[Lec 1] Key Terms: Structure of DNA Flashcards
1
Q
Mendel
A
He was the first to study transmission of traits and showed definitive heritable patterns
2
Q
Griffith
A
He proved that heritable information can withstand heat killing and passed onto other bacteria; used live R-strain and heat killed S-strain to do so
3
Q
Avery, MacLeod, and McCarty
A
They showed that DNase treatment can abolish the ability of heat killed bacteria to transform other bacteria
4
Q
Chase and Hershey
A
They proved that through viral infection, DNA was heritable material first described by Mendel
5
Q
Cytosine
A
Pyrimidine
6
Q
Uracil
A
Pyrimidine, in RNA only
7
Q
Thymine
A
Pyrimidine
8
Q
Adenine
A
Purine
9
Q
Guanine
A
Purine
10
Q
Chargaff’s Rules
A
- total purines=total pyrimidines; 2. base composition varies between species
11
Q
DNA Role #1
A
Storage of genetic material
12
Q
DNA Role #2
A
Replication and inheritance
13
Q
DNA Role #3
A
Expression of the genetic message
