Gel Electrophoresis

The DNA analysis technique shown in the diagram directly results in the

• separating DNA fragments on the basis of size

• Synthesizing large fragments of DNA

• Producing genetically engineered DNA molecules

• Removing the larger DNA fragment from the samples

The Laboratory Technique shown is known as

• DNA replication

• Genetic recombination

• Gel Electrophoresis

• Protein Synthesis

Electrophoresis is a method of

• Changing the genetic code of an organism

• Separating colored compounds on a strip of paper

• Separating DNA fragments

• Indicating the presence of starch

The four wells represented in the diagram were each injected with fragments that were prepared from DNA samples using identical techniques

The arrow in the diagram represents the direction of the movement of the DNA fragments. What is responsible for the movement of the DNA of the DNA in this process

• Electricity

• RNA

• water

• alcohol

Identify the specific substance used to cut the DNA in this procedure

• chromosomes

• restriction enzymes

• monosaccharide

• lipids

Where are the smallest fragments of DNA located on the gel in the illustration

• near the wells

• at the opposite end of the wells

• in the middle

• to the left

The diagram represents the results of the procedure known as

• cloning

• chromatography

• gel electrophoresis

• protein sequencing
