Chromatin Packaging

22.1K
Each human somatic cell contains 6 billion base-pairs of DNA. Each base-pair is 0.34 nm long, which means that each diploid cell contains a staggering 2 meters of DNA. How is such a long DNA strand packed inside a nucleus measuring only 10 - 20 microns in diameter? 
The chromatin
In combination with specialized DNA binding protein called Histones, the DNA double helix forms a compact DNA: protein complex called chromatin. The chromatin itself is further compacted into higher-order...

Each human somatic cell contains 6 billion base pairs of DNA. Each base pair is 0.34 nm long, meaning each diploid cell contains a staggering 2 meters of DNA. This long DNA strand is packed inside a nucleus measuring only 10-20 microns in diameter with the help of specialized DNA-binding proteins called histones. Together they form a compact DNA-protein complex called chromatin. The chromatin is further compacted into higher-order structures. The highest level of compaction is achieved during...

Cis-regulatory Sequences

11.8K
Cis-regulatory sequences are short fragments of non-coding DNA that are present on the same chromosomes as the genes that they regulate. These fragments serve as binding sites for transcriptional regulators, proteins that are responsible for controlling gene transcription and differential gene expression across cell types in eukaryotes. Cis-regulatory sequences can be close to the gene of interest or thousands of bases away in the DNA sequence; however, those sequences that are further away are...

Area of Science:

  • Genomics
  • Bioinformatics
  • Molecular Biology

Background:

  • Accurate identification of DNA libraries in multiplexed sequencing is crucial.
  • Next-generation sequencing (NGS) relies on unique DNA barcodes for library differentiation.

Purpose of the Study:

  • To introduce DNABarcodeCompatibility, an R-package for designing single or dual-barcoding multiplex experiments.
  • To facilitate unambiguous DNA library identification and optimize barcode usage in NGS.
  • To reduce costs associated with library preparation kits.

Main Methods:

  • Development of an R-package, DNABarcodeCompatibility.
  • Implementation of user-defined constraints for barcode design (sequencer chemistry, minimal distance, nucleotide content).
  • Optimization of barcode frequency usage.
  • Creation of a user-friendly interface and a web application (Java and Shiny).

Main Results:

  • The R-package enables the design of multiplexed DNA barcode experiments with specified constraints.
  • It optimizes barcode frequency, aiding in demultiplexing and reducing kit expenses.
  • A web application is available to assist users with varying expertise levels.

Conclusions:

  • DNABarcodeCompatibility simplifies the design of multiplexed sequencing experiments.
  • The package enhances the accuracy of DNA library identification and promotes cost-effectiveness.
  • It bridges the gap between core facility expertise and user experimental requirements.
