What we have here is a trivia quiz on molecular biology of DNA replication! The DNA of a human can copy itself and this is one of the reasons 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 there after? This quiz will serve as a way to refresh your memory.
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 _______.
DNA polymerase adds a nucleotide to the ___'-OH (hydroxyl) of a primer DNA molecule. (Type in a number)
The main replication polymerase of E. coli is DNA polymerase ____. (We didn't cover this one this year, 2010).
The enzyme that breaks the hydrogen bonds at the replication fork is called _______.
The protein that binds to single-stranded DNA to keep it from kinking up is abbreviated with the three letters ______.
The short RNA molecule made at the beginning of an Okazaki fragment is called an RNA _______.
Okazaki fragments are needed for replication on the ______ strand.
A reverse transcriptase that is involved in replication of the tips of eukaryotic chromosomes is the enzyme _______.
The end of a eukaryotic chromosome is called the _______.
