• 📜 Job: Carries the 'blueprint' for building a protein, straight from the DNA's master design.
• Key Features
  • 🔗 Binding Site: This is where the ribosome attaches itself.
  • 🛑 Start & Stop Codons: These are like the green and red traffic signals for the translation process. They say, "Begin the magic here!" and "Okay, job done, you can stop now!"
  • 💡 Fun Fact: One mRNA molecule isn’t a one-time-use ticket. It can be translated multiple times, but just like an overused concert ticket, it gets tossed if damaged or not needed anymore.

Example: Think of mRNA as a music sheet. Musicians (like ribosomes) read the notes (codons) and play the right tunes. If a note goes wrong or isn’t needed, the sheet gets replaced.

• 📜 Job: It's the matchmaker of the translation world, pairing the right amino acid with the right code on mRNA.
• Key Features
  • 🤝 Anticodon: This is a set of 3 bases that pairs up with the complementary codon on the mRNA.
  • 🍔 Amino Acid Attachment Point: This is where the correct amino acid gets attached. It's like a chef's assistant holding the right ingredient.
  • 💼 Unique Shape & Enzyme: Every tRNA has its unique 'look' and a dedicated enzyme buddy that ensures it picks up the correct amino acid.

Example: Imagine a chef (ribosome) trying to cook a burger (polypeptide). The tRNA is the sous-chef who hands the chef the right ingredients (amino acids) based on the recipe (mRNA).
