have you been thinking what actually chromosome is?
i am writing this answer to help you out.
___________________________________________
=> chromosomes are required for passing genetic information from one generation to another.
=> these are thread like structures and are found in nucleus of cell. ( nucleus is basically the brain of a cell which controls many activities. )
=> they are composed of proteins and nucleic materials such as DNA and RNA.
both DNA and RNA are nucleic acids.
DNA=> deoxyribonucleic acid
RNA=> ribonucleic acid.
=> well DNA is folded up or coiled many times around some special proteins called histones to form the chromosome.
=> now they may have different structures. The structures depend on the place where centromere is present ( the constriction ). see the second picture+ 3rd picture.
=> now, two arms are formed. the shorter ones are called p arms and longer ones are called q arms.
=> sometimes another constriction may be seen on a chromosome other than centromere which is known satellite.
