Dna, Genes, and Chromosomes

DNA is the molecule that constitutes genes. The main component of each cell's DNA is found in its nucleus. The individual, very large DNA molecules of the nucleus are chromosomes, each of which consists of thousands of genes, and each cell of an individual plant species has the same DNA and chromosomal composition. Copies of all genes are transmitted from both parents to their offspring, accounting for inheritance, the principle wherein offspring resemble their parents.

The chemical structure of DNA allows it to store information and for that information to be incorporated into the design of developing cells and organs. DNA molecules are very long linear structures comprised of millions of repeating units. Segments, consisting typically of a few thousand of these units, constitute individual genes. Each gene carries the information that dictates the structure of a single protein. Proteins catalyze all of...
