lncRNA - Long Non-coding RNAs02:39

lncRNA - Long Non-coding RNAs

9.8K
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...

Nursing Code of Ethics01:29

Nursing Code of Ethics

4.3K
The Nursing Code of Ethics sets the ethical benchmark for the profession, and guides nurses in ethical analysis and decision making at the societal, organizational, and clinical levels. The code encompasses showing compassion and respect for the patient, their families, and communities in all circumstances while committing to providing patient-centered care. In addition, the code states that nurses must advocate for the patient by defending a cause or recommendation to protect their rights,...

Intrinsically Disordered Proteins

19.3K
Intrinsically disordered proteins are a group of proteins that do not fold into specific three-dimensional structures. Their structural flexibility allows them to complement ordered proteins to perform functions that are inaccessible to rigid structures. They are more common in eukaryotes than prokaryotes and may either be exclusively intrinsically disordered or hybrid proteins, consisting of a mix of ordered and disordered regions. The absence of a rigid structure in these proteins can be...

Transcription

155.8K
Overview
Transcription is the process of synthesizing RNA from a DNA sequence by RNA polymerase. It is the first step in producing a protein from a gene sequence. Additionally, many other proteins and regulatory sequences are involved in the proper synthesis of messenger RNA (mRNA). Regulation of transcription is responsible for the differentiation of all the different types of cells and often for the proper cellular response to environmental signals.
Transcription Can Produce Different Kinds...

Area of Science:

  • Bioinformatics
  • Computational Biology
  • Genomics

Background:

  • High-throughput sequencing generates vast amounts of data.
  • Classifying RNA transcripts as protein-coding or non-coding remains challenging, particularly for poorly annotated species.

Purpose of the Study:

  • To introduce an upgraded tool, the Coding-Non-Coding Identifying Tool (CNIT).
  • To provide a faster and more accurate method for evaluating the coding potential of RNA transcripts.

Main Methods:

  • Development of CNIT, an upgraded version of the original Coding-Non-Coding Index (CNCI).
  • Performance evaluation of CNIT against CNCI using various species, including human, mouse, zebrafish, fruit fly, worm, and Arabidopsis.
  • Assessment of CNIT's accuracy using Area Under the Curve (AUC) values across 11 animal and 27 plant species.

Main Results:

  • CNIT demonstrates significantly improved performance, running approximately 200 times faster than CNCI.
  • CNIT exhibits higher accuracy in classifying RNA transcripts across multiple species compared to CNCI.
  • CNIT achieves high accuracy for nearly all eukaryotic transcripts, as indicated by AUC values.

Conclusions:

  • CNIT offers a substantial advancement in the computational identification of coding and non-coding RNA transcripts.
  • The tool's speed and accuracy make it valuable for analyzing large-scale transcriptomic data.
  • A publicly accessible, mobile-friendly web server for CNIT is available for research use.
