BIOL 1201 – 100 Exam Questions on Mitosis, Meiosis, Genetics & DNA Replication – 2025/2026 – Louisiana State University

This document contains 100 verified multiple-choice questions and answers for BIOL 1201 Exam 3 at Louisiana State University, prepared for the 2025/2026 academic year. The questions thoroughly cover cell division processes—including the full eukaryotic cell cycle (G1, S, G2, M phases), mitosis, and meiosis I and II—detailing key structures such as centromeres, spindle fibers, centrosomes, and the role of microtubules. Students are tested on binary fission, cytokinesis in plant vs. animal cells, and cell cycle regulation mechanisms like checkpoints, cyclins, CDKs, and MPF. Additional focus is placed on sexual and asexual reproduction, chromosomal behavior, and inheritance patterns. The document explores Mendelian genetics concepts such as dominance, codominance, incomplete dominance, polygenic inheritance, and epistasis, as well as true-breeding lines, P/F1/F2 generations, and genetic testing methods like CVS and amniocentesis. It also includes comprehensive coverage of DNA replication—highlighting the roles of helicase, DNA polymerases I and III, ligase, Okazaki fragments, topoisomerase, and strand directionality. This makes the resource especially useful for mastering molecular biology and understanding how genetic information is copied and passed on. This exam prep material is ideal for undergraduate students in biology, biomedical sciences, biochemistry, and related fields. It supports both test preparation and active review for foundational topics in cellular and molecular biology.
