Genome Annotation and Assembly03:36

Genome Annotation and Assembly

22.2K
The genome refers to all of the genetic material in an organism. It can range from a few million base pairs in microbial cells to several billion base pairs in many eukaryotic organisms. Genome assembly refers to the process of taking the DNA sequencing data and putting it all back together in a correct order to create a close representation of the original genome. This is followed by the identification of functional elements on the newly assembled genome, a process called genome annotation.

Polytene Chromosomes02:04

Polytene Chromosomes

11.4K
Polytene chromosomes are giant interphase chromosomes with several DNA strands placed side by side. They were discovered in the year 1881 by Balbiani in salivary glands, intestine, muscles, malpighian tubules, and hypoderm of larvae Chironomus plumosus. Hence, these are also called "Salivary gland chromosomes." These are found in insects of the order Diptera and Collembola; in certain organs of mammals; and synergids, antipodes of flowering plants. Polytene chromosomes are also...

Spindle Assembly02:50

Spindle Assembly

4.5K
Spindle assembly occurs through three, often coexisting, pathways – the centrosome-mediated pathway, the chromatin-mediated pathway, and the microtubule-mediated pathway – collectively contributing to form a robust spindle apparatus.
In most cells, centrosomes are the primary microtubule nucleation centers. In the centrosome-mediated pathway, the G2-prophase transition triggers centrosome maturation and increased microtubule nucleation. Progressive nucleation results in a...

Genomic DNA in Eukaryotes

54.6K
Eukaryotes have large genomes compared to prokaryotes. To fit their genomes into a cell, eukaryotic DNA is packaged extraordinarily tightly inside the nucleus. To achieve this, DNA is tightly wound around proteins called histones, which are packaged into nucleosomes that are joined by linker DNA and coil into chromatin fibers. Additional fibrous proteins further compact the chromatin, which is recognizable as chromosomes during certain phases of cell division.

Area of Science:

  • Genomics
  • Bioinformatics
  • Computational Biology

Background:

  • The increasing number of sequenced diploid genomes highlights a gap in current assembly tools.
  • Highly polymorphic (HP) diploid genomes present unique challenges for accurate genome assembly.
  • Existing assembly methods, often developed pre-next-generation sequencing (NGS), are inadequate for HP genomes.

Purpose of the Study:

  • To address the limitations of current tools for assembling highly polymorphic diploid genomes.
  • To introduce a novel assembler specifically designed for the complexities of HP diploid genomes using NGS data.

Main Methods:

  • Development of dipSPAdes, a de Bruijn graph-based assembler.
  • Adaptation of assembly algorithms to handle the high polymorphism characteristic of HP genomes.
  • Evaluation of dipSPAdes against existing state-of-the-art assemblers.

Main Results:

  • dipSPAdes is the first de Bruijn graph assembler developed for highly polymorphic diploid genomes.
  • The new assembler demonstrates significant improvements over current state-of-the-art methods.
  • Successfully addresses the shortage of specialized tools for HP genome assembly from NGS data.

Conclusions:

  • dipSPAdes represents a significant advancement in the field of genome assembly for highly polymorphic diploid organisms.
  • The development of dipSPAdes fills a critical need for specialized tools in genomic research.
  • Facilitates more accurate and comprehensive analysis of HP diploid genomes using NGS data.
