100
he first to build an accurate model of DNA and to describe it explicitly in a publication
Who is Watson and Crick
100
a set of three nucleotides
What is codon
100
This nucleotide is not incorporated into the structure of the DNA helix.
What is uricil
100
The product of this item can inactivate a gene.
What is a regulator gene
100
The anticodon AAA pairs with this codon.
What is UUU
200
discovered that DNA-digesting enzymes prevented bacterial transformation
Who is Avery
200
guided and catalyzed by RNA polymerases
What is transcription
200
Two hydrogen bonds connect guanine to __________ in the DNA molecule.
What is cytosine
200
When the repressor is inactivated, RNA polymerase can bind to this item and allow transcription to occur.
What is a promoter
200
A DNA codon of ATT is complementary to this RNA codon.
What is UAA
300
first to discover DNA and isolate it from fish sperm
Who is Miescher
300
RNA-directed synthesis of polypeptide chains
What is translation
300
This nucleotide is a double-ring molecule.
What is guanine/adenine/purine?
300
A repressor protein can shut down transcription by binding to this item.
What is an operator
300
This codon codes for an amino acid and indicates the beginning of a coding region.
What is AUG (start codon)
400
provided two important clues to the structure of DNA; one clue is that A = T and the other is that C = G
Who is Chargaff
400
binds to small subunit platform of a ribosome
What is messenger RNA
400
Erwin Chargaff's data indicates that within a species the amount of adenine is always equal to the amount of this.
What is thymine
400
This item contains regulator, promoter, and operator regions.
What is an operon
400
This codon terminates a coding region.
What is a stop codon
500
the first to demonstrate, through the use of radioactive isotopes, that DNA, not protein, is the genetic material
Who is Hershey and Chase
500
polypeptide chain elongation proceeds independently at each body in this cluster
What is polysome
500
If one chain of a DNA molecule has a purine at a given position, this complements it on the other chain.
What is pyramadine
500
This item codes for the production of a repressor.
What is a regulator gene
500
A single mutation involving the second letter of codon AUA could convert it to this codon.
What is AAA, AGA, ACA
