So here’s my third video to the mini series, introducing the idea of genetic engineering in a way that hopefully won’t sound as scary as some people might find the idea.
Genetic engineering is a wonderful tool allowing us to take genes from a human and put them into bacteria. Because every organism’s genetic code is made up of the same As, Gs, Cs and Ts the bacteria can interpret the genes and make the protein products we need. Also, because bacteria are so small and multiply so often, we can have a bacteria factory making things like insulin that we can use to treat people.
I was able to have a go at genetic engineering at university to make bacteria produce a blood thinner and the fact that a whole class of 3rd year students could do this successfully without ever trying the technique before is incredible and shows how far we’ve come in using genetic tools to treat medical conditions successfully.
What’s also great is that the protein made from the gene is a human version, not a bacterial version, as the original gene is from humans. This cuts out a whole number of potential problems!
So have a look at my video and let me know what you think!
A quick additional note: if you do download the adobe voice app, they’ve selected my second video in the series as part of their inspiration feed on the homepage of the app! So you’ll be able to see that within the app as an example video!

This is the second video in my back to basics series, this time introducing the idea of genes being regulated differently in different cells. There’s more to it then just off or on but the concept is fundamental, especially in developmental biology (my broader field of work).
This time round with the video I decided to try and use the images that are readily available to any user to see how far I could stretch the app to my needs, and I think it worked out quite well for a non-specialised app!
Have a watch and let me know what you think. The video still stays along the ks4 science curriculum guidelines so hopefully it can be a useful resource.
I caught wind of a new app for my ipad called adobe voice and straight away was inspired to start creating mini video stories describing the fundamentals of genetics. Hopefully I’ll complete this as a mini-series that could be used as a resource in a classroom (as I’m following key stage 4 genetics lesson guidelines) or even just for someone who’s interested in getting the basics right. Here’s my first go, and I have to be really complimentary of the software as it is so easy to create beautiful and professional looking videos. However please excuse my cartoon drawings!

(Adobe Voice isn’t supported as part of the embed feature in WordPress as of yet so please follow the link to the video!)
As an application to describe and explain scientific ideas (and anything else to be honest!) it really is worth having a look at, especially as it’s free!
