History of DNA
These scientists are responsible for discovering that the double helix structure of DNA dictates how it is replicated.
Who are James Watson and Francis Crick?
This is the sugar that is present in a DNA nucleotide.
What is Deoxyribose?
These enzymes help to separate strands of DNA.
What are helicases?
This enzyme catalyzes the formation of RNA on a DNA template.
What is RNA Polymerase?
These are chains of amino acids linked by peptide bonds.
What are polypeptides?
This scientist discovered the pattern of DNA base pairing.
Who is Erwin Chargaff?
This connects the sugar molecules in a strand of DNA or RNA.
What is the phosphate group?
During Step 2 of DNA Replication, this enzyme adds complementary nucleotides to each of the original DNA strands.
What is DNA Polymerase?
This is a specific nucleotide sequence of DNA where RNA Polymerase binds and initiates transcription.
What is a promoter?
This is a three-nucleotide on the RNA that is complementary to the sequence of a codon in mRNA.
What is an anticodon?
This scientist took photographs of DNA crystals and is famed for her work with Erwin Chargaff.
Who is Rosalind Franklin?
These match up to each other to form the double-helix shape of DNA.
What are the Nitrogenous bases?
This is the Y-shaped region that results when two strands of DNA separate.
What is a replication fork?
This is a specific sequence of nucleotides that marks the end of a gene.
What is a termination signal?
This is where the process of translation takes place.
What is a ribosome?
This scientist discovered the biological process of genetic transformation.
Who is Frederick Griffith?
This base matches with Adenine, in DNA exclusively.
What is Adenine?
This is the type of replication used in DNA due to its shape and the way its strands are copied.
What is semi-conservative replication?
This is the term for the rules that relate how a sequence of nitrogenous bases in nucleotides corresponds to a particular amino acid.
What is the genetic code?
This word means "complete genetic content."
What is "genome?"
These scientists concluded that DNA is the hereditary molecule in viruses.
Who are Martha Chase and Alfred Hershey?
This matches with Cytosine in both DNA and RNA.
What is Guanine?
This occurs when there is a change in the nucleotide sequence of a DNA molecule.
What is a mutation?
This is a three-nucleotide sequence in mRNA that encodes an amino acid or signifies a start or stop signal.
What is a codon?
This new field of research uses computers to study and compare different DNA sequences.
What is bioinformatics?
