RNA and protein synthesis review - Khan Academy
In eukaryotic cells, transcription occurs in the nucleus, and translation occurs at the ribosomes in the cytoplasm. In prokaryotic cells and bacterium, both transcription and translation happen in the …
Eukaryotic pre-mRNA processing | RNA splicing (article) - Khan Academy
In this article, we'll take a closer look at the cap, tail, and splicing modifications that eukaryotic RNA transcripts receive, seeing how they're carried out and why they are important for making sure we get …
Cellular organelles and structure (article) | Khan Academy
All cells have membranes (the building), DNA (the various blueprints), and ribosomes (the production line), and so are able to make proteins (the product - let’s say we’re making toys). This article will …
The genetic code & codon table (article) | Khan Academy
Decoding messages is also a key step in gene expression, in which information from a gene is read out to build a protein. In this article, we'll take a closer look at the genetic code, which allows DNA and …
Overview: Eukaryotic gene regulation (article) | Khan Academy
That is, we'll see how the expression of genes in eukaryotes (like us!) can be controlled at various stages, from the availability of DNA to the production of mRNAs to the translation and processing of …
Nucleic acids (article) | Khan Academy
While DNA stores genetic information, RNA is involved in protein synthesis and gene regulation, as well as storing genetic information in some viruses. DNA and RNA also have different structures; DNA's …

Endoplasmic reticulum and golgi apparatus - Khan Academy
It's divided into two parts: the ribosome-studded rough endoplasmic reticulum, where protein synthesis occurs, and the smooth endoplasmic reticulum, responsible for lipid synthesis and detoxification.
DNA replication (article) | Khan Academy
DNA is made out of protein, and although enzymes are also protein, they only serve to speed up the reaction and are going to emerge out of the reaction unchanged.
