How can a reporter enzyme monitor transformation of host cells by foreign DNA in addition to a selectable marker?
A reporter enzyme monitors transformation of host cells by foreign DNA in addition to a selectable marker through insertional inactivation. It differentiates recombinants from non recombinants.
What are 2 reasons that the animal will not have the same DNA as its mother?
Because it will have some of its fathers DNA
How are DNa bands viewed?
DNA bands could be viewed using suitable colour marker dye like ethydium bromide. *that is only visible once illuminated with UV light
Where are the four nitrogen bases of DNA found?
The four nitrogen bases of DNA are naturally occuring amines and sometimes they are synthesized from amino acids in vivo.
What is the purpose of the ladder marker DNA?
DNA passes through a gel at different speeds depending on its size. The purpose of the ladder marker of a DNA is to make the passing of DNA possible.
Why a ladder DNA marker is usually run in parallel with DNA samples separated by gel electrophoresis?
The ladder DNA marker is the reference to indicate the position of a particular resolved band according to the molecular weight. Once the gel is solved, the Rf of the bands can be estimated in reference to the ladder DNA marker.

Which molecule for which phosphorus-32 is used as a radioactive marker?
Dna
Are the DNA molecules used for transformation of animal cell not require marker genes?
No
Do the DNA molecules used for the transformation of animal cells need marker genes?
yes
How is DNA typing done?
DNA typing is done by scientist, finding markers in DNA samples from things like blood, hair or bone samples. They are found by designing small DNA probes that bind to the complementary DNA sequence. These bindings will create a very unique, distinctive pattern for an individual. They then take this pattern and match it up to evidence samples that were found at the scene. If one marker is the same, it doesn't give strong enough evidence, because one marker is not unique to each person, but when there are four, five or more, then the probability is very high that the evidence sample and the DNA sample taken are from the same person.

What four nitrogenous bases does DNA contain?
The four nitrogenous bases in in DNA are adenine, thymine, cytosine, and guanine.
What name is given to a region of DNA that varies from person to person?
Restriction fragments are the region of DNA that varies from person to person. This is the key for DNA testing as many parts of the DNA string are the same for all mankind.
