PPT-DNA structure- Chromosomes

Chromosomes long pieces of DNA Chromosomes have genetic information and are passed on every time a cell divides chromosomes Dividing onion cells chromosomes nucelus cell wall Information flow in cells. Genetics and Heredity . See what you remember..  . 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.. chrmosomes.
