Genes tell cells how to make proteins.

nutrients can affect how the genes in cells work
All cells have genes
Chronic Myeloid Leukemia affects genes in the blood cells. Abnormal chromosomes develop and create new genes, these genes allow diseased blood cells to survive. You can learn more about Chronic Myeloid Leukemia at the Mayo Clinic website.
The genes affect the whole organism because your genes are in your DNA and in every cell there is 23 pairs of chromosomes so you are what you are from your genes and DNA. Genes code for the proteins in your cells. Your proteins do nearly everything in your cells. Therefore the genes you have determine how you function at a cellular level. In terms of chromosomes, they are your DNA wrapped very tightly around protein clusters called histones.
All your genes are present in your liver cells
The Cells hold the genes. Genes are a part of DNA, which is located in the Nucleus of a Cell.
A peculiar environment can affect genes and their expressions
yes it can affect the coding of genes.
Cancerous tumours are formed from cells which have had mutations in very specific genes which have allowed them to survive independantly of cells around them in the body. Some of these key genes code for growth factors and other proteins which affect normal body cells. Often the tumour cell mutations cause upregulation of these growth factors causing neighbouring healthy cells to be affected in unusual ways.
If the cells are from one individual, all will have the same genes except their sex cells which have 1/2 the number. A dog will have different genes from a cat. The genes make the cat different from the dog and human.
