Across
  1. 2. large biomolecules and macromolecules that comprise one or more long chains of amino acid residues
  2. 5. Having two different alleles in a gene
  3. 8. the inheritance of traits controlled by a single gene with two alleles, one of which may be completely dominant to the other
  4. 10. the name of the process in which proteins are produced
  5. 12. a polymer composed of two polynucleotide chains that coil around each other to form a double helix
  6. 15. genetic material that tells your body how to make proteins
  7. 18. Two chromosomes in a pair – normally one inherited from the mother and one from the father
  8. 19. the process of copying a segment of DNA into RNA
Down
  1. 1. the phenomenon of one variant of a gene on a chromosome masking or overriding the effect of a different variant of the same gene on the other copy of the chromosome
  2. 3. when dominance does not occur and the non-dominant gene is not masked
  3. 4. a threadlike structure of nucleic acids and protein found in the nucleus of most living cells, carrying genetic information in the form of genes
  4. 6. the process by which the genome's DNA is copied in cells
  5. 7. the basic physical and functional unit of heredity
  6. 9. one of two or more alternative forms of a gene that arise by mutation and are found at the same place on a chromosome
  7. 11. a nucleic acid present in all living cells that has structural similarities to DNA
  8. 13. a substance produced by a living organism which acts as a catalyst to bring about a specific biochemical reaction
  9. 14. a square diagram that is used to predict the genotypes of a particular cross or breeding experiment
  10. 16. Having two identical alleles in a gene
  11. 17. serves as a link (or adaptor) between the messenger RNA (mRNA) molecule and the growing chain of amino acids that make up a protein
  12. 19. the process in which ribosomes in the cytoplasm or endoplasmic reticulum synthesize proteins
