Whether the DNA is from your finger, your liver, or your brain, the genes are all there. Depending on where the cell differentiated, different genes are activated while others are dormant. The genes in liver are also present in fingers, they just aren't activated. As of right now, scientists have no way of activating or deactivating a gene.
All cells have genes
genes genes
The genes are different because crossing over causes some of the genes on the homologous pair to shuffle, creating variation.
Genes tell cells how to make proteins.
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.
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.
Genes are cells that decompose in a plant cell.
There are more genes than chromosomes in skin cells.
40,000 genes
What do genes do to help carry out their functions
The human genome contains about 24,000 genes.
