What is DNA?
DNA stands for
What is deoxyribonucleic acid?
DNA is a ____ stranded molecule.
What is double stranded molecule?
How many base pairs are found in DNA?
What is 4?
This is responsible for synthesizing DNA. It adds nucleotides to a DNA chain.
What is DNA polymerase?
The 2 scientists who discovered DNA are:
Who are James Watson and Francis Crick?
DNA is an organic molecule called
What is a nucleic acid?
DNA is made up of __ strands.
What is 2?
Adenine always pairs with
What is thymine?
This is normally found at the replication fork. It provides a 3' end for DNA polymerase to work on.
What is DNA primase?
Most eukaryotic chromosomes are...
What is linear?
The 4 nitrogenous bases are...
What are adenine, thymine, guanine, and cytosine?
Its double helix is always ____
What is antiparallel?
Cytosine always pairs with
What is Guanine?
This is the first replication enzyme on the replication fork. It moves the replication fork forward by unwinding the DNA.
What is DNA helicase?
A ring shaped protein that keeps DNA polymerase of the lagging strand from floating off when it restarts the new Okazaki fragment is called the ____
What is the sliding clamp?
DNA is located ____ of the nucleus.
What is inside the nucleus?
The backbone of DNA has how many components?
What is two?
The bond that holds the base pairings together is
What is a hydrogen bond?
This forms a bond at a single strand break between the 5 prime and 3 prime ends.
What is DNA ligase?
How does DNA polymerase and other proteins know where to begin?
What are specialized proteins that recognize the origin, bind to the site, and open up the DNA.
The name of the 5 carbon sugar in DNA is
What is deoxyribose?
The 2 components of DNA's backbone are:
What are deoxyribose and phosphate?
If one strand of DNA reads ACTGA, the sequence on the other complementary strand reads
What is A-T, C-G, T-A, G-C, A-T
This prevents supercoiling on the replication fork.
What is topoisomerase?
The job of the single stranded binding protein is...
What is coating the separated strands of DNA near the replication fork, keeping them from coming back into a double helix?
