Answer:
Chromosomes are thread-like structures present in the nucleus of a eukaryotic cell, which carries genetic information from one generation to another. They play a vital role in cell division, heredity, variation, mutation, repair and regeneration.
- Chromosomes are the structures that contain DNA. These are found inside the nucleus of every plant and animal cell.
- Chromosomes are essentially shaped like a thread and are composed of nucleic acids such as DNA, RNA, as well as proteins.
- The primary role of chromosomes is to ensure that DNA is replicated and distributed correctly during cell division.
- Matthias Jakob Schleiden, Rudolf Virchow, and Otto Bütschli were the very first scientists to recognize structures observed by them as chromosomes.
