Which of the following relies on amolecule binding to the repressor to prevent the repressor from binding to the operator?
Vesnalui [34]

Answer:

d. induction

Explanation:

A repressor is a protein capable of inhibiting target gene expression by binding to both operator sites and gene silencers. A DNA-binding repressor inhibits the interaction between the RNA polymerase and the DNA promoter sequence, thereby suppressing transcription into RNA. Moreover, the RNA-binding repressor is a protein that binds to the messenger RNA (mRNA) molecule in order to prevent its translation into protein. An inducer can start transcription by interacting with the repressor, thereby separating it from the DNA operator sequence.

Which type of shift in plate boundaries creates ravines in the ocean floor?
goldenfox [79]

Answer:

Seafloor spreading occurs at divergent plate boundaries. As tectonic plates slowly move away from each other, heat from the mantle's convection currents makes the crust more plastic and less dense. The less-dense material rises, often forming a mountain or elevated area of the seafloor.

Griffith's experiments with S. pneumoniae were significant because they showed that traits could be transferred from one organis
Sliva [168]

Answer:

The correct answer will be- the traits can be heritable as the transferred material is heritable

Explanation:

Griffith experiment was performed on the <em>S. pneumoniae</em> bacteria which showed that some transforming material transformed the avirulent bacteria into virulent bacteria.

This indicated that traits controlled by the transforming material can be transferred from one organism to another organism. The researcher also concluded that the transforming material not just transformed the individual but the whole population as the trait was passed on to the generation.

Thus, the traits can be heritable as the transferred material is heritable is the correct answer.
