What is the role of rna polymerase in transcription?
it binds to the promoter region of a gene and adds new nucleotides to the growing end of nascent mrna.
it binds to the promoter region of a gene and terminates the process of transcription.
it binds to the coding region and adds nucleotides to the growing end of the dna.

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.

humans can cause extinction of a species through overharvesting, pollution, habitat destruction, introduction of invasive species (such as new predators and food competitors), overhunting, and other influences. explosive, unsustainable human population growth is an essential cause of the extinction crisis.

surface mining destroys mountain tops, landscapes, forests and wildlife habitats. on top of that, it leads to soil erosion and destruction of agricultural land. the landscape changes can also disrupt river channels and streams, which leads to flooding. which, can destroy plant life and other animals as well.
