Answer:
Option (A).
Explanation:
The lac operon system in bacteria elucidates the process of lactose metabolism within the cell. The initial operon system was identified by Jacob and Monod. An operon is characterized as a cluster of genes transcribed together as a single RNA unit.
When both glucose and lactose are available in the media, the bacterium favors metabolizing glucose. The presence of glucose is recognized by the bacterial cell as the CAP-cAMP complex is essential for transcription, and its levels are reduced in glucose's presence. This mechanism effectively halts the transcription of lactose genes even when lactose is available.
Consequently, the right answer is option (A).
Answer:
Ribonucleotides pertain to RNA, while deoxyribonucleotides are part of DNA. More information is provided below.
Explanation:
Ribonucleotides consist of a ribose sugar and a nitrogenous base, but they do not include Thymine; instead, they have uracil. Deoxyribonucleotides, on the other hand, incorporate a deoxyribose sugar along with a nitrogenous base, which includes Thymine.
Answer:
Trojans Asteroids
Explanation:
Trojan Asteroids move in the orbit of a larger planet, where the gravitational forces of the sun and planets are in equilibrium, although I have uncertainity about the correctness of the answer. Good luck!
