- WRITE ABOUT A THEME: ORGANIZATION While virusesare considered by most scientists to be nonliving, they doshow some characteristics of life, including the correlationof structure and function. In a short essay (100–150 words),discuss how the structure of a virus correlates with its function.Question: How does the interaction of covalent w/ hydrogen bonds and the structure of RNA encourage this molecule to replicate its own self? -Please include words: triphosphate vs. monophosphate RNA monomer, ribose, phosphate, base, carbon 5/carbon 3, polymerization, A-U, G-C, template-directed polymerization, complement, complement of complement, replicaState 3 simple ways in which RNA polymerase is the same as DNA polymerase.
- Replication of many RNA viruses depends on RNA polymerase. The antiviral drug ribavirin does not inhibit the polymerase but instead increases its error rate. Explain how this affects the virus.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.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..

Based on this information, what would be the percentage of cytosine?Herpesviruses cause several skin diseases. Considering some features all of these conditions have in common, hypothesize what the viral DNA does after initial invasion of a host cell.The protein covering the central nucleic acid core of a virus. Protein coat of the HIV virus.

RNA onlyc. both DNA and RNAd. either DNA or RNAUnderstanding how this virus works can help us defend ourselves against other deadly influenza strains that arise. Critics of the research are concerned: If the virus escapes the containment facilities (even though it has not done so yet), it might cause another pandemic. Worse, terrorists could use the published DNA sequence and methods to make the virus for horrific purposes. Do you think this research makes us more or less safe?Viruses with reverse transcriptase enzyme can make a DNA copy out of its RNA genome. What implications can this capability do in health hazards?
