Structure of a Gene

12.4K
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...

Chromatin Structure Regulates pre-mRNA Processing

6.9K
In eukaryotic cells, nascent mRNA transcripts need to undergo many post-transcriptional modifications to reach the cell cytoplasm and translate into functional proteins. For a long time, transcription and pre-mRNA processing were considered two independent events that occur sequentially in the cell. However, it has now been well established that transcription and pre-mRNA processing are two simultaneous processes that are precisely regulated inside the cell.
The chromatin structure, especially...

lncRNA - Long Non-coding RNAs

8.5K
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...

RNA Structure

4.7K
The basic structure of RNA consists of a string of ribonucleotides attached by phosphodiester bonds. Although most RNA is single-stranded, it can form complex secondary and tertiary structures. Such structures play essential roles in the regulation of transcription and translation.
Different Types of RNA Have the Same Basic Structure
There are three main types of ribonucleic acid (RNA) involved in protein synthesis: messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). All three...

Área de la Ciencia:

  • La neurociencia
  • Biología molecular
  • La genética

Sus antecedentes:

  • La expresión génica está estrictamente regulada por varios factores, incluidos los ARN no codificantes.
  • La desregulación de genes específicos está vinculada a comportamientos complejos como los inducidos por las drogas y el estrés.

Objetivo del estudio:

  • Investigar el papel del ARN no codificante en el control de la expresión de un gen asociado con comportamientos inducidos por drogas y estrés.

Principales métodos:

  • Utilizó técnicas de biología molecular para identificar y caracterizar el ARN no codificante.
  • Se empleó la manipulación genética para evaluar el impacto del ARN no codificante en la expresión génica.
  • Resultados de comportamiento analizados en respuesta a estímulos de drogas y estrés.

Principales resultados:

  • Identificó un ARN no codificante específico que modula directamente la expresión de un gen clave.
  • Se demostró que la alteración de los niveles de ARN no codificantes afecta la expresión del gen, lo que influye en las respuestas conductuales.
  • Se observaron cambios significativos en los comportamientos inducidos por el fármaco y el estrés que se correlacionan con la actividad del ARN no codificante.

Conclusiones:

  • El ARN no codificante juega un papel crítico en la regulación de la expresión génica pertinente para el control del comportamiento.
  • Este mecanismo regulador es un objetivo potencial para comprender y tratar las afecciones relacionadas con la adicción a las drogas y las respuestas al estrés.
