IB Biology: Chapter 1.6 Latest Update Graded A cell cycle all stages in the life cycle of a cell interphase composed of G1, S, and G2; = the growth of the cell. G1 - DNA transcription - protein synthesis (centrioles) - cell Respiration (produces energy) - growth of cell volume - organelles double (mitochondria & chloroplast) -increase in energy stored G0 the stage where cells are unlikely to divide (ex: neurons) S - synthesis of genetic material - DNA replication - dup...

GENETICS FINAL EXAMS| GENETICS TEST BANK|415 QUESTIONS WITH 100% CORRECT ANSWERS| LATEST UPDATE 2024|2025 - Crossover or DNA recombination occurs in eukaryotes between non-sister chromatids during prophase of meiosis Recombination also occurs between prokaryotes (via conjugation) and as a means of viral integration into a host cell The molecular mechanisms of crossover differ by species, but always in- volves the exchange of DNA between adjacent chromosomes These mechanisms are still the...

SimBio: Mitosis Explored Questions and Answers 100% Pass Mitosis is the sequence of events that splits ___________ cells in to two genetically equivalent cells eukaryotic cells Eukaryotic Cells A cell containing structures enclosed in membranes. Prokaryotic Cells lack a cell nucleus or any other membrane-bound cellular component. They are primarily unicellular organisms such as bacteria. Nuclear Envelope The membrane that encloses genetic material (DNA) in a eukaryotic cell. This membrane se...
