  1. 1. a process of cell duplication, or reproduction
  2. 3. the presence of a single set of chromosomes in an organism's cells
  3. 5. Its principal role is to act as a messenger carrying instructions from DNA for controlling the synthesis of proteins, although in some viruses RNA rather than DNA carries the genetic information.
  4. 8. the genetic makeup of an organism
  5. 9. A tool that helps to show all possible allelic combinations of gametes in a cross of parents with known genotypes
  6. 11. A molecule made up of amino acids
  7. 13. the process by which a cell makes an RNA copy of a piece of DNA.
  8. 15. the process in which cells make proteins.
  9. 16. a type of inheritance in which two versions (alleles) of the same gene are expressed separately to yield different traits in an individual.
  10. 17. The observable characteristics in an individual resulting from the expression of genes
  11. 18. A special form of cell division in which each daughter cell receives half the amount of DNA as the parent cell.
  12. 21. the process by which the genome's DNA is copied in cells

  1. 2. the process in which ribosomes in the cytoplasm or endoplasmic reticulum synthesize proteins after the process of transcription of DNA to RNA in the cell's nucleus.
  2. 4. a substance produced by a living organism which acts as a catalyst to bring about a specific biochemical reaction.
  3. 6. The molecule inside cells that contains the genetic information responsible for the development and function of an organism.
  4. 7. a diagram that shows the occurrence and appearance of phenotypes of a particular gene or organism and its ancestors from one generation to the next, most commonly humans, show dogs, and race horses.
  5. 10. The presence of two identical alleles at a particular gene locus
  6. 12. the basic physical and functional unit of heredity.
  7. 14. having different alleles for a particular trait
  8. 19. A structure found inside the nucleus of a cell.
  9. 20. One of two or more DNA sequences occurring at a particular gene locus.
