BIOl 3001 EXAM QUESTIONS WITH
COMPLETE ANSWERS!!
, Electrophoresis - ANSWER__________ is a series of techniques by which
biomolecules can be separated based on size, length and/or shape.
Electrophoresis Learning System - ANSWERYou will be using a new computer program
this week called ELS which stands for ________ ________ _______.
Length - ANSWERThe fragments of DNA we will be examining this week in lab will be
separated based on fragment _____________.
Denature the DNA into single strands. - ANSWERWhat is the primary purpose of
heating your samples prior to loading them to the gel?
autoradiography - ANSWERThe 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 - ANSWERThe DNA fragments used in this will exhibit a very simple mode of
inheritance, which is Simple Mendelian.
1;2 - ANSWERBecause 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 - ANSWERThe 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
