1. Fill in the blanks using the following words (or their plural forms): gene, protein, trans-, cis-, enhancer, Hox, homeobox, homeotic. Some words may be used more than once or not at all. You must use the word homeobox.

Transcription factor _______ encode a type of _______ called a transcription factor. These _______ are a type of _______ regulatory element and function by binding to _______ regulatory elements, such as _______ , of other genes. Hox genes encode transcription factor ________, which contain a ________domain that binds to DNA. Hox mutations are often ________.

Explanation / Answer

Transcription factor genes encode a type of homeotic called a transcription factor. These proteins are a type of cis- regulatory element and function by binding to enhancer regulatory elements, such as Homeobox, of other genes. Hox genes encode transcription factor Hox, which contain a Homeobox domain that binds to DNA. Hox mutations are often Homeotic.
