A method used to determine if the DNA found at a crime scene belongs to a particular individual is short tandem repeat (STR) . This method employs
A) repeated sequences found at multiple sites in the DNA.
B) copying one particular gene many times.
C) fluorescent labeling of DNA found in the mitochondria.
D) repeated sequences found at one specific site in the DNA.
E) analyzing the repeated segments at the end of chromosomes called telomeres.
Short Tandem Repeat
A sequence in the DNA consisting of multiple copies of a specific short nucleotide sequence.
Fluorescent Labeling
A technique used in biological research to mark molecules in cells or tissues with fluorescent dyes.
Mitochondria
Organelles known as the powerhouses of the cell, where respiration and energy production occur.
