What we have here is an MCQ quiz on the molecular biology of DNA replication! The DNA of a human can copy itself, which is one reason why people of the same bloodline can be identified using a DNA test. Do you know the processes through which the DNA actually duplicates itself and the results thereafter? This quiz will serve as a way to refresh your memory.

- 2.When double-stranded DNA is heated to 94-95ºC, it becomes single-stranded due to the hydrogen bonds breaking. This process is called _______.
- 3.When single-stranded DNA is cooled to below 60ºC, it becomes double stranded due specific base pairing. This process is called _______.
- 4.In Meselson and Stahl's experiment, _______ generation(s) after cells were transferred from heavy-nitrogen medium to light nitrogen medium, all of the DNA was of hybrid density. (Type in a number.)(I believe we didn't cover this one this year, 2010).

Sample QuestionWhat are the four nitrogen bases for DNA?
Transcription is the first step of gene expression, where the messenger RNA is decoded in a ribosome to produce polypeptide which later folds into an active protein and performs its functions in the cell. During this one week, we...
