DNA Replication DNA Basics DNA Transcription DNA Translation Topic 7 Random
100
What is a semi-conservative process?
This process is used in DNA replication and is carried out by a complex system on enzymes.
100
Who are Hershey and Chase?
These scientists conducted a series of experiments to prove that DNA is the genetic material in a cell.
100
What is initiation of transcription?
This is the first step in DNA Transcription, where DNA strands are seperated.
100
What is translation initiation?
This is the first step of DNA Translation.
100
What are the A, P, and E sites?
These are the three tRNA binding sites on a ribosome.
200
What is DNA Ligase?
This enzyme joins okazaki fragments together with phosphodiester bonds.
200
What is Sulfur (32P)?
This isotope was radio-labelled "proteins" in the Hershey and Chase experiment.
200
What occurs in the 5' to 3' direction?
RNA polymerase moves along the coding sequence, synthesizing RNA in this direction.
200
What is a peptide bond?
This is the bond formed between the amino acids held by the tRNAs in the P and A sites.
200
What is tRNA?
This type of RNA has a T arm and D arm.
300
What is the 5' to 3' direction?
This is the direction in which DNA polymerase adds nucleotides to a polypeptide chain.
300
Who are Rosalind Franklin and Maurice Wilkins?
These two women used x-ray diffraction to explore the structure of DNA.
300
What is tRNA?
This clover-like structure contains four key regions and is essential in transcription.
300
What is the elongation of polypeptides?
This process of DNA translation involves a repeated cycle of events.
300
What is E. Coli?
The type of bacteria used in Hershey and Chase's experiment.
400
What is DNA Gyrase?
This enzyme comes before helicase in DNA replication.
400
What is a supernatant?
This is where radioactivity was found in the Hershey and Chase experiment using the 32S isotope.
400
What is the rough ER?
This is the region where ribosomes can be found in eukaryotes.
400
What is a stop codon?
When this is reached, translation stops.
400
Who are Watson and Crick?
These two men took credit for Rosalind Franklin's DNA discoveries.
500
What is the leading strand?
This strand can copy continuously, as it moves towards the replication fork.
500
What is a helix?
The shape Rosalind Franklin discovered DNA was in her experiments.
500
What is tRNA activation?
This process illustrates the enzyme-substrate specificity and the role of phosphorylation.
500
What is the P site?
The tRNA detaches from this sight during translation termination.
500
What are phosphates?
These form the outer backbone of DNA.
