Which action is one role of rna polymerase during transcription? to produce a start sequence to switch uracil with thymine on the exposed gene to break down an already existing protein to build a molecule of mrna

The correct answer will be option-to build a molecule of mRNA

Explanation:

The RNA polymerase is the enzyme which acts during the process of transcription which produces the transcript molecule of the gene called mRNA.

RNA polymerase as the name suggests help polymerise the RNA molecule from the DNA by copying the DNA sequence and adding specific complementary bases to form the mRNA molecule.

The RNA polymerase enzyme forms mRNA molecule once the enzyme binds the promoter sequence located upstream of the regulatory sequence of the gene.

Thus, the selected option is the correct answer.

Explanation:

I took the test and got it right

one characteristic that is shared by all is a soft body. many

of these invertebrate animals also have an outer shell to protect their

body. oysters, clams, snails, and mussels are all mollusks. so are octopuses, squids, and slugs. mollusks live on land and in freshwater.

they both go up but then go back down. they both end lower than they started. lastly, they both are competitive/the second on.
