Their bacteriophage experiment proved that DNA was the genetic material.
What are Hershey and Chase known for?
100
This enzyme unzips DNA.
What is helicase?
100
The process of going from DNA->RNA.
What is transcription?
100
Any change in a DNA sequence.
What is a mutation?
200
The pyrimidine bases.
What are cytosine and thymine?
200
The strain of Streptococcus that caused pneumonia.
What is the smooth strain?
200
A statement about DNA replication meaning a copied strand will be 1/2 new and 1/2 old DNA.
What is semi-conservative?
200
The process of going from mRNA->protein.
What is translation?
200
A mutation that is very small and often does not have a phenotypic effect.
What is a gene mutation?
300
The purine bases.
What are Adenine and Guanine?
300
Mixing R cells with this caused mice to die of pneumonia.
What are heat-killed S cells?
300
This is the complimentary strand to a DNA chain that reads
GTCGAGTAC
What is
CAGCTCATG?
300
Corresponding mRNA sequence to the DNA template
AGCATA
What is UCGUAU?
300
A mutation that affects many genes at once, and often has a phenotypic affect.
What is a chromosome mutation?
400
A two-ring structure, one ring has 6 members while the other has five.
What is the structure of a purine?
400
Avery and his colleagues treated samples with this type of protein (whose name ends in -ase) and saw no transformation proving that the DNA molecule was responsible for transformation.
What are enzymes?
400
This enzyme extends the primer to replicate the DNA strand while moving along the template strand adding DNA nucleotides and extending the new DNA strand.
What is DNA polymerase?
400
Protein sequence made from the mRNA
AUG GGC CGA UGG UAA
What is Methionine(start)-Glycine-Arginine-Tryptophan-Stop?
400
This mutation occurs when the copied chromosome does not cross over in the correct location.
What is translocation?
500
Chargaff's rule.
What is A=T, G=C?
500
This isotope can be used to selectively label DNA.
What is radioactive phorphorus?
500
The phase in the cell cycle in which DNA replication takes place.
What is the S phase?
500
A change in DNA causing mRNA to translate into a premature stop codon.
What is a frameshift mutation?
OR
What is a point (substution) mutation?
500
These will target genetic mutations so they can treat deadly diseases.
