Real Time RT-PCR02:57

Real Time RT-PCR

65.6K
Real-time reverse transcription-polymerase chain reaction, or Real-time RT-PCR, is an analytical tool used to determine the expression level of target genes. The method involves converting mRNA to complementary DNA with the help of an enzyme known as reverse transcriptase, followed by the PCR amplification of the cDNA. These two processes can be performed simultaneously in a single tube or separately as a two-step reaction.
The real-time quantification of the number of amplified products is...

RNA-seq

12.2K
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...

Ribosome Profiling02:24

Ribosome Profiling

4.2K
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.
The technique...

Background:

  • Understanding RNA kinetics is crucial for processes like co-transcriptional folding and riboswitch function.
  • Current methods for studying RNA out-of-equilibrium kinetics are computationally intensive and often produce redundant data, hindering a complete view of RNA dynamics.

Purpose of the Study:

  • To introduce RNANR, a novel set of algorithms for enhanced exploration of RNA kinetics landscapes at the secondary structure level.
  • To address the limitations of existing methods by reducing redundancy and improving the efficiency of sampling RNA conformations.

Main Methods:

  • RNANR utilizes locally optimal structures to focus sampling on key areas of the kinetic landscape.
  • The algorithms incorporate a novel non-redundant stochastic sampling strategy alongside exhaustive enumeration.
  • RNANR offers a diverse set of structural parameters for detailed analysis.

Main Results:

  • RNANR generates a higher number of unique RNA structures within a given timeframe compared to existing methods.
  • The algorithms facilitate a more in-depth exploration of RNA kinetics landscapes.
  • Tests on both real and random RNA sequences validate RNANR's effectiveness.

Conclusions:

  • RNANR provides a more efficient and comprehensive approach to studying RNA kinetics.
  • The reduction in sampling redundancy offers a clearer perspective on RNA dynamics and intermediate states.
  • RNANR enhances the ability to analyze RNA secondary structure kinetics.
