Choose the correct sequence of the prokaryotic operon. A) gene, operator, promoter B) promoter, operator, gene C) operator, prom
Harrizon [31]

Answer:

The correct answer is option B, that is, promoter, operator, gene.

Explanation:

In a prokaryote, just in front of the operator, the promoter is located, and just in front of the structural genes, the operator is located. All these in combination give rise to an operon.  

Any gene, which codes for an enzyme or a structural protein is termed as a structural gene, in the lac operon, a structural gene codes for three distinct kinds of enzymes. A short sequence of DNA is situated just in front of the structural gene, which is known as the operator. An operator functions as a switch for transcription, that is, it monitors whether the process of transcription will take place or not.  

Just in front of an operator, a sequence of a promoter is present, and for the transcription and translation of all the structural genes, the RNA polymerase needs to combine first with the promoter. In case, if no transcription is to take place, then the operator allows the repressor to bind with it and prevent the attachment of RNA polymerase with the promoter. Hence, the correct sequence of a prokaryotic operon is a promoter, operator, and gene.

lukranit [14]

Answer: A. mechanisms for which activity is primarily triggered and shaped by the incoming stimulus information.

Explanation:

Bottom-up mechanism is a process in which a body perceives an incoming stimulus and certain physiological changes occurs in the body working in the direction of upwards that is the signals are transferred to the brain so that the brain could interpret the stimulus. This mechanism suggests the fact that our perceptual experience is based upon the sensory stimuli.
