Questions and Answers

What are telomeres?

  • Proteins involved in meiosis
  • Structures responsible for cell expansion in plants
  • Molecules of DNA containing thousands of genes

  • What dictates growth in plants?

  • Presence of telomeres
  • Cell division only

  • Cell expansion only
  • What is the characteristic of chromosome number in somatic cells of a species?

  • It varies greatly within the same species
  • It is determined by the number of genes in the cell
  • It is consistent for every somatic cell in an organism of a given species (correct)
  • It is directly related to plant cell cycle

    Study Notes

    Cellular Reproduction

    • Telomeres are repetitive DNA sequences (TTAGGG in humans) that protect the ends of chromosomes from deterioration or fusion with neighboring chromosomes.

    Plant Growth

    • Hormones, particularly auxins, dictate growth in plants.

    Chromosome Number

    • In somatic cells of a species, the characteristic chromosome number is diploid (2n), meaning two sets of chromosomes, one inherited from each parent.

    Olea Europaea (Olive Tree)

    • Olea europaea, the olive tree, has 46 chromosomes per cell.

    Meiosis

    • Meiosis is a type of cell division that reduces the number of chromosomes by half, producing four non-identical daughter cells, each with a unique combination of genetic traits.
    • The role of meiosis in the cell cycle is to produce gametes (sperm or egg cells) for sexual reproduction.

    Telomeres and Their Function

    • Telomeres function as a protective cap, preventing the loss of genetic information during DNA replication and protecting the chromosome from degradation.
