Role of small noncoding rna in gene regulation in mammals
Answers
Answer:
non-coding RNA (ncRNA) is an RNA molecule that is not translated into a protein. The DNA sequence from which a functional non-coding RNA is transcribed is often called an RNA gene. Abundant and functionally important types of non-coding RNAs include transfer RNAs (tRNAs) and ribosomal RNAs (rRNAs), as well as small RNAs such as microRNAs, siRNAs, piRNAs, snoRNAs, snRNAs, exRNAs, scaRNAs and the long ncRNAs such as Xist and HOTAIR.
The number of non-coding RNAs within the human genome is unknown; however, recent transcriptomic and bioinformatic studies suggest that there are thousands of them.[1][2][3][4][5][6] Many of the newly identified ncRNAs have not been validated for their function.[7] It is also likely that many ncRNAs are non functional (sometimes referred to as junk RNA), and are the product of spurious transcription
