Non-coding Regions

Definition

These are sections of DNA that do not contain the information to make proteins. They were once thought to be "junk DNA," but we now know they play important roles in regulating gene expression.

Introns:

These are non-coding regions within genes. They're transcribed into RNA but removed before translation into protein.

Promoters:

These are specific non-coding regions where RNA polymerase binds to start transcription.

Regulatory Sequences:

These non-coding regions control the rate and timing of gene expression.
