Assuming that the rest of the genome is normal, cells with an inactivating mutation in one copy of a tumor-suppressor gene with the second copy of the gene still wild-type are most likely to show no changes in DNA sequence.
Tumor suppressor genes are normally present in the body. These function properly and keep processing the cell growth and cell death (apoptosis). It can also suppress tumor development. If both copies of a tumor suppressor gene is mutated then only it cause a change in cell growth and form a tumor. So these are recessive in nature. And if only one gene is mutated then it shows no mutation. When a tumor suppressor gene is inactivated by mutation, the protein it encodes is not produced or does not function properly, and as a result, uncontrolled cell division can occur. Such mutations can contribute to the development of cancer.

Clouds appear white because of scattering. The droplets in the clouds are huge compared to the wave length of light, so all wavelengths scatter at the same time. Hope this helps! :)
I believe Formed in our bones, hydroxyapatite crystals are mineral complexes comprised of calcium and phosphorus. The hardness and rigidity of bone is due to the presence of mineral salt in the osteoid matrix, which is a crystalline complex of calcium and phosphate. Calcified bone contains about 25% organic matrix, 5% water and 70% inorganic mineral.
Photosynthesis is the process in which light energy of the sun is converted to chemical energy. ... The oxygen so released is used in the respiration process to break down complex molecules (generated in photosynthesis) and releases energy in the form of ATP (adenosine triphosphate) molecules.
