Arrange the following events for the synthesis of RNA in the correct order: Nucleophilic attack of the 3′ OH group of the first nucleotide at the α-phosphate group of the second nucleotide 5′ triphosphate occurs. Template specific rNTPs are bound. Several DNA bases are unwound, forming a stable complex. Polymerase finds a promoter region. A Mg+2-dependent isomerization of DNA takes place.

4, 3, 5, 2, 1

Explanation:

The process of syhthesis of protein is called trancription.

The proces sf transcription begin with the binding of RNA polymerase enzyme with a sequence of DNA called the promoter. RNA polymerase allows the unwinding of DNA bases forming a stable complex. In the next step, a Mg2+-dependent isomerization occurs, that produces a modified form of the open- promoter complex.RNA polymerase has one nucleoside triphosphate binding site which helps during elongation and binds any of the four common ribonucleoside triphosphates (rNTPs). Then a nucleophilic attack of the 3' hydroxyl (OH) present at the first nucleotide on the a - phosphorus gorup of the second nucleotide 5' triphosphate occurs that forms the first phosphodiester bond.

Hence, the correct order is 4, 3, 5, 2, 1.

Neurotransmitters are messengers responsible for communication between neurons. they are released from synaptic vesicles and are received by receptors.  the communication is referred to as neurotransmission. the following statement is true about neurotransmitters: a. they're stored in synaptic vesicles in the axon.
