The opinion about the access of databases of the genome, gene and protein sequences coupled with recombinant DNA (deoxyribonucleic acid) technology to only authorized persons, not to everybody. Introduction: Recombinant DNA technology (RDT) is a DNA-based technological application that uses living organisms and biological systems. RDT was started in the 1970s by Paul Berg, who made first recombinant DNA. The practice of scientists and researchers reach upto the development of genetically modified organisms that provide valuable products like high protein content through single cell protein and large-scale therapeutic protein formation (interferons, insulin hormones, and vaccine). An increase in applications of RDT may lead to cause an increase in mutagenic strain formation, multiple drug resistance in infectious agents of disease, etc.

Today, it is easy to make transgenic plants and animals. What are some important safety and ethical issues raised by this use of recombinant DNA technology? Explain your answer.

1A) Which of the following best explains Griffith’s transformation experiments? Two strains of S. pneumoniae were used for the experiment. Griffith injected a mouse with heat-inactivated S strain (pathogenic) and living R strain (non-pathogenic). The mouse died and living S strain was recovered from the dead mouse. From this, it was later concluded that that mutation occurred in the DNA of the R-strain cells thus transforming them into a pathogenic S strain. Two strains of S. pneumoniae were used for the experiment. Griffith injected a mouse with heat-inactivated S strain (pathogenic) and living R strain (non-pathogenic). The mouse died and living S strain was recovered from the dead mouse. From this observation, it was later concluded that external DNA from the inactivated S strain was taken up by the R-strain cells thus transforming them into a pathogenic S strain. Two strains of S. pneumoniae were used for the experiment. Griffith injected a mouse…
