Resumen
La arquitectura del genoma está formada por su función, con estructuras de cromatina que modulan la actividad. Esta auto-organización explica diversas estructuras nucleares y características genómicas conservadas como la plasticidad y la robustez.
Área de la Ciencia:
- La genómica
- Biología molecular
- La biofísica
Sus antecedentes:
- Los genomas poseen intrincadas estructuras tridimensionales.
- Comprender la organización del genoma es crucial para descifrar la regulación genética y la función celular.
Objetivo del estudio:
- Para aclarar los principios fundamentales que rigen la organización del genoma.
- Explorar la relación entre la función del genoma y la arquitectura.
- Comprender el papel de la estructura de la cromatina en la modulación de la actividad del genoma.
Principales métodos:
- Integración de enfoques genéticos, bioquímicos, biofísicos y biológicos de las células.
- Análisis de las características estructurales de la cromatina y su impacto en la actividad del genoma.
- Investigación de los principios de autoorganización en la arquitectura nuclear.
Principales resultados:
- La función del genoma es un impulsor primario de la arquitectura del genoma.
- Las estructuras de cromatina actúan como moduladores, no determinantes absolutos, de la actividad del genoma.
- Los principios de autoorganización explican el surgimiento de las características de la cromatina y la diversidad de la arquitectura nuclear.
Conclusiones:
- La interacción de la función y la estructura impulsa la organización del genoma.
- La arquitectura nuclear exhibe diversidad y heterogeneidad en todos los tipos de células y tejidos.
- Las características genómicas conservadas como la plasticidad y la robustez surgen de estos principios organizativos.

DNA as a Genetic Template
25.8K
Two structural features of the DNA molecule provide a basis for the mechanisms of heredity: the four nucleotide bases and its double-stranded nature. The Watson-Crick model of double-helical DNA structure, proposed in 1952, drew heavily upon the X-ray crystallography work of researchers Rosalind Franklin and Maurice Wilkins. Watson, Crick, and Wilkins jointly received the Nobel Prize in Physiology or Medicine for their work in 1962. Franklin was, controversially, excluded from the prize for...

The Nucleosome
3.4K
Human DNA is almost two meters long. However, it is compressed inside a tiny nucleus measuring only a few microns in diameter. To make this degree of compaction possible, DNA is organized into several sequential levels so that it can fit into such a tiny space. The most compact form of DNA is a chromosome that can be seen under a microscope in a dividing cell.
In a chromosome, DNA is wound twice around a protein complex called a histone octamer core, which consists of 8 histone proteins. This...

DNA in a human cell is almost 2m long and it is packed inside a tiny nucleus that is only a few microns in diameter. The level of compaction of DNA inside the nucleus is astonishing. It is organized into several sequentially higher levels of compaction to fit into such a tiny space.

Genome Annotation and Assembly
20.1K
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.
