Genome Annotation and Assembly03:36

Genome Annotation and Assembly

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.
Proteomics01:33

Proteomics

A proteome is the entire set of proteins that a cell type produces. We can study proteomes using the knowledge of genomes because genes code for mRNAs, and the mRNAs encode proteins. Although mRNA analysis is a step in the right direction, not all mRNAs are translated into proteins.
Proteomics is the study of proteomes' function. It involves the large-scale systematic study of the proteome to denote the protein complement expressed by a genome. Scientist Mark Wilkins coined the term proteomics...
Characteristics of Life01:23

Characteristics of Life

Biology is a natural science that studies life and living organisms, including their structure, function, development, interactions, evolution, distribution, and taxonomy. The field's scope is extensive and divided into several specialized disciplines, such as anatomy, physiology, ethology, genetics, and many more. All living things share a few key traits, including cellular organization, heritable genetic material and the ability to adapt/evolve, metabolism to regulate energy needs, the...
Synthetic Biology02:55

Synthetic Biology

Synthetic biology is an interdisciplinary science that involves using principles from disciplines such as engineering, molecular biology, cell biology, and systems biology. It involves remodeling existing organisms from nature or constructing completely new synthetic organisms for applications such as protein or enzyme production, bioremediation, value-added macromolecule production, and the addition of desirable traits to crops, to name a few.

Tagging and Fusion Proteins01:24

Tagging and Fusion Proteins

Proteins are involved in several cellular processes and biochemical reactions. Analyzing a specific protein of interest requires it to be isolated from the other proteins in the cell. This is achieved by overexpressing the specific gene in a suitable host to produce large quantities of the target protein. A tag or label is recombined with the gene to produce a fusion protein containing the target protein and the tag. The tags on these fusion proteins can then be used for easy detection and...
Proteins: From Genes to Degradation02:11

Proteins: From Genes to Degradation

Within a biological system, the DNA encodes the RNA, and the nucleotide sequence in the RNA further defines the amino acid sequence in the protein. This is referred to as “The Central Dogma of Molecular Biology” - a term coined by Francis Crick.  Central dogma is a firm principle in biology that defines the flow of genetic information within any life form. The two fundamental steps in central dogma are - transcription and translation.
Transcription is the synthesis of RNA molecules by RNA...

Area of Science:

  • Biomedical informatics
  • Ontology engineering

Background:

  • Biomedical processes are crucial for understanding organism function and are represented in ontologies like GO.
  • Representing process attributes (e.g., rates, regularities) is challenging and has led to inconsistent solutions in bio-ontologies.

Purpose of the Study:

  • To present a design pattern for representing process attributes compatible with upper ontology frameworks.
  • To address the contentious issue of attribute representation in bio-ontologies.
  • To improve interoperability and logical consistency in biomedical domain ontologies.

Main Methods:

  • Developed a design pattern based on how repeated process parts constitute an overall process.
  • Applied the pattern to model and classify normal/abnormal heart beating rates and patterns.
  • Ensured entities with full logical definitions are not treated as primitives.

Main Results:

  • Presented a compatible design pattern for process attributes within upper ontology frameworks (BFO, BioTop).
  • Successfully modeled and classified heart beating processes based on rates and patterns.
  • Provided full definitions for process attributes across increasing domain complexity.

Conclusions:

  • Logical definition of process attributes is feasible, though limited by Description Logic (DL) expressivity.
  • The creation of primitives remains necessary in some cases.
  • Formal upper-ontology frameworks can ensure consistency, interoperability, and clarity in bio-ontologies.
