Multi-species Conserved Sequences02:51

Multi-species Conserved Sequences

4.6K
Next-generation sequencing technologies have created large genomic databases of a variety of animals and plants. Ever since the human genome project was completed, scientists studied the genome of primates, mammals, and other phylogenetically distant living beings. Such large-scale  studies have provided new insights into the evolutionary relationship between organisms.
Although the genome of each species varies greatly from each other, a few sequences are highly conserved. Such conserved...

RNA-seq03:21

RNA-seq

11.6K
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 Microarrays02:34

DNA Microarrays

20.5K
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...

Structure of a Gene01:30

Structure of a Gene

15.2K
A gene is the fundamental unit of heredity. Every individual has two copies of each gene, one inherited from each parent. Although most people contain the same genes, there is a small fraction that is slightly different amongst people. A gene with a small difference in its sequence of DNA bases forms different alleles, contributing to different phenotypes.
However, only 1% of the DNA is composed of genes that encode proteins; the rest, 99% is non-coding DNA. This non-coding DNA performs...

Gene Duplication and Divergence02:37

Gene Duplication and Divergence

7.7K
The seminal work of Ohno in 1970 popularized the idea of gene duplication and divergence. DNA sequence comparison studies reveal that a large portion of the genes in bacteria, archaebacteria, and eukaryotes was  generated by gene duplication and divergence, indicating its critical role in evolution.
The duplicated copies of the gene are called Paralogs. Paralogs with similar sequences and functions form a gene family. Across several species, a large number of gene families are...

Advancements in molecular biology have revolutionized the identification and characterization of bacteria, with multiple methods leveraging DNA sequencing for enhanced precision. As sequencing technologies improve and costs decline, these approaches are increasingly used in clinical, environmental, and evolutionary studies.Multilocus Sequence Typing (MLST) examines several housekeeping genes, essential chromosomal genes encoding cellular functions, to distinguish strains. Approximately...

Area of Science:

  • Molecular Biology
  • Genetics
  • Bioinformatics

Background:

  • Multi-dimensional gene analysis offers deep insights but struggles with complex networks and similar sequences.
  • Existing methods often compromise accuracy due to reaction perturbations and limited discrimination of analogous sequences.

Purpose of the Study:

  • To develop a sequence-oriented enrichment method for precise gene locus identification.
  • To overcome limitations in differentiating analogous sequences and enhance multi-dimensional gene analysis.

Main Methods:

  • Theoretically derived nucleic acid probes with energetically favorable structures were designed for specific gene loci.
  • Universal probes were created for conserved loci to prevent cross-reactions, alongside competitive probes to differentiate target enrichment from analogues.
  • The method utilizes gene locus guidance for sequence enrichment and combinatorial signaling.

Main Results:

  • The developed method achieves locus-specific enrichment without crosstalk between concurrent reactions.
  • Variant loci are synchronously identified with nucleotide-level resolution by differentiating reaction equilibrium and kinetics.
  • The system generates unique codes for multidimensional and precise gene decoding.

Conclusions:

  • This locus-guided, sequence-oriented enrichment method provides a robust platform for accurate gene analysis.
  • The approach significantly improves the discrimination of analogous sequences and variant loci identification.
  • It enables access to multidimensional and precise genetic information, advancing gene decoding capabilities.
