DNA RNA protein synthesis quiz

🧬 Quick Study Guide

• 🔬 DNA (Deoxyribonucleic Acid): The genetic blueprint of life. It's a double-stranded helix containing the instructions for building and maintaining an organism.
• 🧪 RNA (Ribonucleic Acid): A single-stranded molecule involved in protein synthesis. Different types of RNA include mRNA, tRNA, and rRNA.
• 📝 Transcription: The process where DNA's genetic information is copied into mRNA. Enzyme involved: RNA polymerase.
• 🔄 Translation: The process where mRNA's genetic code is used to assemble amino acids into a polypeptide chain (protein). This occurs at the ribosome.
• 🔑 Codon: A sequence of three nucleotides in mRNA that codes for a specific amino acid.
• 📍 Anticodon: A sequence of three nucleotides in tRNA that is complementary to a codon in mRNA.
• 🧱 Central Dogma of Molecular Biology: DNA → RNA → Protein
