During translation, which takes place in the cytoplasm, mRNA, tRNA, and rRNA interact with each other, and amino acids are added according to the mRNA codon sequence. Anticodons: UAC, UUC, CCG, GUU, GCU, GAA, AUA. Protein Met-Lys-Gly-Gln-Arg-Leu-Tyr.
What is translation?
The translation is the stage of protein synthesis in which mRNA, rRNA, and tRNA interact to grow the molecule.
The ribosome is in charge of reading mRNA from its 5' extreme to 3' extreme. Meanwhile, tRNA associates with the ribosome to build the polypeptidic chain. Molecule growing occurs according to the mRNA codon sequence.
A codon is a short sequence of three nucleotides that store the genetic information for the aminoacids' assembly.
Each tRNA has two important sites. One of them couples with the codon of the mRNA molecule, named anticodon. The other site couples with an amino acid.
When the new amino acid binds to the growing peptidic chain, the tRNA molecule leaves the ribosome, leaving a space for the next tRNA.
• The start codon AUG is the most common sequence used by eukaryotic cells and is placed near the 5' extreme of the molecule.
• The stop codons are UAA, UAG, and UGA.
In the exposed example, we just need to couple each mRNA codon with the tRNA anticodons. The way to do it is by pairing the correct bases,
Adenine ⇔ Uracyl
Guanine ⇔ Cytosine
mRNA ⇒ 5' - AUG AAG GGC CAA CGA CUU UAU-3'
tRNA ⇒ UAC UUC CCG GUU GCU GAA AUA
Amino acids ⇒ Met Lys Gly Gln Arg Leu Tyr
The final protein is Met-Lys-Gly-Gln-Arg-Leu-Tyr
