Suppose an experimenter moves DNA sequences within a prokaryotic genome and puts the operator to the far end of the operon, past

the last structural gene [lac A], which of the following processes would likely occur when the cell is exposed to lactose Group of answer choices The inducer will no longer bind to the repressor. The operon will never be transcribed. The genes of the lac operon will be transcribed continuously. The repressor will no longer bind to the operator.

Answer:

The genes of the lac operon will be transcribed continuously

Explanation:

The operator is a sequence in the DNA which binds a repressor protein. THe operator is located upstream ('before') the structural genes of the operon.

When this repressor is bound to the operator it blocks the RNA polymerase from transcribing the structural genes.

If the operator is moved downstream (to the far end) of the operon, past the last structural gene, the repressor will stop being an obstacle for transcription and the RNA polymerase will always be able to transcribe the structural genes.

Cannabinoid receptors, located throughout the body, are part of the Endocannabinoid system which is involved in a variety of physiological processes including appetite, pain-sensation, mood, and memory.[1]

Cannabinoid receptors are of a class of cell membrane receptors under the G protein-coupled receptor superfamily. As is typical of G protein-coupled receptors, the cannabinoid receptors contain seven transmembrane spanning domains.[5] Cannabinoid receptors are activated by three major groups of ligands: endocannabinoids, produced by the mammillary body; plant cannabinoids (such as Cannabidiol, produced by the cannabis plant); and synthetic cannabinoids (such as HU-210). All of the endocannabinoids and plant cannabinoids are lipophilic, such as fat soluble compounds.

How does an enzyme change the activation energy for a reaction in a cell?
k0ka [10]

Answer:

The correct answer is option c. "Enzyme lowers the activation energy".

Explanation:

The activation energy is defined as the amount of energy needed for a reaction to take place. Enzymes catalyze reactions by lowering the activation energy, which speeds up the reaction and increases its rate. Enzymes put a substrate in its active site, which facilitates the reaction and makes more likely that it collides with its subsequent substrate.

Rufina [12.5K]

Answer:

The scientific study of life, called <u>Biology</u><u>, </u>can be organized around several themes. As the biological hierachy builds from molecules on up to ecosystems, each level has <u> emergent properties</u> that result from interactions among component parts. Life's basic unit of <u>structure and function</u> is the cell, which occurs in two basic forms- prokaryotic and eukaryotic . As organisms interact with the environment, <u>nutrients and chemicals</u><u> </u>cycle within an ecosystem, while energy flows one way from sunlight -> chemical energy -> heat. According to the core theme of <u>evolution </u>all of life is related by common descent. Life was diversified as <u>natural selection</u> had led to the gradual accumulation of adaptations that fit populations to the environment.

Explanation:

Emergent properties- Properties that is exhibited by a group of individuals as a result of  interaction among them.

Evolution- the process by which populations develop new characteristic and become more efficient than their ancestors.

Natural selection- A phenomena in which only fittest organisms of a population are allowed to survive in a given environment. This play a key role in evolution.
