Answer:
RNA polymerase
Explanation:
The RNA polymerase is an enzyme used in the transcription of genes in DNA to make mRNA. RNA polymerase binds on the promoter region based on the sequences that can be identified by the enzyme’s active site. A mutation can distort the interaction between the promoter region and the enzyme’s active site hence throttle up or inhibit transcription.
Answer:
Ribosomes, endoplasmic reticulum, Golgi apparatus, vesicles.
Explanation:
The endomembrane system in eukaryotes has divided the cell organelles into the structural and functional unit. This system plays an important role in the protein processing, its sorting and transport of protein.
The protein is prepared from the plasma cells. The antibodies is made on the ribosomes by the translation process. From the ribosomes, it will move to the endoplasmic reticulum for the glycosylation and protein folding. Then it moves to the golgi for the further protein packaging and processing. With the help of the vesicles it moves to its destination part in the cell.
Thus, the correct answer is option (d).
The answer to your question is a
<span>The correct answer is b. Option a is incorrect because these models can demonstrate scientific theories, but they don't prove scientific theories (you would need experiments for that). Option c is incorrect because the models aren't always representing something abstract (i.e. DNA is very real, just very small). Option d is incorrect because they don't precisely mimic something in nature, but instead help us visualize something in nature that is difficult to see or comprehend.</span>
