True or false: when loading samples of your DNA into the micropipette it is not necessary to change the tip after you load each sample.
False
300
What are biometrics?
The measurement and analysis of unique physical or behavioral characteristics (as fingerprint or voice patterns) especially as a means of verifying personal identity.
300
When DNA is put into the gel what end does it start at (the positive end or the negative end)?
It carries genetic instruction, including those that make all of the proteins in our bodies.
300
What is used to “digest” a DNA sample?
Restriction enzymes
400
What is Gel electrophoresis?
The separation of nucleic acids or proteins, on the basis of their size and electrical charge, by measuring their rate of movement through an electrical field in a gel.
400
When conducting a gel electrophoresis lab where do you put the DNA samples in the grose gel once the comb is removed?
wells
400
Which of these is not a current form of biometrics?
True or False: Our DNA can determine whether or not we may get certain diseases or illnesses in the future?
True
400
How are DNA samples compared to each other?
By size and by charge
500
What are Restriction fragment length polymorphisms?
Differences in DNA sequence on homologous chromosomes that can result in different patterns of restriction fragment lengths (DNA segments resulting from treatment with restriction enzymes).
500
What cuts the Restriction Fragment Length Polymorphisms into their segments?
Restriction Enzymes

How can the oils from your skin affect the readings on a fingerprint scanner?
some fingerprint scanners are sensitive to moisture which can lessen the accuracy of this method working
500
True or false: DNA does not carries the instructions that make up the proteins in our bodies?
False
500
True or False: Negatively charged DNA samples move towards the positive end of the gel in gel electrophoresis?
