GENETICS Al-NASR International School Lesson Design & Prepared by ShahRukh Younas UNIT 4 LESSON 11 GREGOR MENDEL Al-NASR International School Lesson Design & Prepared by ShahRukh Younas UNIT 4 LESSON 11 Introduction to Genetics. Genetics is the study of how living things receive common traits from previous generations. These traits are described by the genetic information carried by a molecule called DNA. The instructions for constructing and operating an organism are contained in the organism's DNA. Al-NASR International School Lesson Design & Prepared by ShahRukh Younas UNIT 4 LESSON 11 DNA DNA is the hereditary material in humans and almost all other organisms. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus where it is called nuclear DNA. The information in DNA is stored as a code made up of four chemical bases, Adenine (A) Guanine (G) Cytosine (C) Thymine (T) An important property of DNA is that it can replicate, or make copies of itself.

A central tenet of molecular biology states that the flow of genetic information in a cell is from DNA through RNA to proteins: “DNA makes RNA makes protein”.

Human genetics, study of the inheritance of characteristics by children from parents. Inheritance in humans does not differ in any fundamental way from that in other organisms. Hereditary information is contained in genes, which are carried on chromosomes.

Genetic engineering is used by scientists to enhance or modify the characteristics of an individual organism. It can be applied to any organism, from a virus to a sheep. For example, genetic engineering can be used to produce plants that have a higher nutritional value or can tolerate exposure to herbicides.
