What is Conservation Biology?

24.3K
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 Populations

17.3K
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...

Cis-regulatory Sequences02:02

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...

Conserved Binding Sites

5.2K
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...

Conservation of Protein Domains Over Different Proteins02:26

Conservation of Protein Domains Over Different Proteins

14.5K
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...

Summary

Identifying regulatory elements in DNA is crucial for understanding gene regulation. The PhyloCon algorithm enhances motif finding by integrating phylogenetic conservation and gene co-regulation data.

Area of Science:

  • Molecular Biology
  • Computational Biology
  • Bioinformatics

Background:

  • Gene regulation is a complex process mediated by DNA regulatory elements, including transcription factor binding sites.
  • Identifying these regulatory elements is a key challenge, known as the motif finding problem.
  • Numerous computational algorithms have been developed to address motif finding over the past two decades.

Purpose of the Study:

  • To present protocols for obtaining, installing, and applying the PhyloCon program.
  • To discuss the PhyloCon algorithm's methodology for motif identification.
  • To guide users in interpreting the results generated by PhyloCon.

Main Methods:

  • PhyloCon utilizes phylogenetic conservation across species to identify conserved regulatory elements.
