Answer:
RNA synthesis proceed in 5' to 3' direction.
Explanation:
The process of formation of RNA molecule from the DNA template is known as transcription. The transcription process is necessary for the gene expression.
The process of RNA synthesis always occur in the 5' to 3' direction. The RNA polymerase moves from the 3' strand and adds the polynucleotide and RNA synthesis in 5' to 3' direction. The anti parallel nature of the nucleotide causes the RNA synthesis in 5' to 3' direction.
The answer is d) organic chemistry
