BIOD 101 MODULE 4 CERTIFICATION
EVALUATION 2026 EXAM SCRIPT FULLY
SOLVED QUESTIONS
◉Number of chromosomes in each somatic cell. Answer: 46 (23
pairs)
◉Cell cycle. Answer: Process of parent cell replicating its genetic
info and dividing into 2 new daughter cells
◉cytokinesis. Answer: division of the cytoplasm
◉interphase. Answer: G1, S, G2 phases. 90% of cycle time.
◉Gap phase 1. Answer: First phase, growth phase
◉Messenger RNA (mRNA). Answer: transfers genetic info from DNA
to ribosomes
◉site of protein synthesis. Answer: ribosomes
, ◉S phase. Answer: DNA duplication phase, lasts 10-12 hours
◉G2 phase. Answer: Second growth phase, when synthesis of
organelles and proteins needed for mitosis occurs. Lasts 4-6 hours.
◉centrosome. Answer: region that organizes microtubules for cell
division
◉centriole. Answer: short cylindrical protein filaments made of
tubulin. Plays role in formation of mitotic spindle.
◉Chromatin fibers become more coiled and densely packed, sister
chromatids are joined at the centromere and have an X shape..
Answer: Condensation stage of prophase
◉Cohesions. Answer: proteins holding sister chromatids together
◉Microtubules begin moving to opposite poles of cell. Answer:
Centrosome movement stage of prophase
◉aster. Answer: Radial microtubule proteins extending from each
centrosome
