What is dna upstream vs downstream?

DNA upstream and downstream refer to the directionality of genetic information on the DNA molecule. Upstream refers to the direction of the DNA sequence that is towards the 5' end of the DNA molecule or towards the gene's promoter region, while downstream refers to the direction that is towards the 3' end of the DNA molecule or towards the transcription terminator region. Upstream and downstream regions of a gene contain regulatory sequences, such as enhancers and silencers, that control gene expression and can influence the rate and timing of transcription. In summary, upstream and downstream DNA regions play important roles in regulating gene expression and providing genetic information for protein synthesis.
