Study Set Content:
codes for an amino acid.
codon
The reading frame of the codons is defined by the
start and stop codons
Start codon
(AUG
Start codon (AUG) - specifies
methionine
Stop codons
UGA, UAA, UAG
The mRNA is positioned in the ribosome through complementary pairing of the (blank) of mRNA with a rRNA
5’-untranslatedregion
: t-RNAs carries an amino acid on the
3’-terminal hydroxyl
t-RNAs carries an amino acid on the 3’-terminal hydroxyl (A) (aminoacyl t-RNA) and the ribosome catalyzes
amide bond formation.
: large assembly of proteins and rRNAs that catalyzes protein and peptide biosynthesis using specific, complementary, anti-parallel pairing interactions between mRNA and the anti-codon loop of specific tRNA’s.
Ribosome:
The three base codon sequence of mRNA are complementary to the loops of the appropriate tRNA
anti-codon
The base pairing between the mRNA and the tRNA positions the tRNAs for amino acid transfer to the
growing peptide chain.
The genetic information which flows from DNA to mRNA will be translated to the universal language called
protein
The genetic information which flows from DNA to mRNA will be translated to the universal language called protein
TRANSLATION
Under translation, the base sequence of mRNA determines the
amino acid sequences in protein
The adaptor in protein synthesis is
transfer RNA.
Code is a
triplet
Genetic code is
universal
A specific codon codes for the same amino acid in
any species
Exception is
AUG
AUG for prokaryotes
N-formyl methionine
