DNA transcription and mRNA processing (video) | 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 introns, resulting in mature mRNA, which …

Translation (mRNA to protein) (video) | Khan Academy
Translation occurs in ribosomes, which are cellular structures made of proteins and ribosomal RNA (rRNA). Here, mRNA is converted into amino acid sequences, forming polypeptides. Transfer RNA (tRNA) carries amino acids and matches them with mRNA codons, allowing ribosomes to synthesize proteins.
Khan Academy
Translation is the process where mRNA is converted into proteins by ribosomes.

Prokaryotes and eukaryotes review - Khan Academy
For example, most protists are single-celled eukaryotes! Even though prokaryotes do not have a nucleus, they DO contain genetic information. Prokaryotes generally have single circular chromosomes where they store their genetic information.
Khan Academy
DNA transcription and RNA translation are key processes in converting genetic information into proteins. Amino acid translation tables help determine the resulting amino acids, while point mutations and frameshift mutations can impact protein synthesis.
