[ix-layer structure for genomics:A powerful conceptual framework that integrates research, test and treatment]
1Institute of Rheumatology, Tokyo Women's Medical University, Japan.
Summary
A new "Six-layer structure" framework integrates diverse genomic data from life to cells. This model aids in understanding genomic research, tests, and drug therapies, paving the way for new discoveries.
Area of Science:
- Genomics
- Bioinformatics
- Systems Biology
Context:
- Increasing availability of diverse genomic datasets across medical and biological research.
- Need for a unified approach to manage and interpret complex genomic information.
- Existing frameworks lack a hierarchical structure for integrating multi-scale genomic data.
Purpose:
- To propose a novel conceptual framework, the "Six-layer structure," for integrating genomic data.
- To establish a hierarchical model organizing genomic information from the organismal to the cellular level.
- To define consistent partial orders within each layer using genomic data, such as phylogenetic and pedigree trees.
Summary:
- The proposed "Six-layer structure" organizes genomic data into hierarchical layers: life, species, population, family, individual, and cell.
- Each layer's members are composed of members from the layer below, allowing for multi-scale data integration.
- Genomic data, including phylogenetic and pedigree trees, enable the definition of partial orders within and between layers.
Impact:
- Facilitates integrated explanations for diverse genomic research, diagnostic tests, and drug therapies.
- Provides a foundation for novel discoveries in genomics and the development of new tests and therapeutics.
- Enhances the interpretation and application of genomic data in personalized medicine and biological research.

Structure of a Gene

A gene is the fundamental unit of heredity. Every individual has two copies of each gene, one inherited from each parent. Although most people contain the same genes, there is a small fraction that is slightly different amongst people. A gene with a small difference in its sequence of DNA bases forms different alleles, contributing to different phenotypes.
However, only 1% of the DNA is composed of genes that encode proteins; the rest, 99% is non-coding DNA. This non-coding DNA performs...

Genomic DNA in Eukaryotes
53.9K
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.

Genomics

Genomics is the science of genomes: it is the study of all the genetic material of an organism. In humans, the genome consists of information carried in 23 pairs of chromosomes in the nucleus, as well as mitochondrial DNA. In genomics, both coding and non-coding DNA is sequenced and analyzed. Genomics allows a better understanding of all living things, their evolution, and their diversity. It has a myriad of uses: for example, to build phylogenetic trees, to improve productivity and...

Nucleic Acid Structure
10.1K
The pentose sugar in DNA is deoxyribose, while in RNA the pentose sugar is ribose. The difference between the sugars is the presence of the hydroxyl group on the ribose's second carbon and a hydrogen on the deoxyribose's second carbon. The phosphate residue attaches to the hydroxyl group of the 5′ carbon of one sugar and the hydroxyl group of the 3′ carbon of the sugar of the next nucleotide, which forms a 5′ to 3′ phosphodiester linkage.
