ASU BIO 340 Exam Questions with
Verified Answers
What is transcription? - ✔✔DNA to RNA
What is translation? - ✔✔RNA to protein
To serve as genetic material, molecule must be able to: - ✔✔replicate, store information,
express information, allow variation by mutation
Three major types of macromolecules in genetics: - ✔✔Deoxyribonucleic acid, ribonucleic acid,
proteins and enzymes
deoxyribonucleic acid (DNA) - ✔✔storage molecules for genetic instructions to carry out
metabolism and reproduction
ribonucleic acid (RNA) - ✔✔expresses the information in DNA
proteins and enzymes - ✔✔build cellular structures and do cellular work
Antigen - ✔✔Is a protein or a molecule that your body responds to/ creates an immune
response that the body reacts to
What did Fredrick Griffith identify in pneumococcus? - ✔✔Rough and smooth phenotype
The Rough phenotype was - ✔✔Non pathogenic in animals
,The smooth phenotype was - ✔✔Fatal in animals
How could the smooth phenotype convert to the rough phenotype? - ✔✔A single gene
mutation of the same antigenic type
What are the four antigenic types? - ✔✔I, II, III, and IV
In Fredrick's mice experiment, what happened to the mice when it was Injected with the
smooth phenotype? - ✔✔It died
In Fredrick's mice experiment, what happened when the mice was inject with the heated
smooth phenotype? - ✔✔It lived
In Fredrick's mice experiment, what happened to the mice when it was injected with the rough
phenotype? - ✔✔It lived
In Fredrick's mice experiment, what happened to the mice when it was in heated with the
combination of the heated smooth phenotype and the regular rough phenotype? - ✔✔It died
What is the central dogma? - ✔✔DNA -> RNA -> Protein
from one generation to the next... - ✔✔1.DNA stores genetic information
2. Information is duplicated by replication and is passed onto the next generation
DNA and RNA are both - ✔✔polymers of nucleotides
Nucleotides are composed of - ✔✔1. Phosphate group
2. Sugar (deoxyribose or ribose)
, 3. Nitrogenous base (purines and pyrimidines)
RNA nucleotide has - ✔✔1. Phosphate group
2. Ribose sugar
3. Nitrogenous base (purines and pyrimidines)
DNA nucleotide has - ✔✔1. Phosphate group
2. Deoxyribose sugar
3. Nitrogenous base (purines and pyrimidines)
What does deoxy mean? - ✔✔without oxygen
What are purines? - ✔✔Adenine (A) and Guanine (G)
What are pyrimidines? - ✔✔cytosine, thymine, uracil
What is a nucleoside? - ✔✔1. Nitrogenous base
2. Penrose sugar
3. Purine or pyrimidine base
4. Ribose or deoxyribose sugar
Ribonucleosides have.. - ✔✔adenosine, guanosine, uridine, cytidine
triphosphates do what? - ✔✔Serve as a precursor molecule during nucleic acid synthesis
Types of triphosphates? - ✔✔ATP and GTP (both of them use a large amount of energy in
adding/removing a terminal phosphate group)
