The genome of the domesticated dog,Canis familiaris,was sequenced in 2005.Using the dog as a model system provides insight into which of the following human disease states?

A drawback to using microarrays is_______ .

Personal genome sequencing assists with the recognition and determination of what?

A common first separation technique in 2D gels is isoelectric focusing.What property is isoelectric focusing taking advantage of?

Several years ago,scientists compared the genome of a wooly mammoth to that of an African elephant and found them to be 98.5% identical.This is an example of what type of "- omics"?

A newly sequenced gene is cloned and expressed in a bacterial cell.The bioinformatics databases suggest that this gene produces an enzyme that catalyzes the conversion of carbon dioxide to bicarbonate.After weeks of experiments,a scientist determined the enzyme has a completely different function.This is an example of_______ .

Transcriptomics requires the isolation of RNA to generate sequence data.If a scientist wants to use next- generation sequencing to perform their experiment which of the following is necessary?

In general,the organization of genes in bacteria is different from that in eukaryotes.In E.coli,approximately 27 percent of all genes are organized into contiguous,functionally related units containing multiple genes under coordinated control that are transcribed as a single unit.Such contiguous gene families are called_______ .

Genomes from several primates have been sequenced and annotated.These primates range from chimpanzee to Rhesus monkey to Neanderthal and modern humans.What is the advantage of having so many primate sequences available to researchers?

Nutrigenomics is the study of_______ .
