Anticodons, which are found on (a) (type of RNA), are used to match the codon of mRNA to ensure the proper amino acid is transferred over.
A codon is found on ____, and is a 3 nitrogen base letter combination that codes for a specific amino acid.
mRNA
rRNA
tRNA
DNA
The image shows translation. What is tRNA transferring to the ribosome?
amino acids
mRNA
codons
energy
A (a) codon means it is the end of translation, so the mRNA will leave because the polypeptide (protein) is done being made.
A (a) codon tells the ribosome to begin protein synthesis.
If you are given tRNA antiocodon of ( G A U ), what would the DNA sequence of that be? (HINT: Work backwords, look at the image for an example of what to do).
