Question

Where does RNA polymerase attach to DNA?

Answer 1

Enzymes that convert DNA to RNA are known as RNA polymerases. RNA polymerase uses a DNA template to create a new RNA molecule through base pairing. For example, RNA polymerase will add a C to the new, growing RNA strand if the DNA template contains a G.

Complete answer:
The RNA polymerase binds to a region known as the promoter on the DNA of a gene to begin transcribing it. This area denotes the polymerase, which will sit down' on the DNA and begin transcribing.

RNA polymerase is important because it performs transcription, which is the process of transcribing DNA (deoxyribonucleic acid, or DNA) into RNA (ribonucleic acid, a similar but more short-lived molecule).

Transcription is a crucial step in converting the information from our DNA's genes into proteins. Proteins are the essential molecules that give cells their shape and allow them to function. Because no new RNAs—and consequently no new proteins—can be generated when transcription is blocked with the mushroom toxin, it causes liver failure and death.

Cells readout, or express, the genetic instructions in their genes through transcription and translation. Because a single gene may produce many identical RNA copies, and each RNA molecule can direct the creation of many similar protein molecules, cells can swiftly create enormous amounts of protein when needed. However, each gene can be transcribed and translated with varying degrees of effectiveness, allowing the cell to produce large amounts of some proteins while producing little amounts of others. The most obvious way for a cell to adjust the expression of each of its genes according to the needs of the moment is to control the creation of its RNA.

A cell's initial step in reading out a required component of its genetic instructions is to convert a specific portion of its DNA nucleotide sequence—a gene—into an RNA nucleotide sequence. Although the information in RNA is replicated into a different chemical form, it is nevertheless written in the same language as DNA—the language of nucleotide sequences. As a result, the name transcription was coined.

The correct answer is Promoter.

Note: The process by which a cell creates an RNA copy of a portion of DNA in biology. The genetic information required to build proteins in a cell is carried by this RNA copy, known as messenger RNA (mRNA). It transports information from the cell's nucleus to the cytoplasm, where proteins are produced.
