1
Q
Codon
A
a sequence of three nucleotides which together form a unit of genetic code in a DNA or RNA molecule.
2
Q
anticodon
A
a sequence of three nucleotides forming a unit of genetic code in a transfer RNA molecule, corresponding to a complementary codon in messenger RNA.
3
Q
translation
A
the process where a cell uses the information encoded in messenger RNA (mRNA) to synthesize a protein by linking amino acids together,
4
Q
start codon
A
AUG
5

A
UAA
UAG
UGA
6
Q
role of mRNA
A
Contains message/code for amino acid sequence
7
Q
role of tRNA
A
transfers amino acids, contains anti codons that pair w mRNA codons to put amino acids in the correct order
8
Q
role of rRNA
A
facilitate matching of mRNA and tRNA
