Genetics Story
Across
- 2. enzyme that aids in DNA or RNA synthesis
- 5. carries hereditary information
- 6. type of mutation that changes a single base pair
- 8. a nitrogenous base that has two rings
- 9. sequences of mRNA that leave the nucleus
- 15. a nitrogenous base only found in RNA
- 16. alternate form of a gene
- 17. this base pairs with adenine in DNA
- 18. type of mutation that results in a deletion or insertion of a base pair
- 19. chain of amino acids
- 20. nitrogenous bases that consist of one ring
Down
- 1. humans have 23 pairs of these
- 3. cleaves bonds with a nucleic acid
- 4. type of replication that DNA goes through with one parental strand and one daughter strand
- 7. the start codon
- 10. enzymes that degrade nucleic acids
- 11. a mutation in which the gene no longer functions
- 12. type of mutation that shows no change in phenotype
- 13. when genetic information is copied from DNA to form mRNA
- 14. includes a pentose sugar, phosphate group, and nitrogenous base
- 16. the configuration of the two strands in a DNA double helix
