Enzymes
This enzyme unwinds a double helix by breaking hydrogen bonds.
What is helicase
Rosalind Franklin provided evidence for this using X-Ray crystallography.
What is DNA is a double helix.
This complimentary nucleotide binds to Adenine with hydrogen bonds.
RNA nucleotides have this sugar.
What is ribose?
This is the order of amino acids.
What is the primary structure of a protein?
This enzyme stabilizes over-twisted DNA strands by binding to them and allowing bonds to break and reform.
What is gyrase
These scientists published the correct structure of DNA.
Who were Watson and Crick.
We call prokaryotic DNA naked because it is not associated with these.
What are proteins?
These segments of mRNA are expressed.
What are exons?
This kind of bond causes amino acids to automatically form alpha helices and beta pleated sheets.
What is a hydrogen bond.
This enzyme is responsible for unwinding the double helix and creating a strand of RNA that is complimentary to the antisense strand.
What is RNA polymerase?
Who were Meselson and Stahl.
In eukaryotes, a nucleosome is made of DNA wrapped around this protein.
What is a histone?
This RNA nucleotide binds to uracil.
What is adenine?
This term describes what happens when a protein loses its 3D shape.
What is denatured.
This enzyme is responsible for removing RNA primers from the new DNA strand and replacing it with complimentary DNA nucleotides.
DNA polymerase I.
These two techniques is used (along with dideoxynucleotide triphosphates) to figure out the sequence of nucleotides in DNA.
What are PCR and gel electrophoresis.
New nucleotides can only be added to a growing strand in this direction.
What is the 3 prime direction?
This enzyme complex is responsible for removing introns from mRNA.
What is the spliceosome complex?
This level of protein structure is characterized by interacting alpha helices and beta pleated sheets.
What is the tertiary structure?
This enzyme uses the energy from deoxyribo-nucleotide triphosphates (dNTPs) to create phosphodiester bonds on a growing nucleic acid strand.
What is DNA Polymerase III.
These scientists used radioactive sulfur and radioactive phosphorous to prove that DNA is the genetic material.
Who were Hershey and Chase?
This covalent bond links nucleotides of one strand together.
What is a phosphodiester bond?
This RNA strand contains anticodons and amino acids.
What is tRNA?
This distinguishes the tertiary and quarternary levels of protein structure, both of which are stabilized by covalent, ionic, and hydrogen bonds.
What is multiple interacting polypeptides?
