Episode 3: The DNA Episode

On this episode of RAZOR we delve deeper into our DNA and take a closer look at who we really are. Shini and Emma look at how we map and understand our DNA and why it&aposs not as clear-cut as you might think. 

The Human Genome Project was one of the most ambitious projects undertaken by science. An international team of scientists spent 13 years mapping our genetic data; pinpointing and laying out the sequence of all our genes.

However, there is a problem.  Seventy percent of its first DNA sequence came from the genetics of just one man while the rest came from about 50 other volunteers. Their data formed the backbone of the Human Genome Project&aposs first DNA sequence which has since become a reference; the standard to which every human DNA sequence is compared. 

Shini speaks to Dr. Julia Wilson from the Wellcome Sanger Institute about the lack of diversity in the project could be holding us back [01:54]. The RAZOR team goes further and investigates exactly how the “mapping” of the human genetic sequences happen [04:02]. To do this she speaks to Sumit Jamuar, the CEO of Global Gene Corp, a company that is spearheading efforts to diversify genomics by collecting genetic data from India.

The RAZOR team also looks at a new company that has found a way to look at how DNA testing can help us make better nutritional choices on a day-to-day basis. DNA Nudge is a company that focuses on on-site DNA testing that could highlight genetic predispositions and help their customers to adapt their lifestyles accordingly. 

Jo Colan went to investigate exactly how the company plans to do this [09:52]. Jo also speaks to the founder of the company Chris Toumazou who talks about the deeply personal inspiration behind the company [14:30].
