| In RNA, the pyrimidine thymine is replaced by: | |
| A regulatory unit in prokaryotic cells that controls the expression of structural genes. | |
| Having two different alleles for the same trait. | |
| The first step in the decoding of the DNA for protein synthesis. | |
| What is a cross between organisms with two different phenotypes that produces offspring with a third phenotype that is a blending of the parental traits? | |
| Macromolecules that contain carbon, hydrogen, and oxygen. Their common name is sugar or starch; largely energy sources in the body. | |
| The movement of water across a selectively permeable membrane. | |
| What states that two or more pairs of alleles segregate independently of one another during gamete formation? | |
| Physiological features possessed by different species that are similar in function, but that are not related in development or evolutionary origin. | |
| What states that the members of each pair of alleles separate when gametes are formed. A gamete will receive one allele or the other? | |
| Who proposed the theory of punctuated equilibrium? | |
| A network of fibers out-side the cell. It is used for such things as cell adhesion, cell- to- cell communication, and other regulatory functions. | |
| RNA that transfers amino acids to a growing peptide chain during protein synthesis. | |
| The union of the female gamete with the male gamete. The result is the formation of a zygote | |
| In genetics, all of the genes on a single chromosome. | |
| A theory that proposes phases of rapid evolution of new species, followed by long periods of little or no change. | |
| Functions as a site for spindle fiber attachment during cell division. | |
| Protein that is bonded to a carbohydrate, examples include: antigens, enzymes, and hormones. | |
| The contents of a cell excluding the nucleus | |
| What refers to the inheritance of quantitative traits, traits which are influenced by multiple genes, not just one? | |
| The pairing of homologous chromosomes during prophase I of meiosis. | |
| The appearance of similar structures in unrelated organisms. This may result from organisms adapting to similar environmental pressures. | |
