In molecular genetics, a repressor is a DNA-or RNA-binding protein that inhibits the expression of one or more genes by binding to the operator or associated silencers. A DNA-binding …

2025年1月25日 · A repressor, as related to genomics, is a protein that inhibits the expression of one or more genes. The repressor protein works by binding to the promoter region of the …

The meaning of REPRESSOR is one that represses; especially : a protein that is determined by a regulatory gene, binds to a genetic operator, and inhibits the initiation of transcription of …

A repressor is an RNA or DNA binding protein that prevents the expression of genes by attaching to the operator or related silencers. A repressor protein binding to the DNA prevents the RNA …

These changes may enhance or diminish a repressor's ability to bind DNA or interact with other proteins, thereby affecting which genes are expressed. This adaptability is crucial for …

2024年11月23日 · repressor: any protein that binds to DNA and thus regulates the expression of genes by decreasing the rate of transcription; activator: any chemical or agent which regulates …

A repressor is a type of protein that inhibits gene expression by binding to specific DNA sequences, preventing the transcription of genes into RNA. By doing so, repressors play a …
