09:28Explain differences between whole-genome sequencing (WGS) and whole-exome sequencing (WES), and describe advantages and disadvantages of each approach for identifying disease-causing mutations in a genome. Which approach was used for the Human Genome Project?
Describe the human genome in terms of genome size, the percentage of the genome that codes for proteins, how much is composed of repetitive sequences, and how many genes it contains. Describe two other features of the human genome.
Describe the significance of the Genome 10K project.
It can be said that modern biology is experiencing an 'omics' revolution. What does this mean? Explain your answer.
The Human Genome Project has demonstrated that in humans of all races and nationalities approximately 99.9 percent of the genome sequence is the same, yet different individuals can be identified by DNA fingerprinting techniques. What is one primary variation in the human genome that can be used to distinguish different individuals? Briefly explain your answer.
Recall that when the HGP was completed, more than 40 percent of the genes identified had unknown functions. The PANTHER database provides access to comprehensive and current functional assignments for human genes (and genes from other species).
Go to http://www.pantherdb.org/data/. In the frame on the left side of the screen locate the 'Quick links' and use the 'Whole genome function views' link to a view of a pie chart of current functional classes for human genes. Mouse over the pie chart to answer these questions. What percentage of human genes encode transcription factors? Cytoskeletal proteins? Transmembrane receptor regulatory/adaptor proteins?
