A plant has one genome, a specific sequence of millions of basepairs of nucleotides. Yet how this genome is expressed can vary from cell to cell, and it can change as a plant goes through various life stages, from germination ...

Our genetic heritage is contained—and protected—in the nucleus of the cells that compose us. Copies of the DNA exit the nucleus to be read and translated into proteins in the cell cytoplasm. The transit between the nucleus ...

When genes were first discovered, the canonical view was that each gene encodes a unique protein. However, biologists later found that segments of genes can be combined in different ways, giving rise to many different proteins.
