RNA-seq

RNA-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.
Before the discovery of RNA-seq, microarray-based methods and Sanger sequencing were used for transcriptome analysis. However, while...

DNA Agarose Gel Electrophoresis

DNA Agarose Gel Electrophoresis

Agarose gel electrophoresis is a laboratory technique commonly used to separate DNA fragments by size. However, it can also be used to isolate and purify DNA fragments using a gel extraction protocol.
Gel extraction follows five major steps: running gel electrophoresis to separate fragments, isolating the individual bands, extracting DNA from those bands, and removing the dye and salts from the extracted mixture to obtain pure DNA.
In cloning experiments, both the insert and vector DNA...

Main Methods:

Developed a novel algorithm named GeLuster.
Tested GeLuster on simulated and real-world datasets, including Nanopore and PacBio data.
Compared GeLuster's performance against existing methods in terms of speed, memory consumption, and accuracy.

Main Results:

GeLuster demonstrated superior performance on both simulated and real datasets.
On Nanopore data, GeLuster was 2.9-17.5 times faster than the next best method, using less than one-seventh of the memory.
Achieved higher clustering accuracy compared to existing algorithms.
Similar performance improvements were observed on PacBio data.

Conclusions:

GeLuster offers a significant improvement in efficiency and accuracy for long-read RNA sequencing data.
