Overview of transcription - Khan Academy
Transcription is the first step in gene expression, in which information from a gene is used to construct a functional product such as a protein. The goal of transcription is to make a RNA copy of a gene's …
Stages of transcription - Khan Academy
An in-depth looks at how transcription works. Initiation (promoters), elongation, and termination.
Transcription and mRNA processing - Khan Academy
Transcription is when we take the information encoded in the gene in DNA and encode essentially that same information in mRNA. So transcription we are going from DNA to messenger RNA, and we're …
Les étapes de la transcription (leçon) | Khan Academy
La transcription est une étape essentielle de l'exploitation des informations génétiques de notre ADN pour fabriquer des protéines. Les protéines sont les molécules clés qui structurent les cellules et les …
Eukaryotic pre-mRNA processing | RNA splicing (article) - Khan Academy
The molecule that's directly made by transcription in one of your (eukaryotic) cells is called a pre-mRNA, reflecting that it needs to go through a few more steps to become an actual messenger RNA (mRNA).
DNA replication and RNA transcription and translation
Replication creates identical DNA strands, while transcription converts DNA into messenger RNA (mRNA). Translation then decodes mRNA into amino acids, forming proteins essential for life functions.
Regulation of transcription (video) | Khan Academy
Now a few notes about the differences between prokaryotes and eukaryotes when it comes to transcriptional regulation. In prokaryotes, the regulation of transcription is really needed for the cell to …
Transcription and mRNA processing (article) | Khan Academy
During transcription, a gene's nucleotide sequence (DNA) is copied to form messenger RNA (mRNA), which serves as a temporary blueprint. In eukaryotes, this occurs in the nucleus.
Resumen de la transcripción (artículo) | Khan Academy
Transcription is the DNA-directed synthesis of RNA: A closer look (La transcricpción es la síntesis de ARN dirigida por el ADN: una revisión más profunda). En
Types of RNA (article) | Khan Academy
This article summarizes the different types of RNA, including more well-known RNA like tRNA and ribosomal RNA, and less-known RNA like siRNA that also contribute to cell function.
