Summary
The human transcriptome is surprisingly complex, revealing a vast universe of non-protein coding RNAs beyond genes. These RNAs are dynamically transcribed and can regulate genome activity, indicating more complexity than previously understood.
Area of Science:
- Genomics
- Molecular Biology
- Transcriptomics
Background:
- Understanding genome function requires characterizing transcribed RNA products.
- The transcriptome is unexpectedly complex, necessitating advanced technologies for comprehensive analysis.
- Genome sequencing projects have primarily focused on protein-coding genes.
Purpose of the Study:
- To explore the complexity of the transcriptome, including non-protein coding RNAs.
- To investigate the role and regulation of various RNA transcripts.
- To highlight the dynamic nature of RNA transcription and its impact on genome output.
Main Methods:
- Development of high-throughput technologies for capturing RNA transcripts.
- Large-scale generation and analysis of full-length complementary DNAs (cDNAs).
- Application of complementary experimental approaches to identify and validate RNA products.
Main Results:
- Discovery of a significant 'hidden transcriptional universe' of non-protein coding RNAs.
- Demonstration of dynamic transcription of diverse RNA types.
- Evidence that a subset of non-protein coding RNAs function as sense-antisense RNAs, influencing transcription.
Conclusions:
- The human transcriptome is far more complex than initially assumed, with a substantial proportion of non-protein coding RNAs.
- Non-protein coding RNAs play active roles in regulating genome transcription.
- Current understanding of the transcriptome remains incomplete, with ongoing discoveries revealing greater complexity.

02:24Ribosome Profiling
Ribosome profiling or ribo-sequencing is a deep sequencing technique that produces a snapshot of active translation in a cell. It selectively sequences the mRNAs protected by ribosomes to get an insight into a cell’s translation landscape at any given point in time.
Applications of ribosome profiling
Ribosome profiling has many applications, including in vivo monitoring of translation inside a particular organ or tissue type and quantifying new protein synthesis levels.

02:01pre-mRNA Processing
In eukaryotic cells, transcripts made by RNA polymerase are modified and processed before exiting the nucleus. Unprocessed RNA is called precursor mRNA or pre-mRNA to distinguish it from mature mRNA.
Once about 20-40 ribonucleotides have been joined together by RNA polymerase, a group of enzymes adds a “cap” to the 5’ end of the growing transcript. In this process, a 5’ phosphate is replaced by modified guanosine that has a methyl group attached to it (7-Methyl guanosine). This 5’ cap helps the...

03:36Genome Annotation and Assembly
The genome refers to all of the genetic material in an organism. It can range from a few million base pairs in microbial cells to several billion base pairs in many eukaryotic organisms. Genome assembly refers to the process of taking the DNA sequencing data and putting it all back together in a correct order to create a close representation of the original genome. This is followed by the identification of functional elements on the newly assembled genome, a process called genome annotation.
