Common mistakes
Confusing DNA sequencing with genetic fingerprinting
Students often confuse the two techniques, thinking they serve the same purpose.
Fix itDNA sequencing determines the exact order of nucleotides, while genetic fingerprinting focuses on identifying unique patterns of DNA fragments.
Confusing DNA fingerprinting with DNA sequencing
Students often think DNA fingerprinting provides the exact sequence of nucleotides.
Fix itDNA fingerprinting analyzes specific regions of DNA for variability, while sequencing determines the exact order of nucleotides.
Confusing genetic fingerprinting with DNA sequencing
Students often think genetic fingerprinting provides the complete DNA sequence.
Fix itGenetic fingerprinting focuses on specific regions of DNA for identification, not the entire sequence.
Misinterpreting DNA fingerprint similarity as identity
Assuming that two DNA fingerprints that share some bands are identical individuals.
Fix itExplain that shared bands indicate similarity but not identity; full pattern comparison is required to confirm identity.
