Answer :
Non-protein-coding DNA that is transcribed into several kinds of small RNAs with biological function is the correct answer.
Numerous protein-coding and non-protein coding sequences can be found in the human genome. The sequences that can be translated into protein sequences are known as protein-coding sequences.
Although it was anticipated that these coding sequences would be larger when the genome was sequenced, the sequences turned out to be smaller. This demonstrates that non-coding sequences make up the majority of the genome.
These non-coding sequences are significant because, while they cannot be translated into proteins, they can be translated into a variety of RNA molecules, including regulatory RNA, ribosomal RNA, and others, through transcription.
