During transcription, the enzyme RNA polymerase binds to the: MCQ with Answer and Explanation

Explanation:
Growth hormone (somatotropin) is produced by the anterior pituitary. It promotes growth of bones, muscles, and other tissues. Deficiency causes dwarfism; excess causes gigantism or acromegaly.

Explanation:
During photosynthesis, water is split (photolysis), releasing oxygen as a byproduct. Respiration consumes oxygen, nitrogen fixation uses nitrogenase, transpiration releases water vapor.

Explanation:
Lysosomes are membrane-bound vesicles containing hydrolytic enzymes formed by the Golgi apparatus. The Golgi modifies, sorts, and packages proteins from the rough ER into vesicles; some become lysosomes. These organelles function in intracellular digestion and autophagy. Rough ER synthesizes enzymes, but the final packaging into lysosomes occurs at the Golgi. Hence, Golgi is sometimes called the 'traffic police' of the cell.
