The Central Dogma01:20

The Central Dogma

The central dogma explains the flow of genetic information from DNA nucleotides to the amino acid sequence of proteins.
RNA is the Missing Link Between DNA and Proteins
In the early 1900s, scientists discovered that DNA stores all the information needed for cellular functions and that proteins perform most of these functions. However, the mechanisms of converting genetic information into functional proteins remained unknown for many years. Initially, it was believed that a single gene is...

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:

  • Cardiovascular Physiology
  • Systems Biology
  • Molecular Biology

Background:

  • Traditional studies focus on individual molecules, limiting understanding of complex biological systems.
  • Cardiovascular physiology research is evolving with integrated multi-omics technologies.

Purpose of the Study:

  • To present key observations on how systems biology is reshaping the understanding of the central dogma in biological systems.
  • To highlight the shift from studying isolated components to understanding integrated molecular networks.

Main Methods:

  • Integration of orthogonal data sets from genomics, proteomics, and metabolomics.
  • Analysis of biological data across multiple tiers: gene, RNA, protein, and metabolite networks.

Main Results:

  • Systems biology deemphasizes the unidirectional gene-to-protein information flow.
  • Identified the role of molecular modules over isolated proteins in cellular function.
  • Revealed emergent properties and the critical importance of biological networks.
  • Demonstrated a new dimensionality in studying biological systems.

Conclusions:

  • Systems biology provides a more holistic and integrated approach to understanding cardiovascular physiology.
  • This paradigm shift is crucial for comprehending disease mechanisms rooted in network reprogramming.
