Question

can change over time in response to environmental cues, but this has no effect on gene expression.

1. In E. coli, lactose binds with: the lactose operon repressor, preventing it from binding to the operator. This allows the lacZ and lacY genes to be transcribed. the lactose operon operator, preventing it from binding to the repressor. This allows the lacZ and lacY genes to be transcribed. the lactose operon repressor, helping it bind to the operator. This prevents the lacZ and lacY genes from being transcribed. the lactose operon operator, preventing RNA polymerase from being recruited. This prevents the lacZ and lacY genes from being transcribed. the lactose operon operator, recruiting RNA polymerase. This allows the lacZ and lacY genes to be transcribed.

Explanation / Answer

Answers:

1). Operon of the E.coli has different sets genes that regulate the lactose metabolism. The lac repressor acts as a sensor for lactose. In the presence of lactose repressor unable to bind to the operator whereas, lactose is absent repressor binds to the operators that inhibits transcription.

Hence, the final answer is the lactose operon operator, recruiting RNA polymerase. This allows the lacZ and lacY genes to be transcribed

2). A histone code is: the pattern of chemical modification of the DNA wrapped around an individual histone
