To obtain DNA, you can collect a sample containing cells that contain DNA, such as saliva, blood, or tissue. Once you have the sample, you can extract the DNA using a DNA extraction kit or by following a DNA extraction protocol. This process involves breaking down the cell membrane and nucleus to release the DNA, which can then be purified and analyzed.
DNA Helicase unwinds and unzips the DNA. It separates the two strands of DNA so DNA replication can occur.
Recombinant DNA is a new form of DNA because it is created via introduction of the relevant DNA into the existing organismal DNA.
The biologist is studying the process of DNA replication, which is the process by which DNA is copied to produce two identical DNA molecules. This process involves DNA polymerase, which synthesizes a new DNA strand by adding complementary nucleotides to the original DNA template strand.
Ligase is used to join DNA strands together
You have DNA in your cell because you need DNA to be some one and you should have DNA in your nucleus
