You digest 4 uL of plasmid DNA that is 50 ng/uL concetration in a total volume of 20 uL. You run 10 uL of the digest on teh gel. You then do a DNA purification protocol with a Zippy prep on the remaining digested DNA. You elute the DNA in a 25 uL. A 2 uL ssample has the concentration of 2 ng/uL. What is the DNA yield?
Bacterial Genomics
The study of the morphological, physiological, and evolutionary aspects of the bacterial genome is referred to as bacterial genomics. This subdisciplinary field aids in understanding how genes are assembled into genomes. Further, bacterial or microbial genomics has helped researchers in understanding the pathogenicity of bacteria and other microbes.
Transformation Experiment in Bacteria
In the discovery of genetic material, the experiment conducted by Frederick Griffith on Streptococcus pneumonia proved to be a stepping stone.
Plasmids and Vectors
The DNA molecule that exists in a circular shape and is smaller in size which is capable of its replication is called Plasmids. In other words, it is called extra-chromosomal plasmid DNA. Vectors are the molecule which is capable of carrying genetic material which can be transferred into another cell and further carry out replication and expression. Plasmids can act as vectors.

YIELD = How much dna came out of the column/how much DNA was loaded onto the column
Remember to subtract amount of DNA run on gel from total digested DNA to get hw much DNA was loaded onto the column
Amount that came out of the column equals the volume of the eluted DNA times the concentration of the purified DNA
