Skip to 1 minute and 0 secondsDr David, nice to meet you! Nice to meet you. I'm Natsumi. I brought this evidence from the crime scene, and I'd like you to have a look at all of them-- OK. --in the laboratory, please. OK. What we'll do, is we'll have a look at the items you've bought. We'll check them for some sources of DNA, see if we can find any. If we can, we'll then extract that DNA. We'll amplify out the particular areas we're interested in, and then that means that we can search it against the database and see whether we can find a suspect. OK? Well, if you want to follow me, we can get started. Yes please. Thank you. [FOOTSTEPS]

Welcome to Week 2 - Introduction to forensic biology


Welcome to the second week of the course. We’ve already come a long way, having learnt about the right way to gather and record evidence at a scene of crime.

This week you’ll delve into the hard science of evidence examination. You’ll discover the importance of DNA extraction, profiling and matching. The experts this week will lead you through the processes, making everything understandable and clear as you encounter the cutting edge techniques used today.

Enjoy this week, and be sure to share your thoughts in the Discussion board for this week.

Now watch the video. Bring the recovered metal bar and blood swab secured at the crime scene to Senior Scientist, Dr David Ballard and find out how to analyse those items for sources of DNA.
