Resumen
Los ARN no codificantes (ARNnc) son abundantes en los eucariotas y juegan un papel crucial en la organización y regulación del genoma. La investigación de estas transcripciones funcionales es vital para comprender los complejos procesos genómicos.
Área de la Ciencia:
- La genómica es la genómica.
- Biología Molecular Biología Molecular
- La bioinformática es la bioinformática.
Sus antecedentes:
- Los genomas de los eucariotas contienen una gran cantidad de transcripciones.
- Muchas de estas transcripciones carecen de potencial de codificación de proteínas, tradicionalmente denominadas ARN no codificantes (ARNnc).
- La importancia funcional de los ncRNAs ha sido históricamente subestimada.

Overview
DNA as a Genetic Template
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...
DNA-only Transposons
DNA-only transposons are called autonomous transposons since they code for the enzyme transposase that is required for the transposition mechanism. Insertion of transposons can alter gene functions in multiple ways. They can mutate the gene, alter gene expression by introducing a novel promoter or insulator sequence, introduce new splice sites, and change the mRNA transcripts produced, or remodel chromatin structure.
The donor site from where the transposon is excised is either degraded or...

The DNA Helix
Deoxyribonucleic acid, or DNA, is the genetic material responsible for passing traits from generation to generation in all organisms and most viruses. DNA is composed of two strands of nucleotides that wind around each other to form a spring-like structure called a double helix. However, the double helix is not perfectly symmetrical. Instead, there are regularly occurring grooves in the structure. The major groove occurs where the sugar-phosphate backbones are relatively far apart. This space...
