Translation: RNA to Protein

Science, Grade 6


Table Of Contents: Translation: RNA to Protein

1. What Is Translation?
The process of converting the coded information on the messenger RNA to a protein is called translation.
2. Messenger RNA Attaches to a Ribosome
The mRNA travels through a nuclear pore to the cytoplasm and attaches to a ribosome. The ribosome moves along the mRNA strand, translating the code.
3. Messenger RNA Codons
Three sequential mRNA bases form a triplet code for a particular amino acid. Each triplet is called a codon.
4. Transfer RNA
Another type of RNA called transfer RNA (tRNA) carries specific amino acids.
5. Anticodons
Every tRNA has an anticodon region that is complementary to a specific codon on the mRNA.
6. Amino Acid Chain
Each time a tRNA anticodon and codon pair, an amino acid is added to a chain that eventually forms a specific protein.
7. Transfer RNA Molecules Work Together
Many tRNA molecules and ribosomes work together at the same time along one strand mRNA.
