Roles in Protein Synthesis:
Transcription: In the cell nucleus, DNA's instructions are transcribed into mRNA. This is like copying a recipe from a cookbook.
mRNA Processing: Before leaving the nucleus, mRNA is modified by adding caps and tails. These modifications help protect the mRNA and guide it to the ribosome.
Translation: In the ribosome, tRNA brings the correct amino acids based on the mRNA code. The ribosome reads the mRNA code and links amino acids together to build a protein chain.
