Getting to Know our DNA
Secondary | Health | Views: 920
Consider the following questions and then watch the video by Dr Giulia:
- Why does DNA make us all diverse?
- Where are DNA and chromosomes located?
- How are humans mostly identical, what are the percentages of identical DNA and reasons why.
- What conditions come as a result of ‘mistakes’ in the sequence of DNA, chromosomes, or genetic disorders.
- What is DNA sequencing? Who was the famous scientist linked to the DNA sequencing process and what was his contribution.
- What can DNA sequencing be used for? How does the process help in creating bespoke medicines and treatments?
- DNA can also be used in forensics – what process takes place to extract DNA and how does this help determine a guilty suspect?
- Another forensic application is ancestry – DNA analysis lets us trace back generations. How does this work?
Now you've watched the video try the following tasks:
- Create an annotated diagram of DNA, based on Giulia’s description in the video
- Add functions to your diagram as described
- Describe the human genome.
- Name the nucleotides that can bind together – there are only certain possibilities. Use the Base Pair Rule.
- Giulia describes some techniques that are used in diagnosing mutations in genetics. Research any of these which interests you.
- Create a case study, outlining the process from DNA sequencing, to the creation of a bespoke drug, to how this drug treats the condition.
