Examples of constitutive genes
WebSummary. Promoters are about 100-1000 base pairs long and are adjacent and typically upstream (5’) of the sense or coding strand of the transcribed gene. The coding strand is the DNA strand that encodes codons and whose sequence corresponds to the mRNA transcript produced. The antisense strand is referred to as the template strand or non ...

WebA constitutive gene is unregulated, which means that its expression level is relatively constant. In contrast, the expression of a regulated gene varies under different conditions. In bacteria, the regulation of genes often occurs at the level of transcription by combinations of regulatory proteins and small effector molecules. In addition, gene expression can be … WebOct 9, 2024 · Those that are always expressed are termed as constitutive genes, for example genes for ribosomes.
