Research CRISPR-CAS

Discussing several DNA techniques

Making homework

What are we going to learn today?

Today we will be learning: 

What several DNA techniques are and how they work. 

Crispr-cas

The most important technique to change DNA is crispr-cas. Work together with the person you are sitting next with and look up some information about it. Write about 3-5 sentences about what it can do, how it works and how it can help us. You have 5 minutes of time for this. 

CRISPR-CAS

CRISPR-CAS is a DNA technique with which we can change the DNA of an organism. These methods are called recombinant DNA techniques. 

Applications

Applications for gene editing. 

Organisms that have their DNA changed are called transgenes. 

DNA-investigation

While the DNA between us is the same for 99%; that last percent is really different. (1 in the 10.000.000.000)

That's why we can easily use DNA for forensic research. 

DNA-kinship

DNA tests

By testing your DNA you can find out where your DNA ''comes from'', and whether you have a hightened risk to get a certain disease. 

Genomics

Genomics is research of finding out where all of your genes are located and how they can be ''turned on and off''. This is very important for treating diseases and finding out wheter someone has a certain disease. 

eDNA

It is very important for ecologists to know how many species are in a certain ecosystem. We count this by catching them. Researchers are developing a new technique where they can see the DNA in sea water to estimate how many species are in the sea. 

Synthetic biology

Reseachers are so interested in how life work so we can replicate these techniques. Think about solar panels and lab-meat. One other application is making DNA ourselves so we can store data with it. 

Time to work!

The homework for next lesson are the exercises of paragraph 5.6. You have a big test about chapter 5 in 2 weeks.
