Question

Which of these sentences characterizes the regulatory mechanisms of gene expressions in organisms?. . . . A.They help the organism to utilize all the metabolic resources inside their body completely, which sometimes may lead to lack of metabolites.. . . . B.They save energy and metabolites and help the organisms to respond to the environmental changes.. . . . C.They utilize a high amount of energy, always lead to catabolic processes, and may lead the organism to exhaustion..

Answer 1

The sentence “they save energy and metabolites and help the organisms to respond to the environmental changes” characterizes the regulatory mechanisms of gene expressions in organisms. The correct answer between all the choices given is the second choice or letter B. I am hoping that this answer has satisfied your query and it will be able to help you in your endeavor, and if you would like, feel free to ask another question.

Answer 2

The correct option for the above statement is:

B. They save energy and metabolites and help the organisms to respond to the environmental changes.

Explanation:

Studies of organic phenomenon generally live the assembly of template RNA. Most mechanisms that management organic phenomenon do thus by dominant transcription, the synthesis of template RNA.

 But there are other mechanisms for dominant the speed of supermolecule synthesis that occur downstream. Any step of the organic phenomenon is also modulated, from the DNA-RNA transcription step to post-translational modification of a super molecule. The subsequent may be a list of stages wherever organic phenomenon is regulated, the foremost extensively used purpose is Transcription Initiation: chromatin granule domains and transcription.
