Across
- 3. only in RNA
- 5. a sequence of three nucleotides which together form a unit of genetic code in a DNA or RNA molecule
- 6. a sequence of three nucleotides forming a unit of genetic code in a transfer RNA molecule, corresponding to a complementary codon in messenger RNA
- 9. pairs with thymine in DNA and uracil in RNA
- 10. copies DNA’s code & carries the genetic information to the ribosomes
- 11. the instructions to make molecules called proteins
- 13. a chemical compound that contains phosphorus
- 14. deoxyribose and ribose are examples of this
- 15. pairs with adenine only
- 16. along with protein, makes up the ribosomes
Down
- 1. A molecule that contains nitrogen and has the chemical properties of a base.
- 2. transfers amino acids to the ribosomes where proteins are synthesized
- 4. pairs with guanine only
- 7. The control center of the cell
- 8. pairs with cytosine only
- 12. contains genetic information and instructions for protein synthesis
- 13. made of amino acids and help build and work in the cells
- 16. contains information that has been copied from DNA
