Electrophoresis ANSW ✔✔ __________ is a series of techniques by which
biomolecules can be separated based on size, length and/or shape.
Electrophoresis Learning System ANSW ✔✔ You will be using a new computer
program this week called ELS which stands for ________ ________ _______.
Length ANSW ✔✔ The fragments of DNA we will be examining this week in
lab will be separated based on fragment _____________.
Denature the DNA into single strands. ANSW ✔✔ What is the primary
purpose of heating your samples prior to loading them to the gel?
autoradiography ANSW ✔✔ The final step in the ELS program is to "develop"
your gel so that the DNA fragments become visible. This technique uses a small
amount of radioactive phosphorus and is called ___________.
false ANSW ✔✔ The DNA fragments used in this will exhibit a very simple
mode of inheritance, which is Simple Mendelian.
1;2 ANSW ✔✔ Because of the simple mode of inheritance it will be very easy
to distinguish homozygotes from heterozygotes during this lab exercise.
Homozygotes will all show _______ band(s) and heterozygotes will all show
__________ band(s).
uncertainly exists in all scientific studies ANSW ✔✔ The Genotyping that we
will be using in this exercise provides us with an example of how science can
, help solve a problem. Genotyping also provides us with another critical lesson,
namely that ____________________.
Drosophila melanogaster ANSW ✔✔ The scientific (genus species) name for
the fruitfly (or red-eyed pomace fly) is?
8 ANSW ✔✔ Fruitflies have a total of _______ chromosomes.
XX, XY ANSW ✔✔ Fruit flies exhibit the Lygaeus Mode of Sex-determination.
For each gender below, give the correct chromosome assignment.
FEMALE ______
MALE ______
homozygous / homozygous ANSW ✔✔ For the Medelian option, the Fly
Colony program is designed so that the F1 progeny are all heterozygotes. This
result simulates exactly what happens if we were crossing real flies and occurs
because one Parent is _________ dominant while the other is selected to be
_________ recessive.
93 ANSW ✔✔ A total of 372 offspring are produced. Some are red and some
are blue. Given the cross that you made, you expected a ratio of 3 red : 1 blue.
How many blue offspring did you expect from the 372 progeny? (please enter
your answer numerically in whole numbers, no decimals)
106 ANSW ✔✔ A total of 424 offspring are produced. Some are red and some
are blue. Given the cross that you made, you expected a ratio of 3 red : 1 blue.
How many blue offspring did you expect from the 424 progeny? (please enter
your answer numerically in whole numbers, no decimals)
