however, a transversion occurred which changed the G nucleotide to T, what outcome(s) are likely? a. transcription levels would decrease because the promoter would be weaker b. nothing would happen because the promoter would not change the mRNA sequence c. the mutation would block RNA polymerase from binding to the DNA d. transcription levels would increase because the promoter would be stronger e. the bio gene does not require a functional promoter
Gene Interactions
When the expression of a single trait is influenced by two or more different non-allelic genes, it is termed as genetic interaction. According to Mendel's law of inheritance, each gene functions in its own way and does not depend on the function of another gene, i.e., a single gene controls each of seven characteristics considered, but the complex contribution of many different genes determine many traits of an organism.
Gene Expression
Gene expression is a process by which the instructions present in deoxyribonucleic acid (DNA) are converted into useful molecules such as proteins, and functional messenger ribonucleic (mRNA) molecules in the case of non-protein-coding genes.
- The promoter consensus sequence at the -10 BOX in the bio gene in E. coli was TAGACT; however, a transversion occurred which changed the G
nucleotide to T, what outcome(s) are likely?
|
a. |
transcription levels would decrease because the promoter would be weaker |

|
c. |
the mutation would block RNA polymerase from binding to the DNA |
|
|
d. |
transcription levels would increase because the promoter would be stronger |
|
|
e. |
the bio gene does not require a functional promoter |
