Summary
A small portion of the mammalian genome codes for proteins, but a large fraction is transcribed into non-coding RNAs. A recent study reveals that non-coding RNA transcription can activate nearby genes.
Area of Science:
- Genomics
- Molecular Biology
- Gene Regulation
Background:
- The mammalian genome contains a vast non-coding region, with a significant portion transcribed into various non-coding RNAs.
- The precise functions of many non-coding RNAs remain largely uncharacterized, despite their abundance.
Purpose of the Study:
- To investigate the functional role of non-coding RNA transcription.
- To determine if non-coding RNA transcription can influence the expression of neighboring genes.
Main Methods:
- Analysis of genomic data to identify non-coding RNA transcription events.
- Experimental validation of gene activation in response to non-coding RNA transcription.
Main Results:
- Identification of specific non-coding RNA transcripts.
- Demonstration that transcription of these non-coding RNAs leads to the activation of adjacent protein-coding genes.
Conclusions:
- Non-coding RNA transcription plays an active role in gene regulation.
- This mechanism provides a novel pathway for controlling gene expression in mammals.

01:20Types of RNA
Three main types of RNA are involved in protein synthesis: messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). These RNAs perform diverse functions and can be broadly classified as protein-coding or non-coding RNA. Non-coding RNAs play important roles in regulating gene expression in response to developmental and environmental changes. Non-coding RNAs in prokaryotes can be manipulated to develop more effective antibacterial drugs for human or animal use.

01:53Bacterial Transcription
RNA polymerase (RNAP) carries out DNA-dependent RNA synthesis in both bacteria and eukaryotes. Bacteria do not have a membrane-bound nucleus. So, transcription and translation occur simultaneously, on the same DNA template.
Transcription can be divided into three main stages, each involving distinct DNA sequences to guide the polymerase. These are:

02:39lncRNA - Long Non-coding RNAs
In humans, more than 80% of the genome gets transcribed. However, only around 2% of the genome codes for proteins. The remaining part produces non-coding RNAs which includes ribosomal RNAs, transfer RNAs, telomerase RNAs, and regulatory RNAs, among other types. A large number of regulatory non-coding RNAs have been classified into two groups depending upon their length – small non-coding RNAs, such as microRNA, which are less than 200 nucleotides in length, and long non-coding RNA (lncRNA)...
