BIOL 3001 QUIZ QUESTIONS 100%
ANSWERED RATED A+
, ____________ is a series of techniques by which biomolecules can be separated based
on size, length, and/or shape - ANSWERelectrophoresis
You will be using a new computer program this week called ELS which stands for
Electrophoresis Learning System - ANSWERTrue
When using the ELS program, the samples should be heated for a minimum of
__________ minutes - ANSWER5
The fragments of DNA we will be examining this week in lab will be separated based on
fragment _________ - ANSWERlength
why it is so important to control the time of gel electrophoresis. what might happen if the
gel runs too short of a time versus too long of a time. - ANSWER1. not enough
resolution/separation of the band fragments if the gel runs too short making it difficult to
interpret and 2. loss of data if bands are run off the end of the gel
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 ___________ - ANSWERautoradiography
The DNA fragments used in this lab will exhibit a very simple mode of inheritance, which
is ___________ - ANSWERco-dominance
When using microsatellites as genetic markers, as we do in this lab exercise, it is easy
to identify heterozygotes because they all show 2 bands. True or False? -
ANSWERTrue
Genotyping also provides us with another critical lesson, namely that __________ -
ANSWERuncertainly exists in all scientific studies
The scientific name (genus species) for the fruit fly (red-eyed pomace fly) is? -
ANSWERDrosophila melanogaster
How many PAIRS of chromosomes doe fruit flies have? - ANSWER4
For the Lygaeus Mode of Sex-determination, list the chromosome assignment for each
gender - ANSWERFemale: XX
Male: XY
Why are the Parentals of most crosses homozygous (1 dominant and 1 recessive)? -
ANSWERall offspring in first Filial (F1) will be heterozygous
