In eukaryotes, much of the nuclear DNA does not code for polypeptides. There are, for example, non-coding multiple repeats of base sequences between genes. Even within a gene only some sequences, called exons, code for amino acid sequences. Within the gene, these exons are separated by one or more non-coding sequences, called introns. 3 Transcription Define the terms proteome, 3.4.2 DNA and protein synthesis 10.3 codon and transcription The genetic code can be reviewed Describe the role of mRNA The concept of the genome as the briefly from the previous lesson.
