Class at Faculty of Science |
MB140P49

Syllabus

1. week: Basic terms, application of molecular biology into the forensic genetics, „ancient“ DNA typing methods (RFLP, VNTR, dot-blot), sérology vs. Forensic genetics, why DNA quality and quantity matters in forensic genetics, scientific bodies (ISFG, DAB, AAFS, SWGDAM,..), WHO is WHO in forensic genetics

2. week: Types of biological stains and the ways of their storage and processing, crime scene examination, collection of biological samples, contamination and counter-crosscontamination issues, body fluid examination, morfology of trichologic  material, fluorescent assays (FACS, FISH, …)

3. week: DNA extraction methods, differential extraction, automation, human specific and nonspecific DNA quantitation, degradation index,  inhibitor removal, , WGA (Whole Genome Amplification)

4. week: Polymorphic regions and repetitive sequences, mutations, specific instruments used by forensic genetics, short tandem repeats (STRs), single nucleotide polymophism (SNPs), mixed biological samples, chimerism, X-chromosome polymorphisms, low copy number (LCN)  samples, positive and negative samples, technical artefacts

5. week: Lineage markers on Y-chromosome (SNP, STR,..), mitochondrial DNA (D-loop hypervariable region, coding sequence, heteroplasmy,..), haplogroups and haplotypes, mutation speed of lineage samples, geographic origin of haplogroups, DNA and surnames, pathologies, DNA of famous (Adolf Hitler, Martin Bormann, Romanovci, Thomas Jefferson, Jesse James, Őtzi, St. Birgitta, Tutanchamon,…)

6. week: Statistical evaluation of DNA typing results, paternity index, familiar relationship, random match probability, likelihood ratios, individual vs. Group identification

7. week: CODIS, police DNA databases, public and research DNA databases, GDPR, reference sample sampling, mass screening, ethical and legal issues connected with sampling

8. week: The evidential value of DNA analysis, Innocence project, falsely negative and falsely positive DNA typing results, th ecommon errors, CSI effect

9. week: DNA identification of mass fatality incidents, multidisciplinary approach, specific requirements for DNA analysis of skeletal remains, contamination issues, casuistics (mass graves in BiH,
