| 21. | Individuals who expressed lactase-persistent phenotypes would have had a significant advantage in nutritional acquisition.
|
| 22. | The evolutionary processes driving the rapid spread of lactase persistence in some populations are not known.
|
| 23. | In most Europeans, however, the infant condition persists, and the lactase gene remains active.
|
| 24. | Presumably the changes regulate the activity of the lactase gene in some manner yet to be understood.
|
| 25. | Several milk products _ including the brand milk you mentioned, Lactaid _ are fortified with lactase.
|
| 26. | Like most other adult mammals, adult cats are lactose intolerant because of low or absent lactase.
|
| 27. | Four novel mutations in the lactase gene ( LCT ) underlying congenital lactase deficiency ( CLD ).
|
| 28. | Four novel mutations in the lactase gene ( LCT ) underlying congenital lactase deficiency ( CLD ).
|
| 29. | The overall reaction that lactase catalyzes is C 12 H 22 O 11 + H 2 O ?
|
| 30. | For those with lactose intolerance, taking digestive enzymes containing lactase when consuming dairy products often improves symptoms.
