A
- a common structure across all organisms
- structure of dna is linked to it’s function
- stores genetic information
- copy itself to transmit info from one generation to the next
2

Experiments
3

Prokaryote: transcription and translation occur in cytoplasm
Eukaryotes: transcription occurs in nucleus and translation occurs in cytoplasm
4
Q
What is a gene?
A
The unit of heredity affecting one or more traits of an organism; the DNA sequence that corresponds to a specific protein
5
Q
What is gene expression?
A
The production of a functional gene product, such as protein
- gene expression is regulated
6
Q
Difference in RNA and DNA
A
- sugar (dna: deoxyribose rna: ribose)
- nitrogenous base ( dna: thymine rna: uracil) [A pairs with U in rna)
- 5’ end (dna: monophosphate rna: triphosphate)
- size (dna: very large rna: smaller)
- strands (dna: double rna: single)
