Question

The promoter region is the portion of dna to which rna polymerase binds at the start of transcription.

Answer 1

The given statement holds True.

What is Transcription?

The act of transcribing a section of DNA into RNA is called transcription. Messenger RNA is the term for DNA segments that have been translated into RNA molecules that can encode proteins (mRNA). Non-coding RNAs are formed when additional DNA segments are transcribed into RNA molecules (ncRNAs).

In a given tissue, the amount of mRNA is more than 10 times more than the amount of ncRNA when averaged across different cell types (though in particular single cell types ncRNAs may exceed mRNAs). Less than 2% of the human genome can be transcribed into mRNA, but at least 80% of mammalian genomic DNA can be actively transcribed (in one or more types of cells), with the majority of this 80% thought to be mRNA, the general preponderance of mRNA in cells is valid despite this.
