Ribosome Profiling02:24

Ribosome Profiling

3.9K
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...

RNA-seq

11.1K
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 Microarrays

19.7K
Microarrays are high-throughput and relatively inexpensive assays that can be automated to analyze large quantities of data at a time. They are used in genome-wide studies to compare gene or protein expression under two varied conditions, such as healthy and diseased states. Microarrays consist of glass or silica slides on which probe molecules are covalently attached through surface functionalization. Most commonly, the slides are prepared through the chemisorption of silanes to silica...

Synthetic Disvision of Polynomials

36
Synthetic division is an efficient algorithmic approach for dividing a polynomial by a linear binomial of the form x - c, where c is a real number. This method is helpful due to its streamlined process, which avoids the more cumbersome steps involved in the traditional long division of polynomials. It simplifies computation and serves as a practical tool for evaluating polynomials and identifying their factors.To perform synthetic division, one begins by listing the coefficients of the...

Area of Science:

  • Molecular Biology
  • Genomics
  • Bioinformatics

Background:

  • Quantifying genomic sequence patterns and their relationship to phenotype is crucial in molecular biology.
  • Existing methods may not fully capture complex sequence-phenotype interactions.

Purpose of the Study:

  • To introduce a multivariate tensor-based orthogonal polynomial approach for sequence analysis.
  • To map phenotypes onto sequence space and identify functional relationships.
  • To provide a computational tool for broader biological applications.

Main Methods:

  • A multivariate tensor-based orthogonal polynomial approach was employed.
  • The method characterizes nucleotides/amino acids and maps phenotypes onto sequence space.
  • Analysis was applied to small transcription activating RNAs, including covariance and regression analyses.

Main Results:

  • Covariance patterns showed strong correlations between nucleotides at sequence ends.
  • Phenotype projection onto sequence space did not reveal this pattern.
  • Second-order analysis identified potential intramolecular binding sites across the sequence.

Conclusions:

  • The proposed method effectively quantifies sequence-phenotype interactions at multiple levels.
  • It offers insights into potential intramolecular binding and functional relationships.
  • The approach is versatile and applicable to diverse biological systems, with an accompanying tool.
