Answer:
b. unable to terminate transcription of some genes.
Explanation:
Rho protein is a polypeptide with 419 residues and is found in prokaryotic cells such as bacteria.
Termination refers to the point where a signal is made for transcription to stop. This usually occurs when a part of the DNA known as the terminator is transcribed. The transcription of this part halts then transcription process.
A lack of the rho protein means transcription of some genes won’t be able to be stopped( terminated).
Answer:
Groups 4 to 7 are most likely to be undergoing the mitotic phase of the cell cycle.
Explanation:
Since the four proteins used p16, p18, p21, and p27 are inhibitors of cyclin-dependent kinases (CDK), their absence indicates that the cell is undergoing mitosis - the cell cycle is regulated by CDKs. In the absence of these inhibitors, the cell cycle moves on forward. Because the bar for DNA replication is longer in the case for groups 4 to 7, it is indicative of the fact that these cells have gone through the mitotic phase.
Hope that answers the question, have a great day!
The correct answer is letter A. Birth control does not cause the ovaries to release extra eggs. It does the opposite of it in fact. The other three choices are some of the effects of birth control methods that are available in the pharmaceutical company as oral or injected medications.
Answer:
Adaptive evolution
Explanation:
The radiation of finches in the Galápagos archipelago is the result of the natural selection process described by Darwin as adaptive evolution. Evolution is the process for which the organisms better adapted to its environment have more chances to survive and to reproduce, thereby leaving more offspring in the next generation.
Moreover, adaptive evolution refers to the mechanism for which species evolve by the emergence of advantageous mutations that are fixed through positive selection, thereby favoring the phenotypes that have higher adaptive fitness.
Answer:
The pesticides are worn off by the weather.
Explanation:
Becuase the chemicals can only work for a little in the pesticides so when bad weather comes around it finishes the rest of the chemicals in the pesticide.
Hope this Helps :)
