, Thermocycling is the process of: Opening and closing the molecule using repeated heating and cooling cycles.
When the percentage of gas to air is low, that gas is False
flammable. However when the percentage is high, the
mixture is too concentrated to ignite.
What is an advantage of GC-MS? It provides the most accurate confirmation of identification.
What are amplicons? Millions of identical copies of the original or target DNA
What determines how much residue of an accelerant How volatile the accelerant is
will be left and for how long?
Accelerant can be collected off debris for analysis by.. 1. Charcoal absorption
2. Direct injection of headspace vapor
The fire tetrahedron is comprised of: Chemical Chain Reaction
Heat
Fuel
Oxygen
The steps in copying DNA are... Obtain a sequence of double-stranded DNA, split into separate strands,
synthesize new complements.
Who is mitochondrial DNA inherited from? Mother
Clandestine drug laboratories: 1. Pose a significant health and safety threat.
2. Are hidden locations that manufacture controlled substances.
3. Are more complicated to process as a crime scene than traditional crime
scenes.
Opiates are classified as stimulants. False -- they are depressants
What is a nucleotide made up of? Phosphoric acid group
Pentose sugar
Base
Match the type of heat production with its Chemical: result of rapid oxidation
characteristics. Mechanical: production of friction
Electrical: product of arcing, shorting, or other electrical malfunction
Compressed gas: increased molecular activity
