Q

One chromosome of each homologous pair comes from the mother and one comes from the father, they are similar, but not identical. Each carries the same gene in the same order, but the alleles for each trait may not be the same.

Q

What holds the sister chromatids together in your representation? And what is the protein that does this within the cell?

A

Centromere, cohesion the protein

17
Q

In agarose gel in electrophoresis, where do the DNA samples migrate towards through the gel?

A

Positive electrode

18
Q

What causes the the DNA samples to migrate to the positive electrode?

A

Due to their inherent negative charge.

19
Q

What is the rate of migration through the gel caused by?

A

The size of the DNA

20
Q

What size of pieces moves quickly through the gel?

A

Smaller pieces of DNA migrate quickly

21
Q

What did we conclude the genotype for Nancy?

A

Both carriers.
