Cells obtain instructions from hereditory proteins?
Answers
Genetics is the study of heredity, the process in which parents pass certain genes onto their children. A gene is a short piece of DNA—deoxyribonucleic acid, the hereditary material in humans and almost all other organisms. There are about 30,000 genes in each cell of the human body. Together, these genes make up the blueprint for the human body and how it works.
A person's appearance—height, hair color, skin color, and eye color—is determined by genes. Other characteristics affected by heredity include the likelihood of getting certain diseases, mental abilities, and natural talents.
An abnormal genetic trait passed down through families (inherited) may:
Have no effect on your health or well being—for example, it may just involve a white patch of hair or an extended earlobe
Be of minor consequence—for example, color blindness
Have a dramatic effect on your quality or length of life
