Genetic Code Flashcards
1
Q
What is a gene?
A
A length of DNA that codes for an amino acid sequence
2
Q
What is the triplet code?
A
3 bases code for 1 amino acid (this is called a codon)
3
Q
What properties does the genetic code have?
A
Universal: almost every organism uses the same code
Non-overlapping: each codon codes only for its specific amino acid
Degenerate: more than one codon can code for the same amino acid
4
Q
What is locus?
A
The fixed position of a gene on a chromosome
5
Q
What are the two types of sections of DNA?
A
Intron: non-coding sections of DNA
Extron: coding sections of DNA
