Questions to Consider: Lisa Blackburn 1. Know the general work and findings of the following scientists: a. Gregor Mendal: Founder of the science of genetics.

Called the “father of immunology.” c. Watson and Crick: Two scientists who discovered the structure of DNA. d. Cohen and Boyer: Invented a method of cloning genetically engineered molecules in foreign cells. e. Erwin Chargoff: Discovered double helix structure of DNA. f. Rosalind Franklin: X-ray crystallographer who made critical contributions to the understanding of the fine molecular structures of DNA, RNA, viruses, coal, and graphite. g. Craig Ventner 2. What are three main parts of a DNA nucleotide? a. Five carbon sugar, nitrogen base, and a phosphate group. 3. What are the three bases found within DNA? a. Adenine, Cytosine, Thymine, and Guanine. 4. What are the DNA base pair rules? a. Adenine bonds with Thymine and Cytosine bonds with Guanine. 5. If one side of a DNA helix reads AAATCG what does its complimentary strand read? a. TTTAGC 6. How does a DNA double helix, chromosomes and genes relate to one another? a. A gene is a part of DNA that codes for a polypeptide or for an RNA chain that has a function of an organism. A chromosome is an organized structure of DNA. It is a single piece of coiled DNA containing many genes. 7. How do DNA and proteins relate to one another? a. A protein contains one or more polypeptides which is what a gene of DNA codes for. 8. What is the overall charge of a strand of DNA? a. The overall charge of a strand of DNA is negative. 9. How does DNAs charge help in electrophoresis? a. The negative charge of DNA causes the DNA to move towards the positive side and away from the negative side. 10. What is the goal of DNA electrophoresis? a. The goal of DNA electrophoresis is to spate the DNA fragments by size. 11. What is BLAST and what does it do? a. Basic Local Alignment Search Tool compares primary biological sequence information. It helps us know decipher unknown DNA. 12. What are restriction enzymes and how are they used in genetic engineering? a. A restriction enzyme is an enzyme that cuts DNA at specific nucleotide sequences. It is used in genetic engineering because when one knows the sequence of the gene, one is able to make targeted cuts to extract specific parts. This can be used in cloning. 13. What are “sticky ends” and how do they relate to restriction enzymes. a. “Stick ends” refers to the properties of the end of a molecule of DNA. This relates to restriction enzymes because when the DNA is cut by the restriction enzymes and placed into DNA by a vector, it has a sticky end so the DNA will attach easier. 14. What is bioinformatics and how does it relate to the human genome project? a. Bioinformatics of methods for storing, retrieving, and analyzing biological date, such as protein sequence, structure, function, pathways, and genetic interactions. This is related to the human genome project because by storing all this information it is easier to identify the human genes. 15. What basic characteristics are used to identify different fingerprints? a. Loop, Arch, Whirl are the basic characteristics used to identify different fingerprints. 16. What is the difference between a latent and patent fingerprint? a. Latent fingerprints are fingerprints not seen by the naked eye and you need to use graphite dust to take the fingerprint. Patent fingerprints are fingerprints you can see with the naked eye are you can take a picture of such print. Be able to: 1. Describe the process of gene splicing to create recombinant DNA. a. The process of gene splicing to create recombinant DNA is resulted from the use of laboratory methods to bring together genetic material from a source and placing it into another DNA sequence and making gene sequences that are not otherwise found in biological organisms. 2. Identify fingerprints. a. By looking at the fingerprint you can find out if the fingerprint has a loop, arch, or whirl. 3. Read a DNA electrophoresis gel. a. The shorter molecules move faster than the longer molecules. 4. Describe the process of DNA electrophoresis. a. You place the DNA into a well of the gel and charge the gel. The DNA moves away from the negative side (where the wells are) towards the positive side due to the negative charge of DNA. The shorter strands move faster than the longer strands causing gaps of the strands. Vocabulary Amino Acid Angstrom Bioinformatics Bioluminescence a) The basic building block of proteins (or polypeptides). Containing a basic amino group, an acidic carboxyl (COOH) group and a side chain (R - of a number of different kinds) attached to an alpha carbon atom. b)The fundamental building blocks of a protein molecule. A unit of length equal to one ten-thousandth of a micron (10-4 micron) or 10-10 of a meter with adenine. a) Refers to the generation or creation, collection, storage (in databases), and efficient utilization of data or information from genomics, combinatorial chemistry, proteomics, and DNA sequencing research. b) Examples of the data or information that is manipulated and stored include gene sequences, biological activity or function, pharmacological activity, biological structure, molecular structure, protein-protein interactions, and gene expression products or amounts. The emission of visible light by living organisms such as the firefly and various fish, fungi, and bacteria. Biopharmaceutical Bioprocessing Bioreactor BLAST CODIS DNA Analysis DNA Fingerprinting DNA Replication Double Helix Electroporation Forensics Forensic Scientist Genetic Engineering Pathogen Plasmid Protein Transformation A therapeutic product created through the genetic manipulation of living things, including (but not limited to) proteins and monoclonalantibodies, peptides, and other molecules that are not chemically synthesized, along with gene therapies, cell therapies, and engineered tissues. Using organisms or biologically derived macromolecules to carry out enzymatic reactions or to manufacture products. A container used for bioprocessing. Basic Local Alignment Search Tool (BLAST) is a sequence comparison algorithm optimized for speed used to search sequence databases for optimal DNA sequence alignments. Combined DNA index system. The testing of DNA samples that exists on the evidence collected from a crime scene. DNA fingerprinting is an individual's unique sequence of DNA base pairs, determined by exposing a sample of the person's DNA to molecular probes. The process of making an identical copy of a section of duplex (double-stranded) DNA, using existing DNA as a template for the synthesis of new DNA strands. The normal structural configuration of DNA consisting of two helices winding about the same axis. A process utilized to introduce a foreign gene into the genome of an organism. Involves the collection, analysis, and interpretation of evidence to solve crimes; its purpose is to create doubt as to the testimony of the witness. A professional that analyzes and interprets DNA samples as well as other forms of evidence collected from a crime scene. a) The selective, deliberate alteration of genes. b) The direct manipulation of genes for practical purposes. c) The technique of removing, modifying, or adding genes to a DNA molecule in order to change the information it contains. Refers to a virus, bacterium, parasitic protozoan, or other microorganism that causes infectious disease by invading the body of an organism (e.g., animal, plant, etc.) known as the host. An autonomous self-replicating genetic particle is usually of circular double-stranded DNA. A large molecule composed of one or more chains of amino acids in a specific order, required for the structure, function, and regulation of the body's cells, tissues, and organs. The modification of a genome by the external application of DNA from a cell of different genotype.
