Domain — Biology for the CUET Exam

Biology is required for MBBS, BDS, B.Sc. Nursing, and life-science admissions. CUET Biology is tightly aligned with NCERT. Genetics and evolution, human physiology, and biotechnology are perennially high-yield chapters with the most questions per CUET paper.

Common failure modes

These are the patterns that cause most candidates to lose marks on this topic. Recognising them in advance is half the work.

  • !Confusing mitosis and meiosis stages — especially prophase I sub-stages
  • !Misidentifying hormones and their target organs in human physiology
  • !Overlooking biotechnology chapters (recombinant DNA, PCR) despite their high CUET weight

Study tips

  • 1Draw and label cell diagrams (mitochondria, chloroplast, nucleus) from memory weekly.
  • 2Make a hormone table: gland, hormone name, function, and deficiency disease.
  • 3Read NCERT Biotechnology chapters (Class 12, Chapters 11–12) carefully — they are consistently tested.

  1. 1

    The process of crossing over in meiosis occurs during:

    • ALeptotene
    • BZygotene
    • CPachyteneCorrect
    • DDiplotene
    Why this answer?

    Crossing over (exchange of chromosomal segments between homologous chromosomes) occurs during pachytene of Prophase I of meiosis I. This is the stage when tetrads (bivalents) are fully formed.
