Chapter Eight

3. expression of the genotype creates traits
7. segment of DNA that controls transcription of structural genes by binding to a repressor protein
9. inhibits gene expression and decreases protein synthesis
10. the loss of base pairs
13. the addition of base pairs

15. turns on gene expression
16. dsDNA is used to synthesize an RNA molecule

1. the sum of all gene types
2. segment of DNA where RNA polymerase initiates transcription of structural genes
4. groups of three nucleotides in each mRNA that each encode for an amino acid
5. one base for another pair
6. set of operator and promoter sites and the structural genes they control
8. the study of inheritance or heredity of living things
11. mRNA is used to produce a protein
12. adenine pairs with thymine, guanine pairs with cytosine
