The Scientists
The process that Frederick Griffith discovered from his experiments with mice
What is transformation?
This is the place where DNA replication happens.
What is the nucleus?
DNA needs to be replicated before these processes.
What are mitosis and meiosis?
This scientists established the following rules:
1. A always pairs with T, C always pairs with G
2. There are always an equal number of purines and pyrimidines
3. General composition of DNA varies by species
Who is Chargoff?
DNA replication occurs during this phase of the cell cycle
What is the S phase?
These make up rungs of the DNA ladder.
What are nitrogenous bases?
These two scientists used radioactive isotopes to prove DNA is genetic material
Who are Hershey and Chase?
This term describes the directionality of DNA
What is antiparallel?
These molecules make up the backbone of DNA.
What are phosphate group and sugar group?
Avery used enzymes to break down macromolecules. His experiments resulted in him discovering that transformation could not occur without this macromolecule.
What is DNA?
DNA is read in triplet sequences known as...
What are codons?
Each of the 2 nucleotide chains in DNA contains all the information because they match. This term describes the matching of the DNA strands.
What are complementary strands?
These macromolecules are made of a phosphate group, a sugar group, and a nitrogenous base. They are the building blocks of DNA
What are nucleotides?
These two men created a model of DNA using information discovered from this female scientist's Photo 51 (Must name all 3 scientists)
Who are Watson, Crick, and Franklin?
The bonds between nitrogenous bases
What are Hydrogen bonds?
The result of DNA replication is 2 new strands of DNA. Each new strand consists of a chain of nucleotides from the orginal template strand and a newly synthesized chain of nucleotides. The phrase that describes this process is...
What is Semiconservative Replication?
This are the roles of DNA. (Name 3)
What is storing information, copying information, and gene expression?
