  1. 6. Each gene's code uses the four nucleotide bases of DNA: adenine (A), cytosine (C), guanine (G) and thymine (T)
  2. 9. the heritable condition of possessing more than two complete sets of chromosomes
  3. 11. a linear organic polymer consisting of a large number of amino-acid residues bonded together in a chain, forming part of (or the whole of) a protein molecule
  4. 12. a sequence of three nucleotides forming a unit of genetic code in a transfer RNA molecule, corresponding to a complementary codon in messenger RNA
  5. 15. the process of translating words or text from one language into another
  6. 16. RNA consisting of folded molecules which transport amino acids from the cytoplasm of a cell to a ribosome
  7. 17. a person or company that finances or organizes a sporting event or theatrical production
  8. 19. a person who operates equipment or a machine
  9. 20. The sequence of DNA present in mature messenger RNA, some of which encodes the amino acids of a protein
  10. 22. any of a group of genes that control the pattern of body formation during early embryonic development of organisms
  11. 23. a sequence of three nucleotides which together form a unit of genetic code in a DNA or RNA molecule
Down
  1. 1. specifying cell identity and positioning during embryonic development
  2. 2. the insertion or deletion of nucleotide bases in numbers that are not multiples of three
  3. 3. an agent, such as radiation or a chemical substance, which causes genetic mutation
  4. 4. molecule in cells that forms part of the protein-synthesizing organelle known as a ribosome
  5. 5. the action or process of mutating
  6. 7. the action or process of differentiating
  7. 8. found in all living organisms as well as many viruses
  8. 9. a mutation affecting only one or very few nucleotides in a gene sequence
  9. 10. a segment of a DNA or RNA molecule which does not code for proteins and interrupts the sequence of genes
  10. 13. a written or printed representation of something
  11. 14. a nucleic acid present in all living cells that has structural similarities to DNA
  12. 18. a group of related genes that specify regions of the body plan of an embryo along the head-tail axis of animals
  13. 21. the form of RNA in which genetic information transcribed from DNA as a sequence of bases is transferred to a ribosome
  14. 24. a unit made up of linked genes which is thought to regulate other genes responsible for protein synthesis
