Rough ER - protein synthesis, transport of proteins throughout the cell
Smooth ER - lipid synthesis and cell detoxification
Answer:
Negatively repressible.
Explanation:
A control which occurs through repressor is known as negative control which may be inducible or repressible.
When a small molecule named as allolactose binds this repressor it leads to allosteric repulsion which removes repressor from the operator as a result of which RNA polymerase can start transcription. Allolactose is therefore known as inducer because it induces lac operon expression.
But here, the operator is active (induced) already so there is no need to induce the operon which means that it can only be repressed so that transcription could stop. So the answer is negatively repressible operon.
Answer:
The correct answer is "reduced initiation of translation".
Explanation:
The ribosome-binding site (RBS) is the sequence of DNA responsible for the recruitment of a ribosome, which results in the initiation of protein translation. A mutation that specifically occurs in a bacterial RBS may result in a reduced initiation of translation. A mutated RBS would likely fail to recruit the ribosome, which will affect the level of initiation of translation.
Each cell in the human body contains about 25,000 to 35,000 genes.
