- Discuss how the genetic basis of life plays a central role in biotechnology. Further, ethical considerations aside, if DNA-based technologies became widely used, discuss how they might change the way evolution proceeds, as compared with the natural evolutionary mechanisms that have operated for the past 4 billion years.arrow_forwardJames Noonan and his colleagues (J. Noonan et al. 2005. Science 309:597–599) set out to study the genome sequence of an extinct species of cave bear. They extracted DNA from 40,000-year-old bones from a cave bear and used a metagenomic approach to isolate, identify, and sequence the cave-bear DNA. Why did they use a metagenomic approach when their objective was to sequence the genome of one species (the cave bear)?arrow_forward2b)An ancient gene underwent duplication during the course of evolution to yield two chain genes designated as δ and ε genes. Jessica’s final year project deals with the metagenomic studies of anfH homologous genes from freshwater lake samples in Kampar Eastlake. She successfully cloned and sequenced two partial anfH homologous gene sequences.BlastX analyses revealed that one of the DNA sequences showed highestsimilarity to AnfH protein from a Brazilian soil bacteria isolate while the second sequence showed highest identity to the AnfH protein sequence of a bacterium that was isolated from Tonle Sap, a freshwater lake in Cambodia. To determine their evolutionary relationship, she subsequently constructed a phylogenetic tree using the corresponding protein sequences. Describe the steps that are required toperform the analysis.arrow_forward
- Why is molecular technique (molecular genetics) the most advanced method used in studying genetics? In what fileds of sciences would this technique be applicable?arrow_forward1b) In 1995, the first free-living organism to have its genome completely sequenced was Haemophilus influenzae, a bacteria. In the following year, the baker’s yeast Saccharomyces cerevisiae was the first eukaryote genome sequence to be fully sequenced. The complete sequencing of the human genome and related organisms represent one of the greatest scientific achievements in the history of mankind. Write an essay on the importance of genome studies in general.arrow_forwardWhole-exome sequencing (WES) is helping physicians diagnosea genetic condition that has defied diagnosis by traditionalmeans. The implication here is that exons in the nucleargenome are sequenced in the hopes that, by comparison withthe genomes of nonaffected individuals, a diagnosis might berevealed. What are the strengths and weaknesses of this approach?arrow_forward
- The human genome holds an extraordinary amount of information about human development, medicine, and evolution. In 2000, the human genome was triumphantly released as a reference genome with approximately 8% missing information (gaps). In 2022- exactly 22 years later, technological advances enabled the gaps to be filled. This is a notable scientific milestone, leading to the resolution of critical aspects of human genetic diversity, including evolutionary comparisons to our ancestors. Discuss the sequencing technology used to resolve the human genome in 2005, its significant advantages and limitations?arrow_forwardThe human genome holds an extraordinary amount of information about human development, medicine, and evolution.

In other words, what would the next steps be if a natural scientist were to test or investigate your hypothesis? BI Genetic engineering has enabled researchers to gain a greater understanding of the disease and develop potential treatments, as well as identify genetic biomarkers and explore novel therapeutic approaches. It is likely to become an increasingly important tool for the advancement of Alzheimer's research.arrow_forwardGive three advantages ‘Next Gen sequencing’ has over Sanger sequencing for clinical microbiology.arrow_forward
