Hox Genes

What controls differentiation to determine an organism's body plan?

• lac operon

• protein complex

• polymerase

• hox genes

These type of genes tell our cells where to place various body structures. A mutation in one of these genes can cause an organism to look completely different.

• HOX genes

• Pseudogenes

• Nuclear genes

• Ribosomal genes

Hox genes determine an animal’s

• basic body plan.

• size.

• skin color.

• eye color.

In flies, the group of homeobox genes that determines the identities of each segment of a fly's body is the group known as

• silencing complexes

• promoters

• operators

• Hox genes
