Which of the following statements is true? RNA polymerase can only add a nucleotide to the 5' end of a growing RNA chain. RNA polymerase can only add a nucleotide to the 3' phosphate end of a growing RNA chain. RNA polymerase can only add a nucleotide to the 5' phosphate end of a growing RNA chain. RNA polymerase can only add a nucleotide to the 3' –OH end of a growing RNA chain. none of the above is true.
Gene Interactions
When the expression of a single trait is influenced by two or more different non-allelic genes, it is termed as genetic interaction. According to Mendel's law of inheritance, each gene functions in its own way and does not depend on the function of another gene, i.e., a single gene controls each of seven characteristics considered, but the complex contribution of many different genes determine many traits of an organism.
Gene Expression
Gene expression is a process by which the instructions present in deoxyribonucleic acid (DNA) are converted into useful molecules such as proteins, and functional messenger ribonucleic (mRNA) molecules in the case of non-protein-coding genes.

RNA polymerase can only add a nucleotide to the 3' phosphate end of a growing RNA chain.
RNA polymerase can only add a nucleotide to the 5' phosphate end of a growing RNA chain.
RNA polymerase can only add a nucleotide to the 3' –OH end of a growing RNA chain.
none of the above is true.
The production of RNA from the DNA template is known as gene expression or transcription that occurs within the cytoplasm of prokaryotic cells and nucleus of eukaryotic cells. Different enzyme complexes have specific roles in the transcription process.
