DNA Profiling

The pattern of bars in a DNA profile shows

• the order of bases in a particular gene

• the presence of different sized fragments

• the presence of dominant or recessive alleles for a trait

• the order of genes along a chromosome

Which model of base pairing is correct?

• A=T and C=G
• A=T=C=G
• A+T and G+C
• A=G and T=C

If base-pairing rules state that Adenine always pairs with Thymine, and Cytosine pairs with Guanine, what would be the complementary strand to ACGGT?

• ACGGT
• TGGCA
• TGCCA
• ACCGT

The computerized database used to store DNA information is: 

• AFIS
• NIBIN
• CODIS
• PDQ

Which suspect is likely guilty?

• Suspect #1
• Suspect #2
• Suspect #3
