Answer:
The correct answer is option a. "Transcription would not occur at high levels in either the presence or absence of arabinose".
Explanation:
The ara operon, also known as the L-arabinose operon, is a series of related genes that are transcribed within the same transcript and are all related to the metabolism of L-arabinose. Among the proteins translated from the ara operon, the AraC protein that binds to RNA Polymerase is the one that recognizes L-arabinose and enhances ara operon transcription in its presence. Therefore, if a mutation removes the gene that encodes for the AraC protein, transcription would not occur at high levels in either the presence or absence of arabinose.
Components of the dermis include: Blood vessels: Transport oxygen and nutrients to the skin and remove waste products.
Nutrient Leaching
Leaching is the process where dissolved nutrients in the
soil profile moves downward with percolating water. It is the loss of
water-soluble plant nutrients from the soil. The nutrients that seep through
the rooting zone may be recycled if roots grow deeper.
