AP Biology Questions on the Central Dogma of Molecular Biology

📚 Quick Study Guide

🧬
• Central Dogma: The central dogma of molecular biology describes the flow of genetic information within a biological system. It states that DNA makes RNA, and RNA makes protein.
📝
• Replication: DNA is duplicated to produce two identical DNA molecules.
🔬
• Transcription: DNA sequence is copied into RNA sequence.
🧪
• Translation: RNA sequence is used to produce a protein.
💡
• Reverse Transcription: Some viruses use reverse transcriptase to convert RNA back into DNA. This is an exception to the central dogma.
🔑
• Key Players: DNA polymerase (replication), RNA polymerase (transcription), ribosomes (translation), tRNA (translation).
🧮
• Mathematical Representation: DNA $\rightarrow$ RNA $\rightarrow$ Protein
