Which of the following is NOT a use of DNA fingerprinting?
A
Determining the exact amino acid sequence of a protein in a tissue sample
B
Identifying human remains after a disaster using reference samples
C
Establishing biological relatedness in paternity or kinship testing
D
Matching biological evidence to a suspect in forensic investigations
Verified step by step guidance1
Understand what DNA fingerprinting is: a technique used to identify individuals based on unique patterns in their DNA sequences.
Review the common applications of DNA fingerprinting, such as identifying human remains, establishing biological relationships, and matching evidence in forensic cases.
Recognize that DNA fingerprinting analyzes DNA patterns but does not provide information about protein sequences or amino acid order.
Evaluate each option by asking whether it involves analyzing DNA patterns or requires direct protein sequencing.
Conclude that determining the exact amino acid sequence of a protein is not a use of DNA fingerprinting, as this requires protein sequencing techniques, not DNA pattern analysis.
