DNA Analysis

Any process that determines the order of nucleotides (A,T,C,G) in a DNA sample is called this:

Why is Next Generation Sequencing used?

• When the sample is too long for Sanger sequencing

• When the sample has been contaminated

• When there is no "known" to compare the sample to

• When the species of origin of the DNA is not known

Which DNA sample was matches the DNA found at the crime scene?

• Sample "S1"

• Sample "S2"

• Sample "S3"

The maximum length of DNA that Sanger sequencing can determine is approximately how many base pairs long?

• Eight

• Eight hundred

• Eight hundred thousand

• Eight hundred million

Which strands travel the farthest in gel electrophoresis?

• Strands with more pyrines

• Strands with more pyrimidines

• Longer strands

• Shorter strands

Which man could be the father of Joy's baby?

• Man 1

• Man 2

"STR" stands for...

Gel electrophoresis looks for differences in:

• The STRs in a person's non-coding DNA

• The length of a person's coding DNA

• The nucleotide sequence in a person's genome

• The number of chromosomes in a person's genome

What is the purpose of the "ladder" used in gel electrophoresis?

• To test the strength of the electric field

• To establish the distance "A", "T", "G", and "C" will move

• To establish the distance known DNA lengths moved

• To determine the molecular weight of DNA molecules

The acronym for the federal forensic DNA database is:
