Eukaryotic pre-mRNA processing | RNA splicing (article) - Khan Academy
Key points: When an RNA transcript is first made in a eukaryotic cell, it is considered a pre-mRNA and must be processed into a messenger RNA (mRNA). A 5' cap is added to the beginning of the RNA …

Transcription and mRNA processing - Khan Academy
In eukaryotic cells, DNA to mRNA transcription occurs within the nucleus, producing pre-mRNA. This pre-mRNA undergoes processing, including the addition of a 5' cap, a poly-A tail, and splicing out …
Transcription and mRNA processing (article) | Khan Academy
In eukaryotes, mRNA transcripts must be processed (modified) before they can be used to synthesize proteins at the ribosomes. This processing has two main components: protection and splicing.
Stages of translation (article) | Khan Academy
Translation involves “decoding” a messenger RNA (mRNA) and using its information to build a polypeptide, or chain of amino acids. For most purposes, a polypeptide is basically just a protein …

Translation (mRNA to protein) (video) | Khan Academy
Translation is the process whereby mRNA is converted into proteins by ribosomes. Translation occurs in ribosomes, which are cellular structures made of proteins and ribosomal RNA (rRNA). Here, mRNA …
