Prokaryotic Gene Regulation
Eukaryotic Gene Regulation & Development
Homeotic, Homeobox, and Hox Genes
100

DNA-binding proteins in prokaryotes regulate genes by controlling this specific process.

Transcription

100

This specific "box" is a feature found in a typical eukaryotic gene.

TATA box

100

These genes regulate organ development

Homeotic genes

200

This specific operon is turned off by regulatory proteins that bind to DNA and block transcription when lactose is absent.

Lac operon

200

These factors control the expression of eukaryotic genes by binding to DNA sequences in the regulatory regions.

Transcription factors

200

These genes determine the identities of each body segment

Hox genes

300

When the lac repressor binds to this specific region, RNA polymerase is blocked from reaching the lac genes.

O region

300

In eukaryotes, this structural outcome and differentiation are made possible by complex gene regulation.

Cell specialization

300

These genes code for transcription factors

Homeobox genes

400

To turn on the operon, lactose diffuses into the cell and attaches directly to this structure.

Lac repressor

400

Regulating gene expression plays a vital role in shaping how this specific type of organism develops.
