| The RNA molecules that carry copies of instructions for assembling amino acids into proteins. | Messenger RNA |
| The bits and pieces cut out that’s discarded while still in the nucleus of pre-mRNA molecules. | Intron |
| The way in which DNA, RNA, and proteins are involved in putting genetic information into action in living cells. | Gene Expression |
| The insertions and deletions of point mutations in which one base is inserted or removed from the DNA sequence. | Frameshift Mutation |
| Chemical or physical agents in the environment which change an organism’s genetic information. | Mutagen |
| Set of master control genes that regulates organs that develop in specific part of the body. | Homeotic Gene |
| Code for transcription factors that activate other genes the are important in cell development and differentiation. | Homeobox Gene |
| Is a gene located on a sex chromosome. | Sex-linked Gene |
| Means, “not coming apart, the most common error in meiosis when homologous chromosomes fail to separate. | Nondisjunction |
| Enzymes produced by bacteria that cut DNA molecules into smaller pieces. | Restriction Enzyme |
| Technique used by scientists to separate and analyze the differently sized fragments cut by restriction enzymes | Gel Electrophoresis |
| The process that allows only those animals with wanted characteristics to produce the next generation | Selective breeding |
| The process or technique of crossing dissimilar individuals to bring together the best of both organisms. | Hybridization |
| A technique used by biologist to make copies of gene. | Polymerase Chain Reaction |
| Is a gene that makes it possible to distinguish bacteria that carry the plasmid from those that don’t. | Genetic Marker |
| Analyzes sections of DNA that may have little or no function but that vary widely from one individual to another. | DNA Fingerprinting |
| The process by which organisms have changed over time. The verb evolve means to change over time. | Evolution |
| Is the process by which organisms with variations most suited to their local environment survive and leave more offspring. | Natural Selection |
| Is the study of where organisms live now and where they and their ancestors lived in the past. | Biogeography |
| Structures that are shared by related species and that have been inherited from a common ancestor. | Homologous Structure |
| Body parts that share common function, but not structure. | Analogous Structure |
| Are inherited from ancestors but have lost much or all of their original function due to different selection pressures acting on the descendant. | Vestigial Structure |
| Number of that an allele occurs in a gene pool compared with the number of alleles in that pool for the same gene. | Allele frequency |
| Is the presence or absence of dark bands; trait controlled by only one gene that controls shell banding has two alleles. | Single-gene trait |
| Trait controlled by two or more genes. | Polygenic trait |
| Form of natural selection in which individuals at one end of a distribution curve have higher fitness than individuals in the middle or at the other end of the curve. | Directional selection |
| Form of natural selection in which individuals near the center of a distribution curve have higher fitness than individuals at either end of the curve. | Stabilizing selection |
| Natural selection in which individuals at upper and lower ends of the curve have higher fitness than individuals near the middle of the curve. | Distributive selection |
| Change in allele frequencies as a result of the migration of a small subgroup of a population. | Founder effect |
| Situation in which allele frequencies in a population remain the same. | Genetic equilibrium |
| Principle that states that allele frequencies in a population remain constant unless one or more factors cause those frequencies to change. | Hardy-Weinberg principle |
| When individuals select mates based on heritable traits. | Sexual selection |
| Formation of a new species. | Speciation |
| Separation of a species or population so that they no longer interbreed and evolve into two separate species. | Reproductive isolation |
| Form of reproductive isolation in which two populations develop differences in courtship rituals or other behaviors that prevent them from breeding. | Behavioral isolation |
| Form of reproductive isolation in which two or more species reproduces at different times. | Temporal isolation |
| "classification system in which each species is assighned a two-part scientific name | Binomial nomenclature |
| Group of closly related species; the first part of the scientific name in binomial nomenclature | Genus |
