RNA synthesis depends on RNA polymerases (RNAPs). This is the enzyme that faciliates copying a sequence of DNA which is the first step leading to gene expression. This multi-step process is important for researchers to understand especially in relations to studying how genetics influence disease processes.

Answer: The correct answer is It binds to the promoter region of a gene and adds new nucleotides to the growing end of nascent mRNA.

RNA polymerase is an enzyme that helps in the synthesis of mRNA ( messenger RNA) by using a template of DNA. This process is called transcription.

In this process, RNA polymerase first binds to a specific region in the gene called promoter, which marks the initiation of the transcription.

RNA polymerase by adding new nucleotide at the growing end of the nascent mRNA, synthesizes mRNA, which is complementary to the DNA template.

Thus, first option is the right answer.

KIM [24]

Answer:

Biodiversity is a measure that combines richness and evenness across species. It is often measured because high biodiversity is perceived a synonymous with ecosystem health.
