But the inner secret of heredity remained a mystery until the last decade. When it was solved, it also revealed the inner secrets of all living cells. Dye Stain Cells The early microscopes of 1600s the inspired great excitement. Scientists saw that wood and animal tissues were made from tiny cells and a whole new miniature world became visible. Later, more powerful microscopes revealed details of the living cell and microbiologists devised ingenious techniques to trace its miraculous chemical operations. Most of the cell tissue is the cytoplasm of membranes and jellified protoplasm. But the most fasci- naming item is the tiny nucleus inside every living celL Finally, dyes were found to stain cell specimens for microscope slides. This revealed that the nucleus is a bundle of tight red wads. They were called chromosomes, meaning colored bodies. But even our best microscopes c a n no t define them clearly when the cell is in its normal phase. However, the chromosomes are revealed with all their miraculous talents when a cell divides to become a pair of twins. Then the 46 chromosomes in the nucleus of a human cell uncoil and become fuzzy, stringy little rods. Each rod duplicates itself and splits lengthwise. The two copies move apart, the cell divides Into two cells, each with its own duplication the somes of original 46 chromo- Improved that microscopes the chromosomes are bumpy strings of beads.

They identified dioxyribo-nuclei-c acid and the complex structure of its long molecules, twisted in double strands like spiral staircases. Here, in this fabulous DNA, they found the innermost secrets of heredity. They also found that this same DNA is the basic blueprint that governs the multitude of chemical activities that go on in every living cell. The cell of plants and animals also contain chromosomes, though some specie have more and others less than human ceils. Every human cell has 46, 23 inherited from each parent. Each chromosome is a string of 1,000 or more genes, each bearing an inherited trait. An adult human body has about 60.000 million cells. The nucleus is but a small part of each and every cell.
