IB SL Biology Lab Molecular Biology: Transformation and Electrophoresis Christina Qi 2/16/07 Aim: How can a plasmid be engineered to include a foreign piece of DNA and how does gel electrophoresis separate DNA molecules present in a mixture? Hypothesis: If the pGLO plasmid is inserted into competent Escherichia coli cells‚ then the transformed bacteria will be resistant to ampicillin and will glow green under UV light. If samples of DNA are cut using certain restriction

Examples of natural selection Emperor Penguins An example of natural selection comes from animals in the Arctic. If the initial population has brown skin penguins and penguins with white skin‚ predators the penguins will see brown skin and therefore the penguins eat brown leather more often. Having fair skin and help to survive‚ and the gene for white skin will dominate the population. But if the population then migrates to a forested area‚ the penguins with dark skin have an advantage because

B) they should share fewer homologous structures than two more closely related organisms. C) their chromosomes should be very similar. D) they shared a common ancestor relatively recently. E) they should be members of the same genus. 2) Within a few weeks of treatment with the drug 3TC‚ a patient’s

Evolution Unit: Objectives AP Biology Upon the completion of the textbook readings in Chapters 22-26 you should be able to: Chapter 22 1. Explain how the principle of gradualism and Charles Lyell’s theory of uniformitarianism influenced Darwin’s ideas about evolution. The basic idea of natural selection is that a population of organisms can change over the generations if individuals having certain heritable traits leave more offspring than other individuals. The result of natural selection

Studying Life Characteristics of Living Things What are some characteristics of living things? No single characteristic is enough to describe a living thing. Some nonliving things share one or more traits with living things. Living things share the following characteristics: made up of units called cells reproduce based on a universal genetic code grow and develop obtain and use materials and energy respond to their environment maintain a stable internal environment change over time
