically compared to regular RNA strands. Explain fully the benfit of this adaptation for viruses..The nucleic acid of a virus isa. DNA onlyb. RNA onlyc. both DNA and RNAd. either DNA or RNAOrigins of viruses. Exactly how and when did different groups of viruses originate?
- Part B - Viral Classification: The Baltimore Scheme The Baltimore classification scheme is based on the relationship between the virus' genome and its mRNA. For the following choices, indicate which viruses would fall into each classification: 1) require reverse transcriptase to copy the information in their own genome to DNA; 2) can replicate and be transcribed in the same manner as the cell's own genetic material; and 3) a replicative form of DNA must be produced and is used for both replication and transcription. Drag and drop choices to the bins they describe. double-stranded DNA viruses Requires reverse transcriptase double-stranded RNA viruses retroviruses double-stranded DNA viruses that have an RNA intermediate Functions similarly to cell's own genetic material plus-strand RNA viruses minus-strand RNA viruses Reset Help plus-strand DNA viruses Uses a replicative form of DNAneed a good answer for this question.

- Fill in the blanks. The parentheses after each blank represent the choices for the blank. Scientists already knew that a special type of virus called a bacteriophage inserts genetic information into a bacterial cell in order to force the bacterial cell to make more bacteriophage viruses. What scientists did not know, however, was whether that genetic information is carried by the _____________ (proteins, DNA) covering the outside of the bacteriophage virus or by the _____________ (proteins, DNA) inside the bacteriophage virus.You are studying a new retrovirus. The viral protein (X) appears to play a role in the export of the viral genomes to the cytoplasm. Protein X brings viral DNA to the cytoplasm and returns back to the nucleus after genome export is complete. Researchers have developed a new drug for the virus. Following treatment with the new drug, the viral protein stays in the nucleus and cannot export the viral genomes. What is the most plausible and logical function of the drug? Use your knowledge of nuclear transport to answer this question. O A. The drug inhibits the binding of the viral protein and the viral genomes to the import receptor. B. The drug inhibits the binding of Ran-GTP to the nuclear export receptor in nucleus. C. The drug promotes the Ran GAP activity. D. The drug blocks the NLS on the viral protein.Viruses with negative sense RNA genomes typically, make proteins by: (Ignore retroviruses, and the unusual characteristics of coronaviruses) Translation of short RNA transcripts generated by RDRP Generating a DNA copy, which is then transcribed by host RNA polymerase. Translation of the viral genome by host ribosomes. Production of a polyprotein, which must be cleaved into smaller proteins. Generating a negative sense genome copy, which is then translated by host ribosomes.
