The Eukaryotic Promoter Region02:40

The Eukaryotic Promoter Region

18.7K
The eukaryotic promoter region is a segment of DNA located upstream of a gene. It contains an RNA polymerase binding site, a transcription start site, and several cis-regulatory sequences.  The proximal promoter region is located in the vicinity of the gene and has cis-regulatory sequences and the core promoter. The core promoter is the binding site for RNA polymerase and is usually located between -35 and +35 nucleotides from the transcription start site. The distal promoter regions are...

The Nucleosome Core Particle02:10

The Nucleosome Core Particle

14.1K
Nucleosomes are the DNA-histone complex, where the DNA strand is wound around the histone core. The histone core is an octamer containing two copies of H2A, H2B, H3, and H4 histone proteins.
The paradox
Nucleosomes, paradoxically, perform two opposite functions simultaneously. On the one hand, their main responsibility is to protect the delicate DNA strands from physical damage and help achieve a higher compaction ratio. While on the other hand, they must allow polymerase enzymes to access DNA...

Conserved Binding Sites01:49

Conserved Binding Sites

5.1K
Many proteins’ biological role depends on their interactions with their ligands, small molecules that bind to specific locations on the protein known as ligand-binding sites. Ligand-binding sites are often conserved among homologous proteins as these sites are critical for protein function.
Binding sites are often located in large pockets, and if their location on a protein’s surface is unknown, it can be predicted using various approaches. The energetic method computationally...

What is Conservation Biology?

24.0K
Conservation biology is a scientific field that focuses on the preservation of biodiversity in order to protect ecosystems while meeting the needs of the human population. Humans require properly functioning ecosystems to maintain our supply of natural resources, including food, medicines, and building materials.

Conservation of Small Populations02:04

Conservation of Small Populations

16.7K
Small population sizes put a species at extreme risk of extinction due to a lack of variation, and a consequent decrease in adaptability. This weakens the chances of survival under pressures such as climate change, competition from other species, or new diseases. Large populations are more likely to survive pressures such as these, as such populations are more likely to harbor individuals that have genetic variants that are adaptive under new stresses. Small populations are much less...

Conservation of Protein Domains Over Different Proteins02:26

Conservation of Protein Domains Over Different Proteins

14.1K
Protein domains are small structurally independent units that are part of a single amino acid chain.  Although these domains are often structurally independent, they may rely on synergistic effects to perform their functions as part of a larger protein. Protein domains may be conserved within the same organism, as well as across different organisms.
A limited set of protein domains often duplicate and recombine during evolution. These domains can be organized in different combinations to...

Area of Science:

  • Genomics
  • Bioinformatics
  • Computational Biology

Background:

  • Most functional elements in noncoding DNA have a conserved core region.
  • Current *de novo* motif inference systems often overlook this conserved core concept.

Purpose of the Study:

  • To explore the utility of incorporating conserved core regions into comparative genomics for identifying functional elements in noncoding DNA.
  • To investigate the trade-offs between full motif conservation and core region conservation.

Main Methods:

  • Modified the scoring function of Genetic Algorithms for Motif Inference (GAMI).
  • Employed a comparative genomics approach to search for putative functional elements.
  • Analyzed conservation strength of full motifs versus core regions.

Main Results:

  • Demonstrated that incorporating conserved core region information is beneficial for motif inference.
  • Showed that considering the structure of transcription factor binding sites aids in identifying functional elements.
  • Quantified the trade-offs between full motif and core region conservation.

Conclusions:

  • Integrating conserved core region information into motif inference systems enhances the discovery of functional noncoding DNA elements.
  • Comparative genomics combined with core region analysis is a powerful strategy for identifying biologically relevant motifs.
  • Understanding transcription factor binding site structure is key to improving computational identification of functional elements.
