General Biology I (BIOL 101) DNA Replication, Transcription, and Translation Exam Review
University of California, Los Angeles
General Biology I (BIOL 101) | Exam Review

Overview
A high-yield review of how genetic information flows from DNA to RNA to protein, plus the mutation patterns professors test.

Key topics
•DNA replication (enzymes and directionality)
•transcription + RNA processing
•translation (codons, tRNA, ribosome)
•mutations and protein effects

Suggested study tasks
•label a replication fork and explain each enzyme
•translate a short mRNA into amino acids
•predict how a frameshift changes the protein

Common pitfalls
•mixing transcription with translation
•forgetting 5' to 3' directionality
•assuming every mutation changes the amino acid sequence
