  Which features of DNA is most important in determining the phenotype of an organism?  A Particular strand of DNA has the base sequence ATT-CCG. What is the base sequence of the complementary strand?  Why will knowledge of the human genome enable scientist to better understand proteins involved in human diseases? a.DNA contains the information used to make proteins. b.Nucleic acid molecules have shapes similar to those proteins c.The bases that make up DNA are also present in RNA d.Chromosomes can combine to form proteins Exploring Evidence of Evolution: Starter The sequence of nitrogenous bases TAA-GGC

  What is a fossil?  The remains or impression of a prehistoric organism preserved in petrified form or as a mold or cast in rock Practice

  Fossils provide evidence that life on Earth has changed as well as evidence about how that change has occurred. They also provide evidence of common ancestry among organisms. Fossils and Evolution

  Radiometric dating tells us how old fossils are and where they fit in Earth’s timeline. Radiometric dating also gives us the relative age of the Earth. Fossils and Radiometric Dating

  The study of how species are scattered across the planet and our understanding of plate tectonics provide us with evidence that evolution and natural selection have been shaping life on Earth for millions of years Evolution and Biogeography

  Examples of homologies (such as the claws of Hoatzin chicks and eggs of platypus) give us examples of intermediate organisms (organisms that have features similar to two totally separate groups of organisms).  Organisms that have features homologous to the features of other living organisms, as well as to fossils, provide evidence that organisms living today are linked to each other through common ancestors Evolution and Homologies

 Instructions  Fill in the graphic organizer on your handout by clicking through the next slide.  Each topic (textbox) in the graphic organizer is hyperlinked to a webpage that gives you information and explanations about that topic.  In slide show view, move the mouse over the topic and click. This will take you to the linked webpage.  Analyze and evaluate the information on each webpage.  Use that information to answer the questions on your student handout.  Although all answers can be found within the information on the linked web pages, other web resources may be used if needed.

  Think back to one of the many topics we’ve discussed in class so far this year. (Evolution, Cells, DNA, Ecology…) Write about the one you remember the most and a profession in which you would use this knowledge.  Must be one page. Exit: Writing Prompt 2
