Across
- 2. large biomolecules and macromolecules that comprise one or more long chains of amino acid residues
- 5. Having two different alleles in a gene
- 8. the inheritance of traits controlled by a single gene with two alleles, one of which may be completely dominant to the other
- 10. the name of the process in which proteins are produced
- 12. a polymer composed of two polynucleotide chains that coil around each other to form a double helix
- 15. genetic material that tells your body how to make proteins
- 18. Two chromosomes in a pair – normally one inherited from the mother and one from the father
- 19. the process of copying a segment of DNA into RNA
Down
- 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
- 3. when dominance does not occur and the non-dominant gene is not masked
- 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
- 6. the process by which the genome's DNA is copied in cells
- 7. the basic physical and functional unit of heredity
- 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
- 11. a nucleic acid present in all living cells that has structural similarities to DNA
- 13. a substance produced by a living organism which acts as a catalyst to bring about a specific biochemical reaction
- 14. a square diagram that is used to predict the genotypes of a particular cross or breeding experiment
- 16. Having two identical alleles in a gene
- 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
- 19. the process in which ribosomes in the cytoplasm or endoplasmic reticulum synthesize proteins
