WebThe instructions in a gene (written in the language of DNA nucleotides) are transcribed into a portable gene, called an mRNA transcript. These mRNA transcripts escape the nucleus … WebA silencer is a sequence-specific element that induces a negative effect on the transcription of its particular gene. There are many positions in which a silencer element can be located in DNA. The most common position is found upstream of the target gene where it can help repress the transcription of the gene. [4]
