Genetics of Speciation02:16

Genetics of Speciation

21.0K
Speciation is the evolutionary process resulting in the formation of new, distinct species—groups of reproductively isolated populations.

lncRNA - Long Non-coding RNAs

9.9K
In humans, more than 80% of the genome gets transcribed. However, only around 2% of the genome codes for proteins. The remaining part produces non-coding RNAs which includes ribosomal RNAs, transfer RNAs, telomerase RNAs, and regulatory RNAs, among other types. A large number of regulatory non-coding RNAs have been classified into two groups depending upon their length – small non-coding RNAs, such as microRNA, which are less than 200 nucleotides in length, and long non-coding RNA...

The Uncertainty Principle04:08

The Uncertainty Principle

31.7K
Werner Heisenberg considered the limits of how accurately one can measure properties of an electron or other microscopic particles. He determined that there is a fundamental limit to how accurately one can measure both a particle’s position and its momentum simultaneously. The more accurate the measurement of the momentum of a particle is known, the less accurate the position at that time is known and vice versa. This is what is now called the Heisenberg uncertainty principle. He...

Hardy-Weinberg Principle01:49

Hardy-Weinberg Principle

76.2K
Diploid organisms have two alleles of each gene, one from each parent, in their somatic cells. Therefore, each individual contributes two alleles to the gene pool of the population. The gene pool of a population is the sum of every allele of all genes within that population and has some degree of variation. Genetic variation is typically expressed as a relative frequency, which is the percentage of the total population that has a given allele, genotype or phenotype.

The Pauli Exclusion Principle

The arrangement of electrons in the orbitals of an atom is called its electron configuration. We describe an electron configuration with a symbol that contains three pieces of information:

What is Population Genetics?01:25

What is Population Genetics?

64.6K
A population is composed of members of the same species that simultaneously live and interact in the same area. When individuals in a population breed, they pass down their genes to their offspring. Many of these genes are polymorphic, meaning that they occur in multiple variants. Such variations of a gene are referred to as alleles. The collective set of all the alleles within a population is known as the gene pool.

Área de la Ciencia:

  • Genómica
  • Biología de Sistemas
  • Bioinformática

Sus antecedentes:

  • La relación entre la secuencia del genoma y el fenotipo es compleja y no se comprende completamente en todas las escalas biológicas.
  • La comprensión actual a menudo se basa en la modelización mecanicista, careciendo de un principio formal unificador.

Objetivo del estudio:

  • Identificar un principio formal universal que rige la relación secuencia del genoma-fenotipo en todas las escalas moleculares, celulares, tisulares y de órganos.
  • Establecer un marco de primeros principios para relacionar el genotipo con el fenotipo y guiar el descubrimiento biológico mecanicista.

Principales métodos:

  • Representación de fenotipos y genomas como grafos.
  • Utilización de la preservación de la estructura como la única restricción para el mapeo de grafos.
  • Aplicación del principio para predecir asociaciones genéticas y analizar datos biológicos en todas las escalas.

Principales resultados:

  • Se identificó un principio único, la correspondencia estructural, como subyacente a la relación secuencia del genoma-fenotipo.
  • Este principio redescubre con éxito el código de aminoácidos sin conocimiento previo de la traducción.
  • El marco predice asociaciones establecidas en fenotipos celulares y tisulares e identifica reguladores de la expresión génica espacial en el cáncer.

Conclusiones:

  • La correspondencia estructural ofrece un marco unificador para conectar la secuencia del genoma con la estructura fenotípica en todas las escalas biológicas.
  • Este principio proporciona una herramienta poderosa para predecir asociaciones genéticas e impulsar el descubrimiento mecanicista en biología y medicina.
