Criminal Profiling

DNA profiling can be used to solve crimes even if the case is several decades old.

• True

• False

What is the unique pattern of DNA sequences that can be used for identification in forensic science and paternity testing?

• DNA Fingerprint

• Random DNA Sequence

• DNA Sequencer

• DNA Fragments

What are repeating sequences of 2–6 base pairs in DNA that are used in forensic DNA profiling due to their high variability among individuals?

• Short Tandem Repeats (STR)

• Long Tandem Repeats (LTR)

• Small Tandem Repeats (STR)

• Lingering Tandem Repeats (LTR)

What can be determined about the DNA in bands I and II?

• Band I contains a longer DNA sequence than band II.

• The DNA bands have the same DNA sequence

• The DNA bands are the same size

• Band II contains a longer DNA sequence than band I.

sequence of repeating bases in the non-coding regions of DNA that are used in DNA profiling
