S-8-2-2_Genetics and Heredity: Vocabulary Worksheet and KEY Genetics and Heredity: Vocabulary Worksheet Directions: Fill in the blanks with vocabulary terms from the list below. All organisms reproduce, or make more organisms that are similar to themselves. ______________________ also involves the passing of traits from one parent to offspring. The passing of traits from parents to offspring is called _____________________________. A _____________ is a set of instructions for an inherited trait. For example, a gene may contain the instructions that determine the color of a person’s eyes. The genes are located on structures inside a cell called _____________________________. After scientists recognized that chromosomes store the genetic information, they began an intensive search to learn more about the structure and chemical composition of chromosomes. Chromosomes are made from a chemical compound called________________________ ___________, abbreviated as ______________________. The genes that are passed from generation to the next are made of DNA. Knowing the structure of DNA would help scientists understand how DNA functions to control the development of traits in an individual. This is exactly what James Watson and Francis Crick were trying to do in the early 1950’s. Watson and Crick used data that other scientists obtained about the chemical composition of DNA to figure out its three-dimensional ___________.

All organisms reproduce, or make more organisms that are similar to themselves. REPRODUCTION also involves the passing of traits from one parent to offspring. The passing of traits from parents to offspring is called HEREDITY. Heredity is controlled by genes. A GENE is a set of instructions for an inherited trait. For example, a gene may contain the instructions that determine the color of a person’s eyes. The genes are located on structures inside a cell called CHROMOSOMES. After scientists recognized that chromosomes store the genetic information, they began an intensive search to learn more about the structure and chemical composition of chromosomes. Chromosomes are made from a chemical compound called DEOXYRIBONUCLEIC ACID abbreviated as DNA. The genes that are passed from generation to the next are made of DNA. Knowing the structure of DNA would help scientists understand how DNA functions to control the development of traits in an individual. This is exactly what James Watson and Francis Crick were trying to do in the early 1950’s. Watson and Crick used data that other scientists obtained about the chemical composition of DNA to figure out its three-dimensional STRUCTURE.
