Here's why:
* Ribosomes are the protein synthesis factories of the cell. They are composed of ribosomal RNA (rRNA) and proteins.
* Messenger RNA (mRNA) carries the genetic code from the DNA in the nucleus to the ribosomes in the cytoplasm.
* Codons are three-nucleotide sequences on the mRNA that specify which amino acid should be added to the growing polypeptide chain.
* tRNA (transfer RNA) molecules act as "adaptors", recognizing specific codons on mRNA and bringing the corresponding amino acid to the ribosome.
The ribosome uses its rRNA and protein components to:
1. Bind to mRNA.
2. Move along the mRNA, reading the codons one at a time.
3. Recruit tRNA molecules with matching anticodons.
4. Facilitate the formation of peptide bonds between amino acids.
This process, known as translation, results in the synthesis of a protein molecule based on the genetic code encoded in the mRNA.
