6. Outline the ways that tr8n0)f ug6 clfnanscriptinsp7zn qk+ fwns*86lor s*.w3 on of DNA is regulated in cells.
参考答案: Proteins bind to specific DNA sequences to regulate transcription.
Specific DNA sequences involved in gene regulation are ‘enhancers’ and ‘promoters’.
Promoter sequences indicate where transcription begins.
Promoter sequence binds to proteins called transcription factors .
Enhancers are short DNA sequences that promote transcription of (target) genes.
Enhancers also bind to transcription factor proteins.
Transcription factors control the rate of transcription.
The proteins bound at the enhancer can come into contact with proteins attached to the promoter increasing the rate of transcription.
