Homeobox genes are regulatory genes that play a critical role in coordinating developmental patterns.
Which of the rows in the table below correctly describes the conservation, function, and typical mutation effects of homeobox genes?
| Sequence conservation | Protein product function | Result of mutation | |
|---|---|---|---|
| A | Highly conserved across kingdoms | Acts as a transcription factor | Can cause homeotic transformation |
| B | Highly conserved across kingdoms | Acts as a ribosomal protein | Has no phenotypic effect |
| C | Highly unique to individual species | Acts as a transcription factor | Can cause homeotic transformation |
| D | Highly unique to individual species | Works as a metabolic enzyme | Prevents synthesis of amino acids |
