DNA Test

What is the primer that is required to initiate the synthesis of a new DNA strand?

• RNA

• DNA

• Protein

• Ligase

Which enzyme catalyzes the elongation of a DNA strand in the 5' -> 3' direction?

• Primase

• Ligase

• Helicase

• DNA Polymerase

A frameshift mutation could result from

• A base deletion only

• A base substitution only

• Deletion or insertion

what does Adenine go with

• thymine

• cytosine

• guanine

Data points are used to determine which base pairs match within the gel. If the pairs match, there is a high likelihood that both strands belong to the same individual.

• Analyze DNA

• Gel Electrophoresis

• Use Restriction Enzymes

Why are restriction enzymes used when making a DNA fingerprint using STRs?

• They are used to determine the size and shape of DNA fragments.

• They are used in order to allow us to determine if a specific family or family member is related to the crime based on their DNA fragments.

• STR bands are units of bases that are typically two to five bases long and repeat multiple times. Restriction enzymes cut these bands since they match the enzyme, making them easily recognisable.

Which part(s) of a hair can be analyzed for DNA?

• root

• cuticle

• medulla

• cortex

This is the last step of PCR and it requires the temperature to increase to 72C for one minute. Here, complementary strands will be produced from the corresponding base pairs, reforming the DNA into two new strands.

• Elongation by DNA Polymerase

• Primer Annealing

• Denaturation

DNA can be used for ...

• determining paternity

• identifying human remains

• identifying a suspect

• All of these
