Bio 114 Exam 4 (UA) Questions and Answers Already Passed What is referred to as the "switch" in a DNA segment? The "switch" is known as the operator, a DNA segment typically located within the promoter region. What role does a repressor play in gene regulation? A repressor is a protein that attaches to an operator and obstructs RNA polymerase from attaching to the promoter. What is a corepressor? A corepressor is a molecule that works in conjunction with a repressor protein ...

UCI Bio 93 Final Review |100% Correct| A large % of offspring will have what phenotype? *Ans*The parental phenotype. A small % of offspring will have what type of phenotype and why? *Ans*they will have the non parental phenotype because linkage can break. Action potentials can travel _______________ distances and only in ___________________ direction. *Ans*long, one. Can genes be regulated during translation? *Ans*Yes! Genes are regulated all throughout gene expression, and both...

Operator The "switch" is a segment of DNA called an operator usually positioned within the promoter Operon the entire stretch of DNA that includes the operator, the promoter, and the genes that they control Repressor A protein that binds to an operator and physically blocks RNA polymerase from binding to a promoter site Corepressor a molecule that cooperates with a repressor protein to switch an operon off Inducer A specific small molecule that inactivates the repressor in an operon. Cell...
