Chapter 17 From Gene to Protein Overview: The Flow of Genetic Information The information content of DNA is in the form of specific sequences of nucleotides The DNA inherited by an organism leads to specific traits by dictating the synthesis of proteins Proteins are the links between genotype and phenotype Gene expression, the process by which DNA directs protein synthesis, includes two stages: transcription and translation Copyright ? 2008 Pearson Education Inc., publishing as Pearson Benjamin Cummings Fig. 17-1 Concept 17.1: Genes specify proteins via transcription and translation How was the fundamental relationship between genes and proteins discovered?

Page 1 AP Biology: 2013 Exam Review AP BIOLOGY EXAM REVIEW GUIDE ?The price of success is hard work, dedication to the job at hand, and the determination that whether we win or lose, we have applied the best of ourselves to the task at hand.? Page 2 AP Biology: 2013 Exam Review CONCEPT 1 - BIOCHEMISTRY 1. CHNOPS- most common elements in all living matter 2. Bonds- ionic (transfer electrons), covalent (sharing- polar/unequal sharing and non-polar/equal sharing), hydrogen (weak bonds between hydrogen and negatively charged items), hydrophobic interactions (how non-polar compounds congregate together- lipids) 3. pH a. acid-base/ 0-14, # of H ions determines scale; logarithmic- pH 3 = 10-3 = 1/1000

Ch 18 - Regulation of Gene Expression Overview: Conducting the Genetic Orchestra Prokaryotes and eukaryotes alter gene expression in response to their changing environment In multicellular eukaryotes, gene expression regulates development and is responsible for differences in cell types RNA molecules play many roles in regulating gene expression in eukaryotes Concept 18.1: Bacteria often respond to environmental change by regulating transcription metabolic control occurs on two levels cells can adjust the activity of enzymes already present feedback inhibition - presence of enzyme a shuts down synthesis of more enzyme a by inhibiting activity cells can regulate the expression of the genes encoding the enzymes Operons: The Basic Concept

Intro to Biotechnology Mark Muller March 19, 2015 Chelsea Claverie Midterm Study Guide The Northern Blot detects the presence of certain RNA sequences, while the Southern blot can detect various DNA segments. Northern blot uses a gel electrophoresis, blot, RNA probes, and x-ray to determine the presence of a particular mRNA sequence that was immobilized and run in the electrophoresis. Southern blot uses an autoradiograph in combination with an electrophoresis gel to identify similarities between DNA. Similar DNA should travel the same distance in the electrophoresis, on the blot, and have the same binding sites from probes on the autoradiograph.

Gene Regulation in Eukaryotes The latest estimates are that a human cell, a eukaryotic cell, contains some 21,000 genes. Some of these are expressed in all cells all the time. These so-called housekeeping genes are responsible for the routine metabolic functions (e.g. respiration) common to all cells. Some are expressed as a cell enters a particular pathway of differentiation. Some are expressed all the time in only those cells that have differentiated in a particular way. For example, a plasma cell expresses continuously the genes for the antibody it synthesizes. Some are expressed only as conditions around and in the cell change. For example, the arrival of a hormone may turn on (or off) certain genes in that cell.

Chapter 18 Genomes and Their Revolution Overview: Reading the Leaves from the Tree of Life ? Complete genome sequences exist for a human, chimpanzee, E. coli and numerous other prokaryotes, corn, fruit fly, house mouse, orangutan, and others ? Comparisons of genomes among organisms provide information about the evolutionary history of genes and taxonomic groups ?Genomics is the study of whole sets of genes and their interactions ? Bioinformatics is the application of computational methods to the storage and analysis of biological data Concept 18.1: The Human Genome Project fostered development of faster, less expensive sequencing techniques ? The Human Genome Project officially began in 1990, and the sequencing was largely completed by 2003
