1. The living thing is made up of cells. A cell is the building block of all organisms. It is the smallest unit of organization in a living thing. They contain the organism's hereditary information (DNA).
2. DNA is a molecule which stores genetic information. A chromosome is a structure that is made of a chemical known as deoxyribonucleic acid(DNA) as well as protein. Chromosomes are found in the nucleus of cells. Chromosomes contain many genes. A gene is a molecular unit of heredity.
3. Monozygotic twins occur when a single egg is fertilized to form one zygote which then divides into two separate embryos. Dizygotic twins usually occur when two fertilized eggs are implanted in the uterus wall at the same time.
