Study Notes

Translation Process

The process of converting RNA to proteins is called translation.
Translation occurs in the ribosomes, where messenger RNA (mRNA) is read, and a specific amino acid sequence is built.

Codon

A codon is a sequence of three nucleotides in mRNA that codes for a specific amino acid or stops protein synthesis.
There are 64 possible codon combinations, and each codon specifies one of the 20 amino acids or a stop signal.

tRNA Function

The function of transfer RNA (tRNA) in translation is to bring amino acids to the ribosomes during protein synthesis.
tRNA molecules have a specific anticodon that binds to a codon on mRNA, allowing the correct amino acid to be incorporated into the growing protein chain.

Stop Codons

Stop codons are codons that signal the termination of protein synthesis.
There are three stop codons: UAA, UAG, and UGA, which do not code for amino acids.
When a stop codon is reached, the ribosome releases the completed protein chain.

Codon Bias

Codon bias refers to the phenomenon where different codons that code for the same amino acid are not used equally in different organisms.
Codon bias is related to the efficiency and accuracy of translation, as well as the availability of tRNAs in the cell.
Understanding codon bias is important for applications such as gene expression and genetic engineering.
