Shared core processes support the relatedness of all eukaryotes. discuss how chromosome structure and function provides insights into the history of life on earth.

Chromosomes are the thread-like structure found in the nuclei of both animal and plant cells. They are made of protein and one molecule of deoxyribonucleic acid (DNA).

As the genetic material passes from parents to child, the chromosomes are responsible for containing the instructions that make the offspring unique while still carrying traits from the parent. In most organisms, one chromosome is inherited from the mother and the other is inherited from the father; to ensure that offspring carry traits from both parents. It's crucial that certain cells, like reproductive cells, have the correct number of chromosomes in order to function properly.
