In the normal course of events it should not. If alcohol were consumed and then nothing else was consumed (so nothing could cleanse the mouth) and the body were in a state of mild to severe dehydration prior to consumption (completely unable to produce saliva) then it would be very remotely possible that a trace might remain.
Basically, the answer is no.
It's not that kind of test. So, no - it is only collecting tissue samples and the inside of the cheek is the easiest access.
Depending if it has a panel for it or not, yes it can but most likely they wont test for it.
Not if you drank it within a day or so.

When collecting DNA samples using buccal swabs (cheek swabs), and two swabs from separate donors touch, this can cause a contamination. I work for Identigene DNA testing center. When this happens and the swab is ran for analysis this would bring up two profiles on one swab. If this happens, we can not verify which profile is the correct profile, so we would order a recollection at that point (no extra charge).
A prenatal DNA testing can be done between the 12th -25th week of pergnancy. The first option is by extracting amniotic fluid from the mother and collection mouth swab samples from the father. There is also a non-invasive prenatal DNA testing which only involves extraction of blood from the mother and mouth swabs from the father.
The cells of the inner cheek are dislodged easily and replaced frequently, so they are a convenient source of DNA.
With a DNA kit you can use the swabs and a sample of your saliva to see if someone's DNA matches another person. This is often used to determine paternity of a child.
Long-term alcoholism has carcinogenic effects that cause damage to DNA, if that's what you mean. The WHO (World Health Organization) classifies alcohol as a Group 1 carcinogen. Unless you were looking for genetic damage due to alcohol, a DNA test wouldn't be ideal for testing alcohol usage.
The child's DNA samples can be collected with the use of mouth swabs included in a DNA collection kit. For the samples of the father from the US he may use cotton buds rubbing them on the left and right cheeks and placing them in a paper envelope labeled with name, date of birth and sex. When the samples are complete a DNA paternity analysis can be done.
because of the negative charge in alcohol and the dna. it makes the dna not stay together.
According to me, we use alcohol because DNA is insoluble in alcohol, it aggregates together, giving a pellet in centrifugal and we can see a precipitated DNA with naked eyes (that we suppose to see in experiment i.e DNA extraction)....
The actual role of phenol chloroform isoamyl alcohol in a plasmid DNA extraction is to purify the DNA. The alcohol will act in part as a detergent.
DNA is not soluble in isopropyl alcohol. It will precipitate out when you add this solvent. Once out of solution you can centrifuge it down and collect the pellet of DNA.
For humans, blood is easily accessible. There are standard procedures to safely obtain blood from an individual and DNA can be extracted from the white blood cells. However, DNA can also be obtained from hair and salivary swabs but these are not considered tissues.
All cells have DNA in them. If you take cells from your mouth and finger they would have the same genetic code.
