Chromosomes are found within the nucleus of most living cells and consist of DNA that is tightly wound into thread-like structures..
What are chromosomes Ncert?
Chromosomes are the genetic material present in all the cells. They are present in the nucleus of a eukaryotic cell. They are a thread-like structure. Each chromosome of a eukaryotic cell contains DNA and associated proteins, known as histone proteins.
What are the two main components of chromosomes?
DNA and histone proteins are packaged into structures called chromosomes.
What are the two functions of chromosomes?
Chromosomes are thread-like structures present in the nucleus, which carries genetic information from one generation to another. They play a vital role in cell division, heredity, variation, mutation, repair and regeneration.
What is the function of the chromosomes?
Chromosomes are essential for the process of cell division, replication, division, and creation of daughter cells. Chromosomes are often called the ‘packaging material’ because it tightly holds the DNA and proteins together in the eukaryotic cells.
