General Informa;on
• Make the workshop interac;ve
• Don’t be afraid to ask ques;ons. Asking ques;ons is not a sign of stupidity. Those who ask lots of ques;ons will gain more from the workshop.
• Par;cipants will be expected to ‘present’ their group results and discuss them.
• We will have a QUIZ at end of each day: be prepared to answer ques;ons and to ask ques;ons.
• Keep a laboratory note book: A4 hardback notebook is provided. Keep it up to date. Record everything you do in the lab as you do it, methods, your thoughts and ideas, your results, and interpreta;on of results. We will display examples of par;cipants’ lab books during the workshop.
General Informa;on
Workshop objec;ve For par;cipants to acquire basic molecular biology and bioinforma;cs concepts and prac;cal skills that can be used for the advancement of research at their home ins;tutes
• Prac;cal skills and concepts in basic molecular biology tools
• Prac;cal skills and concepts in BFX, using DNA sequences obtained during the workshop • Experience the discovery process as a team • Establish basic mol biol and BFX at your home ins;tute
• Basic concepts of mol biol and BFX for understanding various contemporary areas of research and their applica;ons • Communicate with other researchers in mol biol • Links between researchers (posters) and with BecA

Learning molecular biology and bioinforma;cs through DNA barcoding
? ?
DNA barcoding is based on a simple concept. DNA barcoding is a taxonomic method that uses a specific short gene;c marker in an organism's DNA to iden;fy it as belonging to a par;cular species. In 2003, Paul D.N. Hebert from the University of Guelph, Canada, proposed the compila;on of a public library of DNA barcodes that would be linked to named specimens. This library would "provide a new master key for iden<fying species, one whose power will rise with increased taxon coverage and with faster, cheaper sequencing".
DNA barcoding
DNA barcoding: a new diagnos;c tool for rapid species recogni;on, iden;fica;on, and discovery. As of February 2013, the Barcode of Life Datasystems database included almost 2,000,000 barcode sequences from over 160,000 species of animals, plants, and fungi. h`p://www.boldsystems.org/

Organism is sampled DNA is extracted
Sequenced DNA is compared with sequences in a barcode database to iden;fy the organism
How Barcoding works
The PCR product is sequenced
a small region of DNA (the Barcode DNA) is PCR amplified
Applica;ons of DNA barcoding (1) Facilita;ng iden;fica;on and recogni;on of named (described) species:
• Plant leaves even when flowers or fruit are not available • Linking life history stages, genders • Differen;a;ng cryp;c species • Iden;fying gut contents (e.g. ;cks, mosquitoes, bi;ng insects) • Human and plant disease vectors • Agricultural pests • Biosecurity: detec;ng invasive insect pests at port of entry • Inventory of species in genebanks • Food (market subs;tu;on) • Bushmeat and illegally sold products of endangered species
(2) Surveying biodiversity; e.g., flagging poten;ally new (undescribed) species.
