BIO 230 Exam Review (2026) – 100+ Verified Q&A on Genetics, Photosynthesis, Cell Division, Mutation | SFSU | San Francisco State University

This document features over 100 verified questions and correct answers compiled for students of BIO 230 – Introductory Biology at San Francisco State University (SFSU), tailored to the 2026 academic year. The content is labeled as already graded A+ and is structured in a clear Q&A format to support efficient self-study and high exam performance. The material spans key units in molecular biology, cell biology, genetics, and energy flow in living systems. Specific topics include: DNA/RNA structure and functions, including transcription, translation, codons, and polymerase function Mutation types (missense, silent, nonsense, frameshift) and agents (aflatoxin, mutagens, DNA adducts) Cell structure and classification, covering prokaryotes, eukaryotes, viruses, and organelles like ribosomes and chloroplasts Genetic inheritance and regulation, including genes, exons, non-coding DNA, telomerase, and tumor-related mechanisms Macromolecules (carbohydrates, proteins, nucleic acids, lipids) and their biological roles Photosynthesis and cellular respiration, including ATP, NADPH, chloroplasts, glucose production, carbon sources, and thylakoid function Cell cycle, mitosis, and meiosis, with chromosome behavior, crossing-over, homologous chromosomes, and chromatid replication Energy and matter transformation, including the carbon cycle, origin of biological mass, and solar energy conversion Each answer is concise and scientifically sound, with emphasis on key terminology and biological processes essential for first-year biology mastery. Who this is for: Students enrolled in BIO 230 at SFSU or similar Intro to Biology programs Undergraduate students in nursing, pre-med, biotechnology, and environmental science High school or college learners preparing for biology exams, concept reviews, or quizzes Learners looking to reinforce concepts on genetics, metabolism, cell structure, and photosynthesis This resource is ideal for exam prep, concept clarification, or structured content review and can complement textbooks, lectures, and lab materials.
