Summary
Degradome sequencing, using 5'-rapid amplification of cDNA ends (5'-RACE) and next-generation sequencing (NGS), reveals RNA degradation patterns. This method identifies microRNA targets and aids RNA processing studies, especially in non-model organisms.
Area of Science:
- Molecular Biology
- Genomics
- Biotechnology
Background:
- RNA degradation is crucial for gene regulation.
- Understanding RNA processing mechanisms is essential for biological research.
- Degradome sequencing offers a powerful tool for studying RNA dynamics.
Purpose of the Study:
- To present an optimized protocol for degradome library construction.
- To enable the sequencing of degradome cDNA fragments using next-generation sequencing (NGS).
- To facilitate the identification of microRNA targets and study RNA processing.
Main Methods:
- Adaptation of the 5 apid amplification of cDNA ends (5 apid amplification of cDNA ends) technique.
- Construction of high-yield, high-quality degradome libraries.
- Utilizing short-read next-generation sequencing (NGS) for fragment analysis.
Main Results:
- Degradome profiles can validate predicted microRNA-mediated cleavage events.

02:11Proteins: From Genes to Degradation
Within a biological system, the DNA encodes the RNA, and the nucleotide sequence in the RNA further defines the amino acid sequence in the protein. This is referred to as “The Central Dogma of Molecular Biology” - a term coined by Francis Crick. Central dogma is a firm principle in biology that defines the flow of genetic information within any life form. The two fundamental steps in central dogma are - transcription and translation.

01:57Sanger Sequencing
DNA sequencing is a fundamental technique that is routinely used in the biological sciences. This method can be applied to a range of questions at different scales - from the sequencing of a cloned DNA fragment or the study of a mutation in a gene up to whole-genome sequencing. However, despite the widespread use of sequencing today, it was not until 1977 that Fredrick Sanger and his collaborators developed the chain-termination method to decode DNA sequences. It relies on the separation of a...
03:00Next-generation Sequencing
The first human genome sequencing project cost $2.7 billion and was declared complete in 2003, after 15 years of international cooperation and collaboration between several research teams and funding agencies. Today, with the advent of next-generation sequencing technologies, the cost and time of sequencing a human genome have dropped over 100 fold.
Next-Generation Sequencing Methods
Although all next-generation methods use different technologies, they all share a set of standard features.

03:21RNA-seq
RNA sequencing, or RNA-Seq, is a high-throughput sequencing technology used to study the transcriptome of a cell. Transcriptomics helps to interpret the functional elements of a genome and identify the molecular constituents of an organism. Additionally, it also helps in understanding the development of an organism and the occurrence of diseases.

01:05Maxam-Gilbert Sequencing
In the same year as the discovery of the Sanger sequencing method, another group of scientists, Allan Maxam and Walter Gilbert, demonstrated their chemical-cleavage method for DNA sequencing. The Maxam-Gilbert method relies on using different chemicals that can cleave the DNA sequence at specific sites, the separation of resulting DNA fragments of variable size using electrophoresis, and deciphering the DNA sequence from the resulting gel bands.
