The gene that is actually working, or activated, is called dominant, its silent, unactivated partner is a recessive gene(i42)
Genes direct the assembly of mRNA, the process called transcription. The mRNA carries this information to the ribosomes, where proteins are manufactured; this process is called translation(i66)
The obese mouse gene plays an important role in determining the amount of fat the body will hold(i86)
The gene pool, the common heritage of our species, is acquiring genes that can cause more and more cases of Down syndrome, sickle-cell anemia, diabetes, and so on. In a sense, we are the victims of our own success. By helping the genetically disadvantaged to survive, we endanger our common heritage(i103)
Your phenotype is the individual you, as opposed to the blueprint(i111)
As a cell ages, it makes more of some proteins and less of others. In geneticists' terms, gene expression changes(i130)
