What are autosomes?

Expert Solution
Step 1

Chromosomes are the rod shaped, dark stained bodies which are most prominently seen in the metaphase stage of mitosis/ or meiosis.  It consists of two chromatids joined together at a point called centromere. The chromosomes are composed of thread-like structures called chromatin fiber. They undergo coiling and supercoiling to form thicker and smaller chromosomes. The chromatin fibres are made of complex, helical strands of genetic material called DNA (Deoxyribonucleic acid). They are coupled together with histone proteins forming nucleosome units.
