Lab 7 Microbial Genetics & Genetic Engineering BIO250L”
Student Name: Jennifer Baeza
Access Code (located on the underside of the lid of your lab kit): ACOF5124A
Pre-Lab Questions
1. Which DNA nitrogenous bases pair with each other? Which bases are purines, and which
are pyrimidines?
Adenine, Guaine AG both being purines. Cytosine with thyme at are pyrimidines.
2. How is DNA information used to make proteins? What are the steps of this process?
used to make proteins through transcription and translation. 1st step, when the enzymes
from the DNA molecules are transcribed into ,mRNA with help from the RNA polymease.
2nd the mRNA reaches the ribosome 3rd tRNA and translated into amino acids that block
the proteins.
3. Give an example of a scenario in which you would perform PCR vs a scenario in which you
would use recombinant DNA technology.
determining the source of an illness and could also be used to get DNA from blood samples , for
example using human growth hormones.
4. What occurs during each of the three steps involved in the PCR cycle? How has the use of
PCR changed biotechnology?
Denaturing, annealing, and elongation. Polymerase chain reaction is a method used in
molecular biology to make millions of physical copies of a specific DNA sequence .
5. How could you take a protein with a known sequence of amino acids
and use it to create an artificial gene?
