Inhoudsopgave
Wat kun je halen uit DNA?
DNA is een verzamelpakket en de belangrijkste drager van ons erfelijk materiaal. Al onze celkernen bestaan uit 46 chromosomen, 23 van je moeder en 23 van je vader. Een DNA-onderzoek maakt het mogelijk je etnische achtergrond te ontdekken, een moord op te lossen, ziektes te bestrijden en genen te repareren.
Kan je zomaar een DNA test doen?
In theorie vormt het geen probleem om zonder toestemming van de moeder een vaderschapstest te doen. U kunt de DNA test online bestellen, wij zorgen ervoor dat u hem vlot in huis heeft. U ontvangt van ons de instructies en een envelop met daarin speciale steriele wattenstaafjes.
What is whole genome sequencing (WGS)?
Whole genome sequencing is a fast and affordable way to obtain high-level information about the bacteria using just one test. Currently, the process to fully characterize bacteria requires two or more scientists to perform four or more separate tests including PFGE. WGS will greatly improve the efficiency of how PulseNet conducts surveillance.
How can whole genome sequencing help us solve outbreaks faster?
Using whole genome sequencing, we have found that some bacteria that appeared to be different using PFGE are actually from the same source. This has helped solve some outbreaks sooner. Whole genome sequencing is a fast and affordable way to obtain high-level information about the bacteria using just one test.
What is meeting the challenges of whole genome sequencing?
Meeting the challenges of whole genome sequencing. In 2013, CDC began using whole genome sequencing to detect outbreaks caused by the deadly bacteria Listeria. Since then, this method has allowed scientists to: Solve more Listeria outbreaks while they are still small Identify new food sources of Listeria, such as caramel apples and ice cream
What are the steps in whole genome sequencing?
Scientists conduct whole genome sequencing by following these four main steps: DNA shearing: Scientists begin by using molecular scissors to cut the DNA, which is composed of millions of bases: A’s, C’s, T’s and G’s, into pieces that are small enough for the sequencing machine to read.
