Promoter | This sequence signals the start of the gene and serves as the binding site for the RNA polymerase. |
Operator | It’s the regulatory segment of DNA where repressors bind to control gene expression. |
Regulatory Gene | These genes produce repressor proteins that bind to the operator, controlling transcription. |
Structural Genes | This section contains the actual DNA code for the proteins that the gene is meant to produce. |
Introns | These are non-coding sequences within a gene that are removed in the RNA splicing process. |
Exons | These are coding sequences that remain in the mature mRNA after splicing. |
5′ Untranslated Region (5′ UTR) | It’s the portion of the gene at the beginning of the RNA molecule that will not be translated into protein. |
3′ Untranslated Region (3′ UTR) | It’s the final portion of the gene. It’s transcribed into RNA but does not code for protein. |
Termination sequence | This sequence signals the end of the gene. It stops transcription. |
