MCB 317 Exam Questions with CORRECT
Answers
All the cells in any given colony on your plate are genetically identical.
True
The cells in one colony are genetically identical to the cells in each of the other colonies
False. WHY?
Which of the following organisms are amenable to classic genetic analysis?
Yes: Drosophila melanogaster ("fruit flies"), yeast, C. elegant (nematode, "worms")
No: Humans
What technique allows you to make a duplicate copy of a plate containing may yeast
colonies?
Replica plating
Based on our discussion in lecture, expression of the eyeless gene in Drosophila is:
both necessary and sufficient to initiate the process of eye development
You clone the wild-type version of a gene and engineer it to be ectopically expressed. Based
on our discussion in lecture, is your newly constructed gene more accurately described as
a:
Gain of Function allele
,Genetics can be used to refer either to a scientific discipline or to a set of technologies that
can be used to study biological processes.
True
Based on our discussion in lecture which of the following characteristics are governed in
part, or in whole, by genetics?
cell specialization, intellectual potential, body plan, development, some behaviors, morphology
Which of the following processes are involved in the expression of genetic information?
Translation and Transcription
Which of the following processes are involved in the maintenance of genetic information?
Repair, Replication, Segregation
Which of the following processes are involved in the generation of genetic diversity?
Recombination
As described in lecture, Molecular Genetics/Recombinant DNA technology bridges
Biochemistry and Classical Genetics.
True
The simultaneous study of all proteins in an organism is refered to as:
proteomics
As described in lecture, the "unity of biology" is a reflection of
evolutionary relatedness of organisms
, As described in class, which of the following best describes the goal of the procedure
"replica plating"?
To identify mutants defective in growth control in yeast
As discussed in lecture, it is often easier to identify several mutants with a particular
phenotype than it is to figure out which of several mutants is likely the most important one
to study.
True
Which term is most accurately describes a pure breeding strain?
homozygous
Abbott Napp posed the question "What is the role of chance in heredity?" The answers
below are Mendel's first law, divided into pieces. Which of the pieces is most closely related
to Abbott Napps question?
And then unite at random
Which of the following were important elements of Mendel's experimental design?
- Controlled matings and reciprocal crosses
- Choice of traits that had clear-cut alternate forms (antagonistic forms)
- The use of pure breeding lines
-Choice of experimental organism
