RNA

Entity

RNA

Intermediate molecule between DNA and proteins.

It is a nucleic acid composed of ribonucleotides joined by phosphodiester bonds, generally single-stranded and containing uracil rather than thymine. Its molecules can adopt structures that determine informational, catalytic, and regulatory functions.

RNA participates in gene expression, protein synthesis, and regulation of numerous cellular processes. Its different classes include messenger, ribosomal, transfer, and regulatory RNAs.

The video places RNA between DNA and proteins in the central dogma postulated by Francis Crick, and explains that in transcription a single strand of messenger RNA is obtained from DNA, which is then read by ribosomes during translation to synthesize proteins.

  El segundo es el paso de la transcripción. Ahí se obtiene un solo RNA mensajero, es una sola cadena. Y lo último sería, a partir de ese mensaje que ya tenemos, traducir.

  este es transcrito a ARN mensajero, el cual es leído por los ribosomas para sintetizar proteínas.
