ANTONII [103]

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.

How does cell division differ in prokaryotes and eukaryotes?
notsponge [240]
KELPEL!!!

Okay, so prokaryotes cell division is different from eukaryotes because the prokaryotes cells are simpler and are smaller if I'm correct.
Eukaryotes on the other hand have more complex cells, and it takes longer for the cells to divide and multiply because of this.

Hope this helps!
