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.

Has there been air samples taken from space?
There have not been any air samples taken from space because there is no air in space. Space is vast and there are always particles (usually hydrogen and helium) floating around. However, there is so few particles relative to the vastness of space, that taking samples of the "air" wouldn't accomplish much.
What is the Difference between attribute and variable sampling?
The main difference in taking the samples is that for a variable sample, measurements of a characteristic of interest are taken, and for an attribute sample, one counts the number of units having or not having specific properties (mostly good/bad or number of flaws). Generally, attribute samples are much larger than variable samples and to be useful, need to be very large, when the proportion of bad units (or flaws) is very small.
