30s - Q2Deoxyribonucleic Acid (DNA)A complex molecule containing the genetic information that makes up the chromosomes.
A complex molecule containing the nutrients that makes up the cells.
A complex molecule containing the water required for homeostasis.
A complex molecule that provides fuel for cellular functions.
30s - Q3Polymerase Chain Reaction (PCR)a technique that allows molecular biologists to make many copies of a particular gene.
a technique that allows molecular biologists to create a DNA fingerprint to identify suspects.
a technique that allows molecular biologists to create new life from old cells.
a technique that allows molecular biologists to synthesize proteins.

30s - Q7
Differences in DNA sequence on homologous chromosomes that can result in different patterns of restriction fragment lengths
Restriction Fragment Length Polymorphisms (RFLPs)
Polymorphism Restriction Fragment Length (PRFLs)
Fragment Length Restriction Polymorphism (FLRPs)

30s - Q8
Pairs of letters on the opposite sides of each other on the DNA ladder
Ribose and Deoxyribose (rad)
Phosphate and sugar (pas)
Base Pairs (bps)

30s - Q9
The technique/procedure used to separate DNA fragments according to their size/charge
Gel Electrophoresis
Gel Electrolysis
Electrophoresis Tank
Electrolytic gel
30s - Q10What is an electrophoresis 'run'?The process of electrophoresis as the current runs through the gel.
The process of making the agarose gel
The preparation of DNA using restriction enzymes
The description of the gel from the flask to the tray
30s - Q11
