Are people’s chromosomes similar?

Chromosomes, chromatids, and chromatin share some of the same components. All three have DNA and histone proteins. All three are involved in the process of mitosis as cells divide.
What is the main function of chromosomes?
Chromosomes carry the basic genetic material DNA which is responsible to provide hereditary characteristics and genetic information to the various cells. The cellular functions are important for the growth and survival of living organisms.
What are the two main components of chromosomes?
The main components of chromosomes are DNA and proteins.
What is it called when chromosomes appear?
prophase. a cell division begins, the chromatin threads coil and shorten so that visible bar like bodies (chromosomes) appear.
