Across
- 1. a process of cell duplication, or reproduction
- 3. the presence of a single set of chromosomes in an organism's cells
- 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.
- 8. the genetic makeup of an organism
- 9. A tool that helps to show all possible allelic combinations of gametes in a cross of parents with known genotypes
- 11. A molecule made up of amino acids
- 13. the process by which a cell makes an RNA copy of a piece of DNA.
- 15. the process in which cells make proteins.
- 16. a type of inheritance in which two versions (alleles) of the same gene are expressed separately to yield different traits in an individual.
- 17. The observable characteristics in an individual resulting from the expression of genes
- 18. A special form of cell division in which each daughter cell receives half the amount of DNA as the parent cell.
- 21. the process by which the genome's DNA is copied in cells
Down
- 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.
- 4. a substance produced by a living organism which acts as a catalyst to bring about a specific biochemical reaction.
- 6. The molecule inside cells that contains the genetic information responsible for the development and function of an organism.
- 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.
- 10. The presence of two identical alleles at a particular gene locus
- 12. the basic physical and functional unit of heredity.
- 14. having different alleles for a particular trait
- 19. A structure found inside the nucleus of a cell.
- 20. One of two or more DNA sequences occurring at a particular gene locus.
