As a scientist working for an antibioterrorism task force,you are asked to evaluate some biological samples for presence of Yersinia pestis,the organism that causes plague.After confirming that the samples did,indeed,contain Y.pestis,you instruct your team to begin sequencing the strain.Given that the genome sequence of Y.pestis is already known,why did you instruct your team to sequence this strain?

A transgene is

Inactive genes that have lost their function due to mutations are called

Mobile bits of DNA that can jump from one location on a chromosome to another location are called

Some regions of chromosomes remain highly condensed,tightly coiled,and untranscribed throughout the cell cycle.These regions are referred called

________ are silent copies of genes that have been inactivated by mutations.

_________ is another term used to describe genome science.

Homologous regions of DNA can vary slightly in base-pair composition among individuals in a population.When a homologous stretch of DNA is cut with restriction enzymes in different individuals,fragments of different lengths are produced.These fragments are called
