Bacteria are often the preferred hosts for genetic engineering projects by splicing in novel genes from eukaryotes into plasmids, which are moved into competent bacteria. For instance, the gene for human insulin was isolated and moved into a bacterium, which can now produce the much-needed chemical. Previously, type 1 diabetics had to rely on professionals that gathered insulin from human cadavers, cows, and pigs. In order for this feat of genetic engineering to occur, researchers had to start with an unspliced mRNA transcript for h insulin. Agree/Disagree? Explain your response.

Genomic studies

Genomic studies (genomics) is the study of the whole genome of an organism. Using bioinformatics and high-performance computing, genomic researchers examined massive amounts of deoxyribonucleic acid (DNA)-sequence data to discover variations or mutations that affect drug response, health, or disease. Genomics is a much younger discipline than genetics, having only emerged in the last few decades as a result of technological advancements in DNA sequencing and computational biology.
