There is a variety of reasons you would want to isolate D.N.A these include:

1. Medicine

- to test newborn babies for genetic disease by sequencing the relevant gene e.g. cystic fibrosis

- studying the gene involved in causing cancer to identify the mutation causing disease

2. Crime

- analyze forensic evidence to establish events and identify people present at a crime scene and the positive identification of a corpse

3. Food Safety

- trace the origin of an outbreak of food poisoning

4. Biotechnology

- isolate genes of interest and insert them into plants to give them: better test / pesticide resistance / increased nutrient value, or into bacteria and use them as 'factories' to produce high value products like the peptide insulin.

Hope that helped in some way!

The site where the old DNA strands separate and new DNA strands will be synthesized is called the?

The site where the old DNA strands separate and new DNA strands are synthesized is called the replication fork. This is where the enzyme DNA polymerase adds nucleotides to the growing DNA strand.


Can electrolysis be used to separate DNA fragments?

No, electrolysis is not typically used to separate DNA fragments. DNA separation techniques such as gel electrophoresis are more commonly used in molecular biology to separate DNA fragments based on size. Electrolysis is a process that uses an electric current to drive a chemical reaction.


What sites separate and replicate in DNA?

During DNA replication, the two DNA strands separate at the origin of replication, forming a replication bubble. Enzymes like helicase unwind the DNA strands, while DNA polymerase replicates each strand by adding complementary nucleotides. This process ensures that each newly formed DNA molecule contains one original strand and one newly synthesized strand.


Apply Concepts and enspIn general when would you use filtration to separate a mixture When would you use distillation to separate a mixture?

- Filtration is a method of separation when we want to separate solids from a liquid.- Distillation is a method of separation when we want to separate the components of a liquid mixture, relying on the differences between boiling points.


What is the role of heat in DNA extraction?

Heat anneals DNA strand i.e. separate two strands of DNA to build anti-codon to desired DNA strand

If all the hydrogen bonds in a DNA molecule were to break what would happen?

If all the hydrogen bonds in a DNA molecule were to break, the two strands of the DNA molecule would separate. This process is known as denaturation. The DNA molecule would no longer be able to function properly for processes such as replication or transcription.

What is the role of isopropanol in DNA extraction?

Isopropanol is used in DNA extraction to separate DNA from other cellular components. It helps to precipitate the DNA, causing it to clump together and separate from the rest of the solution. This allows for the isolation and purification of the DNA for further analysis.

Would chromosomal DNA spool if it was heated to 100 degrees?

If heated to a hundred degrees, chromosomal DNA would denature. Meaning the it would come apart and the complementary DNA strands would separate. One way to get DNA to spool (around a glass rod for example) is to remove it from the cell and precipitate it in solution. This can be done with with help of sodium chloride and isoamyl alcohol.
