Question
A full DNA profile may be located in all but which of the following?Question 11Select one:a.hair pulled out by forceb.hair that falls out naturallyc.tooth pulpd.semene.saliva
Solution
The correct answer is b. Hair that falls out naturally.
Here's why:
a. Hair pulled out by force: This type of hair often contains the root, which has cells and therefore DNA.
b. Hair that falls out naturally: This type of hair usually lacks the root, which is where the DNA is located. Therefore, it's less likely to provide a full DNA profile.
c. Tooth pulp: This contains cells, and therefore DNA can be extracted from it.
d. Semen: This contains sperm cells, which contain DNA.
e. Saliva: This contains cells shed from the mouth and throat, which contain DNA.
