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.. (Game from Univ. Utah). Siguna. Mueller. PhD student in BMS, Univ. Wyoming. What is DNA?. Each cell needs instructions for its role in the body. What do these instructions look like?. The instructions come in the form of a molecule called DNA.. Humans have approximately . 20,000 – 30,000. genes that code for traits. . However, only have . 46 chromosomes. . Thus each chromosome must have . many genes. on them. . Often seen in . Sex-Linked Traits. Chromosomes carry genes in a linear sequence that is shared by members of a species.. Understandings:. Prokaryotes have one chromosome consisting of a circular DNA molecule. . Some prokaryotes also have plasmids but eukaryotes do not. .. and Genes.

What is DNA made up of?. 3.2.1. . Bacterial Chromosomes (prokaryotes). Most only have 1 chromosome.. Which means, it only contains a single copy of each gene (except during cell division when chromosomes are replicated).. Has circular DNA that contains all genes needed for basic life processes of the cell.. Lecturer . Dr. Samah A. Jassam BSc MSc PhD . MRSB. Al-Mustansiriya University . Collage of Pharmacy.
