Ons, Codons, Omes Flashcards
(8 cards)
1
Q
What are introns?
A
- sections of DNA, don’t code for polypeptides, found only in eukaryotic DNA
2
Q
What are exons?
A
- Sequence of DNA, codes for amino acids
3
Q
What’s a codon and the two types?
A
Codon - three bases on mRNA that code for specific amino acid
- Start codon
- Stop codon
4
Q
Start codon?
A
- Three bases at the start of every gene that initiates translation
5
Q
Stop codon?
A
- three bases at the end of every gene that cause ribosomes to detach and therefore stop translation
6
Q
Genome?
A
- organisms complete set of genes in a cell
7
Q
Proteome?
A
- Full range of proteins that a cell is able to produce
8
Q
Do genomes and proteomes change?
A
- The genome should never change, but the proteome of the cell is constantly changing, depending on which proteins are currently needed
