Anatomy & Physiology

1. this process is crucial in growth and development of the gene.
3. relatively small and mobile type of RNA.
7. three-base mRNA sequence.
8. chemical language the cell uses.
13. the functional unit of heredity.
15. contains complementary triplets that will be used as a model for mrna production.
18. carries hereditary information.
19. binds to the promoter of the gene.
21. nonsense regions.
22. essential in coding, decoding, regulation and expression of genes.
23. a strand containing the triplets that specify the sequence of amino acids in the polypeptide.

2. we have 23 of these distant structures.
4. connects to chromatids and chromosomes.
5. a change in the DNA sequence.
6. the creation of proteins by cells that use DNA, RNA and other enzymes.
9. gives the nucleus a grainy clumpy look.
10. a region of dna where transcription of a gene is initiated.
11. the production of rna from a dna. template.
12. a particle consisting of RNA and associated proteins found in large numbers in the cytoplasm.
14. the process of making the mrna string
16. three nitrogen bases form this.
17. basic proteins found in chromatin.
20. coding segments.
