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. Explore more about chromosomes or other related topics by registering at BYJU’S
