Somatic cells undergo mitosis while sex cells (ego cell and sperms) go through meiosis.
Cloning takes place when an adult nucleus is transferred to an egg cell and is stimulated to divide creating an exact copy of the adult source material. Today different animals are being cloned.

The Correct Answer and Explanation is :

The terms in the description relate to the processes of mitosis, meiosis, and cloning, which are vital in cell division and reproduction. Let’s go step by step and match the correct answers:

  1. Cell grows to its mature size, makes a copy of its DNA, and gets ready to divide
    • Answer: C. INTERPHASE
      Interphase is the phase where the cell grows, duplicates its DNA, and prepares for division.
  2. Chromatin in the nucleus condenses to form chromosomes. The nuclear membrane breaks down
    • Answer: D. PROPHASE
      During prophase, chromatin condenses into visible chromosomes, and the nuclear envelope dissolves.
  3. Chromosomes line up across the center of the cell
    • Answer: E. METAPHASE
      In metaphase, chromosomes align along the cell’s equator, preparing for the next phase.
  4. The spindle fibers draw each chromatin to each pole of the cell
    • Answer: A. ANAPHASE
      During anaphase, the sister chromatids are pulled apart toward opposite poles of the cell.
  5. Chromosomes begin to stretch out and lose their rod-like appearance. A new nuclear membrane forms around each region of chromosomes
    • Answer: B. TELOPHASE
      In telophase, chromosomes de-condense, and new nuclear membranes form around the two sets of chromosomes.
  6. Each daughter cell ends up with the same number of identical chromosomes and about half the organelles and cytoplasm
    • Answer: A. MITOSIS
      In mitosis, the cell divides into two identical daughter cells.
  7. DNA coils into chromosomes, the nucleolus and nuclear envelope disappear, the mitotic spindle forms, and synapsis (crossing-over) occurs
    • Answer: D. PROPHASE I
      This happens during meiosis I, where homologous chromosomes pair up and exchange genetic material.
  8. Tetrads line up randomly along the midline, spindle fibers attach to the centromere of each homologous chromosome
    • Answer: H. METAPHASE I
      Tetrads (pairs of homologous chromosomes) align at the metaphase plate in meiosis.
  9. Homologous chromosomes move to the opposite poles of the cell
    • Answer: A. ANAPHASE I
      In anaphase I of meiosis, homologous chromosomes are pulled to opposite poles.
  10. The chromosomes reach the opposite end of the cell, and cytokinesis begins
  • Answer: B. TELOPHASE I
    Telophase I marks the end of the first meiotic division, where the chromosomes reach opposite poles.
  1. Chromosomes move to the midline of the dividing cell, facing opposite poles of the dividing cell
  • Answer: H. METAPHASE II
    In metaphase II of meiosis, chromosomes line up at the center of the cell.
  1. The chromatids separate and move toward opposite poles of the cell
  • Answer: E. ANAPHASE II
    In anaphase II of meiosis, sister chromatids separate and move to opposite poles.
  1. A nuclear membrane forms around the chromosomes in each of the 4 new cells
  • Answer: F. TELOPHASE II
    Telophase II results in the formation of nuclear membranes around the newly separated chromatids, leading to the formation of four distinct cells.
  1. Occurs only in organisms that reproduce sexually
  • Answer: B. MEIOSIS
    Meiosis is the process that occurs only in sexual reproduction, resulting in gametes (sperm and egg).
  1. Sperm and egg cell
  • Answer: F. ZYGOTE
    A zygote is formed when a sperm and egg cell fuse during fertilization.
  1. Chromosomes of the same size and function
  • Answer: E. HOMOLOGUES
    Homologous chromosomes are pairs of chromosomes that are similar in size and function, one from each parent.
  1. Body cells
  • Answer: A. MITOSIS
    Mitosis produces two identical body cells (somatic cells).
  1. Chromosome 1 to 22
  • Answer: C. AUTOSOME
    Autosomes are non-sex chromosomes (chromosomes 1–22 in humans).
  1. Identical daughter cells can continue on with the cell cycle
  • Answer: A. MITOSIS
    Mitosis results in two genetically identical daughter cells that enter the next phase of the cell cycle.

Explanation:

  • Mitosis is the process of cell division that results in two genetically identical somatic cells, which helps in growth, repair, and asexual reproduction.
  • Meiosis, on the other hand, is the division of sex cells (sperm and egg), which reduces the chromosome number by half and introduces genetic diversity through crossing over and independent assortment.
  • Cloning involves transferring the nucleus of an adult cell into an enucleated egg cell, stimulating it to divide and develop into an organism genetically identical to the donor. This process mimics natural asexual reproduction, similar to mitosis but with some manipulation of the cellular environment.

In summary, mitosis and meiosis are distinct processes with different outcomes: mitosis results in identical somatic cells, while meiosis generates genetically diverse gametes for sexual reproduction. Cloning attempts to replicate an individual by mimicking natural cell division processes.
