Can I have well-organized and accurate responses strictly for the following exercise please?

Nurses are now actively involved in COVID-19 interventions, and they will remain key players in stopping the pandemic with adequate assistance. Thus, they must be provided with a healthy work environment to empower their efforts to control and manage the outbreak. Such a work environment should be a judgment-free atmosphere for staff, where they will feel free to comment on accidents such as exposure to body fluids, other infection control risks, or reports of abuse, and to take prompt follow-up action such as providing counselling for staff members. First and foremost, occupational safety is key to nurses' work during COVID-19, as they are face-to-face with danger on a daily basis. The overarching duty of nurse leadership will be to ensure that the appropriate prevention and security steps are taken to reduce the dangers of the workplace. In this respect, it is important that hospitals have appropriate infection control procedures and personal protective equipment (masks, gloves, goggles, gowns, hand antiseptics, soap and water, and cleaning materials) in ample amounts for personnel who care for suspect or verified COVID-19 patients. Nursing supervisors should offer knowledge on workplace security, in addition to instruction and guidance regarding infection prevention and control and how to properly don, doff, and discard personal protective equipment. In this regard, staff members should also be guided on how to carry out regular self-assessments, and directed on how to follow quarantine or isolation measures, when indicated, to protect them, their families, and their community, as well as to safeguard their mental health and well-being.

1. Consider the fallacy of the following presumption in regard to iterative models.

 Presumption: Iterative Mechanisms are sequential and the ability to perform the next step is based on the previous step.

 

 Validity:

 The presumption is valid. Iterative mechanisms entail cycles of activities or steps which are done successively and the output of each cycle forms the basis of the next cycle. In the biological and computational domains, many processes are sequential and the next step depends on the results of the previous one. For instance, in iterative algorithms, every next iteration is somehow better than the previous one, and in biochemical processes such as DNA replication, each cycle depends on the preceding ones and each is completed successfully.

 

 2.

 

 Discussion:

 Z-VAD-FMK is a general caspase inhibitor which has been employed in experiments to elucidate the part performed by caspases in apoptosis. Caspases are a group of proteases that has been implicated in the process of apoptosis; this is the programmed cell death. Z-VAD-FMK is a broad-spectrum caspase inhibitor that covalently modifies the active sites of caspases and blocks their activity to cleave their substrates and thereby preventing apoptosis. This drug is employed to investigate the role of caspases in cell death and diverse diseases.

 

 3.

 Answer:

 

 In genetic algorithms an “offspring” is generated by combining the “genetic material from two parent solutions and the remaining part of the chain is “crossed over” to the prototype “solution”. In the process, ‘crossover’ and ‘mutation’ are made to bind with the model.

 

 Explanation:

 Genetic algorithms are based on processes that are modelled on natural evolution. Offspring solutions are created by crossover where parts of parent solutions are combined and by mutation where parts of the solution are randomly changed. These new solutions are then judged for their fitness and they are incorporated into the population to create better solutions in the next generations.

 

 4. That being the case, can it be assumed that in the double-stranded prototype, the two strands are separated before the oligonucleotide is toughened? Specify how the annealing is done.

 Answer:

 

 It is not right to conclude that double-stranded prototype separation happens before the oligonucleotide has become a tough.

 

 Explanation:

 In molecular biology, the process of annealing, literally means the joining of complementary strands of nucleic acids. The double stranded DNA which is to be amplified in PCR (Polymerase Chain Reaction) is heated to separate the strands. The oligonucleotides (primers) then hybridize to their complementary sites on the single stranded DNA (annealing). This occurs prior to the binding of the oligonucleotides to the target (denaturation of the strands). Annealing is done by cooling the reaction mixture and in the process the primers will hybridize with the sequence on the single stranded DNA.

 

 5. In the following the conclusion that has been made regarding synthesis of the second strand is false. In your explanation, mention the part played by the oligonucleotide, indicate what is supplemented.

 Deduction: 5’-3’ exonuclease activity is a necessity for polymerase.

 

 Falsification:

 The deduction is false.

 

 Explanation:

 In the second strand synthesis of DNA, the polymerase enzyme does not need 5’ – 3’ exonuclease activity. It is for this reason that the specific property that is required for this task in DNA polymerase is the enzyme’s capacity to catalyze DNA synthesis in the 5’ to 3’ direction. Oligonucleotides (Primers) are important because it provides the 3’-OH which is the only functional end needed by DNA polymerases for DNA synthesis. The 5’ -3’ exonuclease activity has functions that include; erasing of RNA primers during DNA replication but it is not required in the formation of the second DNA strand.

 

 6. Determine the proper sequence of transport of polypeptide in a secretory pathway.

 Answer:

 

 The ideal order of transport of a polypeptide within a secretory pathway is:The ideal order of transport of a polypeptide within a secretory pathway is:

 

 Rough Endoplasmic Reticulum (RER): Formation and the primary folding of polypeptides.

 Golgi Apparatus: More changes, organizing, and palletizing of proteins into vesicles.

 Secretory Vesicles: Transport of proteins from the Golgi to the plasma membrane of the cell.

 Cell Membrane: Fusion of vesicles with the membrane and release of the polypeptide; exocytosis.

 Explanation:

 Polypeptides are made on the rough endoplasmic reticulum where they are also folded. They are then sent to the Golgi apparatus where they undergo further modification and are packaged into vesicles that are secretory. These vesicles move the proteins to the cell membrane and the proteins are secreted out of the cell to the extracellular area.

 

 7. Explain in general what kind of organization is present in multicellular organisms.

 Answer:

 

 Cells are organized into a hierarchical structure:Cells are organized into a hierarchical structure:

 

 Organelles: Part of the cell which has different shape and size and have specific function (e. g. nucleus, mitochondria, ribosomes).

 Cells: The simplest structural and functional organizations of living organisms that perform activities including metabolism, growth, and reproduction.

 Tissues: Structures of tissues disposed in a particular form and made up of like cells whose functions are closely related (for instance, epithelial, connective, muscle, nerve).

 Organs: Organs which are made up of a number of tissues co-ordinated in order to perform a particular function (e. g. heart, lungs, liver).

 Organ Systems: Major systems of organs which are related and united to perform certain functions of the organism (for instance, cardio-vascular system, respiratory system).

 Organism: It is the whole organism which is formed by several organ systems, which are functioning in one organism to perform an entire living organism.

 8. Explain and describe the process of formation of electrophiles.

 Answer:

 

 Mechanism:

 

 Electrophiles can be produced from a number of chemical reactions in which a molecule gains a site that lacks electrons and thus makes the molecule to be highly reactive with nucleophiles. One common mechanism involves:

 

 Activation of the Electrophile: A molecule is activated through a process that generates a radical centre which carries fewer electrons. This can be done by the elimination of a leaving group or by the introduction of an electron withdrawing group.

 Formation of the Electrophile: The activated molecule forms an electrophile which is the species with a positive charge or partial positive charge that will attract nucleophiles.

 Reaction with Nucleophiles: Electrophiles are involve in a reaction with nucleophiles or species with high electron density such as in electrophilic aromatic substitution or addition reactions.

 Explanation:

 Electrophiles are made by making some molecules deficient in electrons and hence more likely to react with nucleophiles. For instance, the formation of carbocations or the introduction of an electron-withdrawing group generates a strong electrophile.

 

 9. Explain why it is right to conclude that many mutations can be provoked at one locus. Mention the factors that enhance this process.

 Answer:

 

 Justification:

 

 Some of the mutations may be caused due to the multiple factors or mechanisms that may act on the same nucleotide sequence and thereby cause multiple mutations at the same site.

 

 Explanation:

 Mutations can arise from various sources, including:Mutations can arise from various sources, including:

 

 Chemical Mutagens: Some of the agents such as alkylating agents can change the DNA bases at certain positions which in turn results in more than one type of mutation.

 Radiation: UV or ionizing radiation may produce various kinds of damage (e. g. thymine dimers, single and double strand breaks) at one and the same site of the DNA.

 Errors in DNA Replication: It can be seen that mutations occur when DNA polymerase makes errors during replication and repeated exposure or stress can aggravate this situation.

 10. Compare and contrast the body’s shield with electrophiles.

 Answer:

 

 Shield: Glutathione
