A scientist compares the promoter regions of two genes. Gene A’s core promoter plus proximal promoter elements encompasses 70bp. Gene B’s core promoter plus proximal promoter elements encompasses 250bp. Which of the scientist’s hypotheses is most likely to be correct? a. More transcripts will be made from Gene B. b. Transcription of Gene A involves fewer transcription factors. c. Enhancers control Gene B’s transcription. d. Transcription of Gene A is more controlled than transcription of Gene B.
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.
A scientist compares the promoter regions of two genes.
Gene A’s core promoter plus proximal promoter
elements encompasses 70bp. Gene B’s core promoter
plus proximal promoter elements encompasses 250bp.
Which of the scientist’s hypotheses is most likely to be
correct?
a. More transcripts will be made from Gene B.
b. Transcription of Gene A involves fewer
transcription factors.
c. Enhancers control Gene B’s transcription.
d. Transcription of Gene A is more controlled than
transcription of Gene B.
