How Genes are Expressed

Gene expression involves converting DNA information into functional proteins. It starts with transcription in the nucleus, where DNA is transcribed into RNA. The RNA is processed into mRNA, which travels to ribosomes in the cytoplasm. Here, translation occurs, assembling proteins by matching tRNA anticodons with mRNA codons, linking amino acids into a chain. The process completes when the protein is fully formed.
