The amounts and types of mRNA molecules in a cell reflect the function ... DNA are typically located close to transcription promoter sites — and this plays an important part in gene expression.

LUTHOR HD 3’mRNA-seq libraries display comprehensive transcription profiles, enabling high-definition gene expression characterization from single eukaryotic cells, cell biopsies, or purified ...

That mRNA is read and translated at a cell's ribosome ... located downstream of a core promoter region and typically around a TATA box—a DNA sequence rich in thymine and adenine repeats.
