1. micro satellite marker section of DNA with long variable number of
tandem
repeats of an even simpler sequence (i.e.,
dinucleotide or trinucleotide repeats)
2. mini satellite marker section of DNA with repeating units from 15 to
100
nucleotides long
3. CODIS Combined DNA Index System
4. What is CODIS 13 micro satellite loci and amelogenin (AMEL) to
deter- mine sex. Use in forensic DNA analysis
5. How many loci in CODIS 13, under each genotype is the expected
frequency
in a sample population, by combining the
frequency information for all 13 CODIS loci, one
can calculate that the frequency of this profile.
Any two samples with matching genotypes at all
13 CODIS loci are from the same individual.
