In lane 1, a size standard was loaded, which contained a mix a DNA fragments known to be 1000 bp, 700 bp, 500 bp, 200 bp, and 100 bp.  In lanes 2-4, human samples the have undergone PCR reactions with PV92 primers have been completed and loaded into these wells. When the gel was run and stained, the following photograph of the gel was taken. Click on the lane (2-4) which shows a result consistent with a genotype of +/+ (homozygous for having the PV92 Alu insertion).

Genome annotation

The technique of linking biological information to genome sequences is termed genome annotation. Gene annotation is the method of identifying gene locations and coding sections. It helps us understand what these genes are doing in the body through establishing structural characteristics and linking them to the actions of various proteins.
