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.
Questions and Answers
The first DNA polymerase was discovered by _______.
Watson and Crick
When double-stranded DNA is heated to 94-95ºC, it becomes single-stranded due to the hydrogen bonds breaking. This process is called _______.
When single-stranded DNA is cooled to below 60ºC, it becomes double stranded due specific base pairing. This process is called _______.
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).
In Meselson and Stahl's experiment, _______ generation(s) after cells were transferred from heavy-nitrogen medium to light nitrogen medium, half of the DNA was of hybrid density. (Type in a number.)(I believe we didn't cover this one this year, 2010).
In 1958, Meselson and Stahl proved that DNA replication was _______.
