Question

1. Research a genetic disease that may be cured through the use of genetic engineering. What techniques are being explored to correct the problem? How do concerns of designer embryos stem from this technology?

2. How can DNA be fragmented into very specific sections?
3. What is one practical lab application for cutting a DNA sequence into specific segments?
4. Where do restriction enzymes come from? What is their function in nature?
5. How are restriction enzymes used when performing gel electrophoresis?
6. Investigate one way in which electrophoresis is used in medicine today. Write one or two paragraphs to explain your findings. Include references to information sources used.

Answer 1

There are many disease, which are cured using genetic engineering, for instance cancer.

DNA can be fragemnented into very specific section by using restrictions sites, these are the sites spread through out the sequence and we can cut DNA by using specific DNA restriction site and endonuclease.

DNA cuting is very crucial,for instance when you have to insert your target gene into a different organisim, then you need to cut that target gene first.

Restriction enzymes are present in microorganisms, like bacteria and bacteriophage. Their normal function is protection to the bacteria against any invading pathogen.

In order to perform gel electrophoresis, you need to cut DNA so that it can run on gel, also when you need to compare something or when you need to know molecular mass, you need to perform restrictions digestion then run it on gel.
