Transcription & Translation Cheat Sheet
- Understand the central dogma of molecular biology - DNA is transcribed into RNA, which is then translated into proteins that carry out countless cellular tasks. Think of DNA as the recipe book, RNA as the recipe copy, and proteins as the delicious meal you create. Genome.gov: Transcription & Translation
- Recognize how transcription works - During transcription, RNA polymerase reads a DNA template and builds a complementary messenger RNA (mRNA) strand. This mRNA copy then carries the genetic blueprint from the nucleus to the cytoplasm in eukaryotic cells. BiologyCorner: Transcription & Translation Notes
- Learn the translation process - Translation occurs when ribosomes read the mRNA sequence in sets of three bases, assembling amino acids into a polypeptide chain. This chain folds into a functional protein that performs specific roles inside the cell. Monash University: Transcription & Translation
- Familiarize yourself with codons - Codons are three-nucleotide "words" on the mRNA that each specify a particular amino acid. Memorizing the codon table helps you predict which amino acid will be added next during protein synthesis. BiologyCorner: Codon Table & Notes
- Understand the role of tRNA - Transfer RNA (tRNA) molecules match their anticodon to the mRNA codon and deliver the correct amino acid to the ribosome. This ensures that proteins are built in the exact order dictated by the gene. Quia: tRNA Function List
- Know eukaryotic mRNA processing - In eukaryotes, the initial mRNA transcript is capped at the 5' end, spliced to remove introns, and given a poly-A tail at the 3' end. These modifications protect mRNA from degradation and help ribosomes recognize the message. Monash University: Transcription & Translation
- Grasp the degeneracy of the genetic code - The genetic code is called "degenerate" because multiple codons can code for the same amino acid. This redundancy can protect against the effects of point mutations. Monash University: Genetic Code Overview
- Identify start and stop codons - Translation always begins at the AUG start codon, which codes for methionine, and ends at one of three stop codons (UAA, UAG, UGA). Stop codons signal the ribosome to release the completed protein. Quia: Start and Stop Codons
- Recognize the impact of mutations - Changes in the DNA sequence can alter the mRNA message and potentially change the amino acid sequence of a protein. Some mutations have no effect, while others can drastically affect protein function. Quia: DNA Mutations and Effects
- Compare prokaryotic and eukaryotic synthesis - In prokaryotes, transcription and translation are coupled and occur simultaneously in the cytoplasm. In eukaryotes, transcription in the nucleus and translation in the cytoplasm are separated by the nuclear membrane. Monash University: Prokaryotic vs Eukaryotic Translation
