Answer:

Enzymes

Explanation:

The regulation of gene expression is the central dogma of life. It is a series or set of mechanisms in which genetic information in the DNA expresses in the form of RNA or protein. Cells give gene expression b different mechanisms as transcription, maturation of mRNA, and translation.

During these mechanisms, different gene-regulatory proteins are influenced. For example, a set of RNA polymerases that are proteins transcribe the DNA molecule during transcription. Transcription factors are also proteins that control the synthesis of proteins in the cell. These proteins are an enzyme that catalyse the gene regulation in the human cells.
