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.
A friend of yours who works at a biotechnology start up company has computationally designed three new proteins that she thinks might be able to prevent and possibly reverse cancers if they could be expressed/transported in the right location in human cells. If this works, the company will be worth billions and everyone who works there will be rich. Not to mention curing cancer…
The plan is to use a genetically modified, harmless virus to deliver the DNA genes for these three proteins. This should result in the transcription of mRNA and translation of the three proteins. The trick is getting the proteins to go to the right places in the cells so they can interact with the right cellular pathways.
The first protein is a transcription factor that binds to DNA and should shut down transcription of cancer promoting genes by binding to their promoters. The second is a protein that interacts with electron transport chain proteins to reduce the output of reactive free radicals in…
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?
