AP ESSAY ANSWERS: 16-20 1. Information transfer is fundamental to all living organisms. For TWO of the following examples‚ explain in detail‚ how the transfer of information is accomplished. A) The genetic material in one eukaryotic cell is copied and distributed to two identical daughter cells. B) A gene in a eukaryotic cell is transcribed and translated to produce a protein. C) The genetic material from one bacterial cell enters another via transformation‚ transduction or conjugation

INTRODUCTION Levels of organization (cell to biosphere) and characteristics of life Levels: Cells->tissue ->organs & organ systems->organisms->populations->communities->ecosystems-> biosphere Characteristics of life: Cell and Organization: Each cell can only do the job it is tasked with. Example: brain cells Energy Use and Metabolism: Energy is needed many organisms. Energy is utilized in chemical reactions Response to Environmental Changes: responds to stimuli Regulation and Homeostasis: ex:

Calvin Williams Chapter 20 1. Advances in recombinant DNA technology allow scientists to work with smaller fragments of DNA‚ give them more tools to dissect and analyze DNA‚ and also allow for them to make many copies of a strand of DNA. 2. Restriction enzymes are made by bacteria to cut up invading DNA. They target specific base sequences in the DNA and then work to cut out those sequences from the DNA. 3. When a restriction enzyme cuts out a portion of DNA‚ it will sometimes leave a sticky

Exam: Chapter 1 Study Guide 1. What are the 11 levels of organization? Briefly define each. Atom - fundamental units of matter‚ building block of all substances Molecule - atoms joined in chemical bonds (an association of 2 or more atoms) Cell - smallest unit of life Tissue - organized array of cells and substances that interact in a collective task Organ - structural unit of interacting tissues Organ System - a set of interacting organs Multicelled Organism - individual that consists

Chapter 20: DNA Technology Biotechnology: Use of living organisms to perform tasks. * Wine & cheese * Selective breeding * Antibiotic production * Recombinant DNA Restriction Enzymes * Bacterial enzymes: cut up foreign DNA * Specific: only but at recognition sequences * Palindromic: cut at the same base sequence on each strand‚ but in the opposite direction * The exposed bases provide “sticky ends” * H-bond to compliment bases of segments cut with same restriction

Lesson 3 Living things are made up of cells (based on a universal genetic code)‚ they obtain and use materials and energy to grow‚ develop‚ reproduce‚ respond to the environment‚ maintain a stable environment‚ and change over time. The study of biology revolves around several interlocking big ideas: the cellular basis of life; information and heredity; matter

Non-living structure made of cellulose. 2. Cell membrane/Plasma membrane • Semi-permeable/Partially permeable(Only certain parts can pass through it and some aren’t able). 3. • • • Cytoplasm Contains cell organelles. Food substances.
