AP Bio Unit 6 MCQ Cheat Sheet
- DNA Double-Helix & Base Pairing - Picture your favorite twisted ladder: that's DNA's double-helix! The rungs are A pairing with T and G pairing with C, ensuring a perfect match every time for accurate information storage and replication. Learn-Biology AP Bio Guide
- Semi-Conservative DNA Replication - Every new DNA molecule keeps one old strand and one fresh strand, thanks to helicase unzipping the helix and DNA polymerase building new strands in the 5' to 3' direction. Don't forget ligase stitching up any gaps like a biological seamstress! Learn-Biology AP Bio Guide
- Transcription & Translation Workflow - In transcription, DNA scripts an mRNA copy; in translation, that mRNA is decoded by ribosomes into an amino acid chain. tRNA brings the right amino acids, turning genetic code into living proteins. Learn-Biology AP Bio Guide
- Prokaryotic Gene Regulation (Operons) - Bacteria use operons like on/off switches to control gene clusters - think of the lac operon flipping on when lactose shows up. This adaptive system saves energy and resources in changing environments. Learn-Biology AP Bio Guide
- Eukaryotic Gene Regulation - Eukaryotes fine-tune genes with transcription factors and epigenetic tags like DNA methylation or histone acetylation. These modifications can silence or spotlight genes without altering the underlying DNA letters. Learn-Biology AP Bio Guide
- Mutations & Their Impact - A single base swap can rewrite a whole story - like the point mutation in hemoglobin leading to sickle cell anemia. Understanding mutation types helps you predict how proteins might fold or malfunction. BioInteractive Resources
- Horizontal Gene Transfer - Bacteria borrow genes from neighbors through transformation, transduction, or conjugation, creating rapid genetic diversity. This microbial gene swap explains how antibiotic resistance can spread in a flash. Learn-Biology AP Bio Guide
- Biotechnology & CRISPR - Modern tools like CRISPR-Cas9 let scientists snip and rewrite DNA with surgical precision, opening doors to gene therapies and engineered crops. It's like having molecular scissors guided by a customizable GPS. Learn-Biology AP Bio Guide
- Virus Structure & Replication - Viruses are genetic pirates hijacking host cells to churn out new viral particles. Knowing capsid designs and replication tricks is critical for anti-viral strategies and vaccine development. Learn-Biology AP Bio Guide
- The Central Dogma - DNA → RNA → Protein sums up the flow of genetic information in every living cell. This elegant framework underlies everything from enzyme action to your brilliant brainpower. YouTube Summaries: Central Dogma
