anatomy
Across
- 3. carries the protein blueprint from a cell's DNA to its ribosomes
- 4. changing of the structure of a gene, resulting in a variant form that may be transmitted to subsequent generations
- 6. sequence of DNA needed to turn a gene on or off
- 9. DNA strand whose base sequence is identical to the base sequence of the RNA transcript produced
- 11. The four bases of DNA
- 13. transcription factors bind to, an enhancer and a promoter
- 14. x and y shaped structure in a nucleus
- 15. DNA strand that mRNA is built from
- 17. substance in the chromosome that contains DNA and protein
- 20. enzyme that copy's a DNA sequence into an RNA sequence
- 21. segment of a DNA or RNA molecule which does not code for proteins and interrupts the sequence of genes
- 22. process of creating protein molecules
Down
- 1. foundation for assembly of the kinetochore
- 2. three nucleotides forming a unit of genetic code in a transfer RNA molecule
- 5. process of making an RNA copy of a gene sequence
- 7. double helix,contains genetic information
- 8. provides structural support to a chromosome
- 10. RNA molecule that helps decode a mRNA sequence into a protein
- 12. RNA is converted into a sequence of amino acids
- 16. segment of a DNA or RNA molecule containing information coding for a protein
- 18. performs biological protein synthesis
- 19. sequence of 3 consecutive nucleotides that codes for a specific amino acid or signals the termination of gene translation
