Here, it is taken up by the fish's genome and ultimately the DNA is present in cells throughout the body of the fish.
The researchers have identified three versions of the supergene, in all of which a certain segment of DNA is present in reverse order to the usual sequence.
Where trace levels of DNA of the wrong species, particularly pig, have been found in beef, the most likely explanation is that they have been contaminated either by failure to clean production lines thoroughly enough between different processing, or that the DNA is present in protein additives widely used in the industry to bulk out cheap so-called value or economy ranges.
In many bacteria the DNA is present as a single circular chromosome, although some bacteria may contain two chromosomes, and in some cases the DNA is linear rather than circular.
However, when target DNA is present, the HCR between the two hairpins is triggered.
The compositional maps or images (Figure 4) show that DNA is present in higher amounts than protein in each chromosome.
As a result, the DNAzyme sequence is produced by amplification only when the target DNA is present in the sample.
When this probability, P RMNE), is low, one can conclude that the suspect's DNA is present in the DNA mixture.
Overall, this suggests that fungal DNA is present in the embryo and is propagated throughout the tissue culture process, also indicating that the fungal microorganisms present are viable.
If a piece of anthrax DNA is present, it will bind to two probes on the chip, completing a circuit so electricity will flow to mark its presence.
As time proceeds one sees more and more half-labeled DNA, until at one generation time only half-labeled DNA is present.
