Landmines in many countries worldwide remind us of dreadful wars in the past and these too still prey on innocent lives who accidentally step on them. There is an interesting research however on a genetically modified plant species, Arabidopsis thaliana which detects the presence of land mines through changing colors. In a particular study, a gene that turns-on the production of the red pigment, anthocyanin in the presence of nitrogen dioxide has been inserted in the genome of thale cress (A. thaliana). As the modified plant already renders a sensitivity to the presence of nitrogen dioxide gas, in areas where unexploded landmines exist, the leaves of these plants turn from green red, signaling the presence of nitrogen oxide gases released by these buried bombs (Nelson, 2004).

- Remdesivir is an antiviral drug used to treat SARS-CoV-2 infections. It is a broad-spectrum antiviral, meaning it has activity against many different viruses. Remdesivir can be incorporated into a new RNA chain as a virus replicates and can interfere with the viral replication machinery. Template RNA Elongation New RNA SARS-CoV-2 RNA polymerase Template groove Nucleotide entrance Nucleotides Remdesivir Figure 1. A representation of remdesivir and the viral replication machinery for SARS-CoV-2. 6. Figure 1 shows that remdesivir "mimics” an important component of RNA replication. Which specific component of RNA replication has a structure like that of remdesivir? 7. Propose a hypothesis about how remdesivir might inhibit the virus's replication process.arrow_forwardDrug resistance in a population of bacteria is inevitable for all of the following reasons EXCEPT.. O Bacteria share genetic material through gene transfer mechanisms of conjugation, transformation and transduction. OBacteria quorum sensing leads to the activation of drug resistant genes. O Bacterial drug resistance genes generally have inducible promoters that are activated when the drug is present. Bacteria mutate rapidly because of radiation and chemical mutagens.arrow_forwardThe ability of F+ cells, or Hfr cells, to transfer plasmid DNA to an F- cell is properly called: transversion transformation conjugation transduction transitionarrow_forward
