6) The figure that follows shows DNA fingerprint analysis of the genomic DNA from semen associated with a rape (***) and from mouth swabs (somatic cells) of individuals 1-4. This analysis involves the PCR-amplification of six SSR loci, each from a different (nonhomologous) chromosome. All PCR primers used are 20 nucleotides long; the primers for each locus have fluorescent tags in a locus-specific color. In the gel, some bands are thicker than others because relatively more of the corresponding PCR product was obtained.

The figure that follows shows DNA fingerprint analysis of the genomic DNA from semen associated with a rape (***)
and from mouth swabs (somatic cells) of individuals 1-4. This analysis involves the PCR-amplification of six SSR
loci, each from a different (nonhomologous) chromosome. All PCR primers used are 20 nucleotides long; the
primers for each locus have fluorescent tags in a locus-specific color. In the gel, some bands are thicker than
others because relatively more of the corresponding PCR product was obtained. The figure has dots aligned on
both sides that you can use to compare the sizes of the bands using the edge of a piece of a paper as a guide.
