The function of rna polymerase is to
a. catalyze the formation of phosphodiester bonds between ribonucleotides.
b. activate trnas.
c. cleave mrna to remove introns.
d. catalyze the formation of phosphodiester bonds between deoxyribonucleotids.

The correct answer will be option-A.

Explanation:

RNA polymerase is the enzymes which perform the process of transcription that synthesizes the RNA from one strand of the DNA.

These polymerase moves step-wise along the DNA strand adding one nucleotide in  5′-to-3′ direction. They catalyze the reaction by forming the phosphodiester bond between two nucleotides using the energy from the high energy bonds of ATP and form the linear RNA.

Thus, option-A is the correct answer.

it provides an alternative energy pathway for the reaction to proceed.

a catalyst is a substance that speeds up the rate of a chemical reaction but is not consumed during the course of the reaction.

catalysts increase the rate of reaction without being used up. they do this by lowering the activation energy needed. with a catalyst, more collisions result in a reaction, so the rate of reaction increases. different reactions need different catalysts.

a catalyst works by providing an alternative reaction pathway to the reaction product. the rate of the reaction is increased as this alternative route has a lower activation energy than the reaction route not mediated by the catalyst.

the nitrogen cycle provides nitrogen to the ecosystem from the atmosphere, ground and oceans. nitrogen is an important component of complex molecules such as amino acids and nucleotides, which lead to the creation of proteins and dna, the building blocks of all life. plants absorb nitrogen in the form of ammonium, nitrate ion and, on rare occasions, as amino acids. animals receive nitrogen necessary for biological processes from feeding on living or dead organic matter.
