Briefly describe the process of translation?
- rRNA reads mRNA codon by codon
- rRNA sends a message to the complementary anticodon (tRNA) to truck back to the ribosome the appropriate amino acid.
- tRNA travels to the ribosome/mRNA complex bringing it’s amino acids.
- Amino acids hook together forming an amino acid chain or protein.
- When the ribosome finishes reading the mRNA it detaches and goes off to find a new mRNA.
- tRNA’s go off into the cytoplasm to find another amino acid.
- The mRNA may bond up with another ribosome and repeat the process.
