Genomic DNA extraction: an introduction
Genomic DNA is abbreviated as gDNA or called chromosomal DNA because it is packaged into chromosomes. It is the genetic code that is present in every cell and is expressed in many different combinations that lead to different cell differentiation and expression. The DNA is transcribed into RNA molecules that become proteins with many different functions. Many laboratories around the world perform genomic DNA extractions. The purpose of the genomic DNA extraction is to separate the genomic DNA from the rest of the cell contents to study it. Genomic DNA is studied by those interested in learning about specific genes and learning from genomic sequencing.
