The parents of a new baby believe they brought the wrong child home from the hospital. Gel electrophoresis was performed using DNA samples from the parents and the child. A section of the gel
electrophoresis results is shown below. Which conclusion is valid based on the gel electrophoresis results?
They have the correct child, because her genetic information is identical to that of the father.
They have the wrong child, because her genetic information does not match that of either parent.
They have the correct child, because her genetic information came from both parents.
They have the wrong child, because her genetic information matches only that of the mother.
In preparation for an electrophoresis procedure, enzymes are added to DNA in order to
convert the DNA into gel
cut the DNA into fragments
change the color of the DNA
produce longer sections of DNA
A student performed a gel electrophoresis experiment. The results are represented in the diagram
below. Compared to the fragments at the top of the gel, the fragments at the lower end are
larger, and move slower
larger, and move faster
smaller, and move faster
smaller, and move slower
Which is NOT true regarding gel electrophoresis?
Agarose gel acts as a molecular seive, separating DNA fragments based on size
Larger DNA fragments will maigrate farther than small DNA fragments
By passing an electrical current throught he gel, DNA fragments move toward the positive end
Fragments of known size are used to measure the size of the DNA samples
