"The book...is, in fact, a short text on the many practical problems...associated with translating the explosion in basic biotechnological research into the next Green Revolution," explains Economic Botany. Measure content performance. Making proteins is far from DNA's only role. Genes only make up between 1% and 5% of the human genome. Proteins do most of the work in the cell. The DNA stays safely tucked away in the nucleus so we need a working copy of the information. The four bases are: The bases pair up with each other—A with T and C with G—to form units known as base pairs. Today, genetic research has led to the development of targeted drugs that can treat cancer with less damage to non-cancerous cells. The building blocks of DNA are called nucleotides.

The sequence of DNA bases is arranged into chromosomes, most of which contain the instructions to build an amino acid. Each gene has the instructions for making a specific protein, and each protein does a specific job in the cell. Nuclear DNA is known as the molecule of life and contains the genetic instructions for the development of all living organisms. It sends instructions to the ribosomes, where the proteins are made and sent to the Golgi complex. Short answer: A species' (or an organism's) genome consists of chromosomes, i.e., large DNA molecules that encode genes (and much more). A rival company, Vitagene, tells me something similar. the strands are oriented in opposite directions, In double-stranded DNA, 3'- ATCGCAG - 5' would be paired with. A gene is a portion of a cell's DNA that is programmed to make a specific protein. Rough ER --> Golgia apparatus --> lysosome.
