BSC 101 Exam 2
Describe DNA structure - ✔✔DNA forms a double stranded helix and adenine pairs with
thymine, and cytosine pairs with guanine
What pair forms hydrogen bonds and how many - ✔✔thymine/adenine form 2 bonds
guanine/cytosine form 3 bonds
Explain "the central dogma" - ✔✔DNA turning into RNA turning into Protein
What is transcription - ✔✔Copying of DNA code to RNA, one nucleotide at a time so it is
complementary to the DNA
What is translation - ✔✔RNA gets translated into protein
Universal genetic code regarding evolutionary theory and biotechnology - ✔✔Universal = all
living organisms ever discovered use the same code - this shows every organisms use the exact
same genetic code - (more evidence all life shares a common evolutionary ancestor) =
evolutionary theory
Biotechnology = if the genes didn't share the same genetic code you can't take one gene and
place it in another - it limits the use
Process of Gene expression - ✔✔Different cells in different genes can express differently - genes
can be turned on and off and if it is off proteins can't be produced
The process of turning on a gene to produce RNA and protein
Just because a cell has a particular gene does not mean it is transcribed into RNA and then
transcribed into protein
For a cell to function properly they correct proteins must be synthesized at the proper time
Each cell only expresses those genes that make it function as that particular cell type that it is
What are the biotech tools - ✔✔- DNA Extraction
- Gel Electrophoresis
- PCR
- Molecular cloning
- Reproductive cloning
What is the purpose of DNA Extrac
