- The term _________________________________ means pertaining to a virus. viral virileBacillus anthracis (Anthrax) Shape and arrangement of your pathogen Bacillus shape and Streptobacilli arrangement Type of flagella, number and correctly named arrangement of the flagella (example: monotrichous) My pathogen is one of the few in its specie that is not motile. It contains one flagellin gene, however four essential proteins contain point mutations and frameshifts. Therefore, the flagella are nonfunctional and the organism lacks motility; Atrichous. Capsule or not (If yes, describe what is it made from) Yes. It is made of poli-y-D-glutamic acid (PGA). According to Frontiers in Immunology, “Bacillus anthracis poly-γ-D-glutamic acid (PGA) capsule is an essential virulent factor that helps the bacterial pathogen to escape host immunity.” Gram staining status OR acid-fast stain cell wall description. Explain why your pathogen has this status by describing your pathogen's cell wall structure. Gram positive-…Answer the following 1.Are viruses living or non-living organisms? 2. What is the difference between HIV and AIDS? 3. HIV is classified as a retrovirus. What are retroviruses? 4. In your own words, provide a short summary of the HIV replication cycle. 5. Why is reverse transcriptase an important enzyme in the replication cycle of HIV? 6. In the chapter about enzymes, we have discussed how drugs are basically inhibitors. There are currently a multitude of Antiretroviral therapy (ART or ARV) options available to people living with HIV (PLHIV) so that the viral replication is suppressed and does not progress to AIDS. What do you think these drugs target? Discuss briefly. 7. SARS-CoV-2, the virus that causes CoVid-19, belongs to the Coronaviridae family. Viruses under this family have a genome made of single-stranded positive-sense RNA. Is this similar to the viral genome of HIV? If so, do you think that – in theory – they would have similar replication cycles? 8. In your own opinion, do…
- QUESTION 5 Which characteristic correctly describes retroviruses? The are made up of only a single protein They can only reproduce by infecting bacteria They have a single-stranded DNA genome that acts as a template for DNA synthesis They have a single-stranded RNA genome that acts as a template for DNA synthesisplease tell me how bacteriophage and animal viruses multiply. please add both lytic and lysogenic cycles for bacteriophage, all steps, and the outcomes of both. For animal viruses, please include all steps and briefly explain the differences between their nucleic acids. i am having a hard trouble understanding this information if you could please explain in way where a child would understand it that would be amazing3. The table on the last page compares for each of four different proteolytic enzymes the chemical bonding structure of a classical substrate with the structures of two competitive inhibitors. For each substrate structure an arrow indicates the position of the scissile bond, i.e., the bond that is cleaved through catalytic action. For each enzyme, one of the inhibitors is a classical competitive inhibitor while the other is a transition-state inhibitor analog. While ordinary competitive inhibitors are associated with (dissociation) inhibitor equilibrium con- stants of ~10-3 to 10-6 M, transition-state analogs exhibit inhibitor constants ≤ 10-⁹ M. (a) For each enzyme draw a circle around those parts of the substrate that account for specificity of substrate recognition. (b) For each enzyme identify the transition-state inhibitor analog by drawing a circle around it and give a brief explanation of why it mimics the structure of the transition-state species. (c) Draw a "generic"…
