Students have asked these similar questions
pick a specific disease that is currently a candidate for gene therapy—(a)briefly describing the gene mutation(s) and resulting disease symptoms, (b)brief description of a current gene therapy approach(es) for this disease. Has this approach shown any potential successes in disease treatment?
Genome annotation refers to ...
1.) lining up overlapping regions in short shotgun sequencing reads to assemble
larger contiguous DNA sequences (contigs/scaffolds).
2.) using long-read sequencing platforms (such as PacBio or Oxford Nanopore) to gather information about the epigenetic status of each region of a sequenced genome.
3.) the process of predicting which parts of a genome sequence code for functional products (such as protein-coding genes), what those products do, and assigning them names.
4.) sequencing messengeRNA measure the relative expression levels of genes in
one or more tissue samples.
the most efficient general strategy for whole genome sequencing is ?
(a) double the coding sequence after sequencing the proteins
(b) shotgun sequence and assemble based on overlaps
(c) identify mutations that affect glycolysis
(d) obtain recombinant DNA clone maps before starting the sequencing
(e) obtain comprehensive SNP maps before determining the order of DNA clone

- A number of advances have been made in biotechnology. CRISPR/Cas9 one of the most controversial, and has had a lot of media attention in recent years. It is a method by which scientists can precisely edit DNA sequences at exact locations. Benefits obviously include the potential to “repair” mutated genes that cause disease. In fact, preliminary results from one of the earliest clinical trials of CRISPR/Cas9 provide evidence that the technique is safe and feasible to use for treating human diseases. What other potential applications of this application do you see (you can use any organisms to illustrate your answer)? What are the potential dangers or downsides of using this technology?

- Because genetic engineering involves the modification of an organism's set of instructions, it has created a dilemma raising both moral and ethical concerns. For instance, a biotechnological company has found a way to produce rice that is immune to pests and diseases, which is vital for the establishment of food security. However, the methods that will be implemented are by splicing off the genes of endangered pandas using invasive procedures that may harm their population. Will you support this? Why or why not?
