BIO 181 – Verified Exam Questions (Mitosis, DNA Replication, Cell Cycle) | 2025/2026 | Arizona State University

BIO 181 – Verified Exam Questions (Mitosis, DNA Replication, Cell Cycle) | 2025/2026 | Arizona State University Description: This document contains verified and graded A+ questions and answers for BIO 181 – General Biology I at Arizona State University (ASU), specifically covering essential material related to mitosis, DNA replication, and the eukaryotic cell cycle for the 2025/2026 academic year. It is designed as a focused and efficient study guide for students preparing for unit exams or comprehensive assessments. Topics include the detailed stages of mitosis (prophase through cytokinesis), mechanisms of chromosome movement, and regulatory checkpoints across G1, S, G2, and M phases. The guide breaks down molecular processes such as DNA synthesis via helicase, primase, DNA polymerases I and III, ligase, and the formation of Okazaki fragments. It also explains key molecular control systems including cyclins, kinases, and the mitosis-promoting factor (MPF). Best suited for: Students in introductory biology or molecular cell biology Majors in biological sciences, pre-med, pre-nursing, and biotechnology Anyone preparing for exams covering the cell cycle, genome replication, and cell division mechanisms The content is delivered in a Q&A format, perfect for active recall practice and test preparation. Keywords: BIO 181, mitosis, cell cycle, DNA replication, Okazaki fragments, helicase, ligase, polymerase, cyclin, kinase, checkpoints, MPF, eukaryotic cell division, ASU biology exam
