www.baylor.edu. Baylor University (BU) is a private Baptist university in Waco, Texas. Chartered in 1845 by the last Congress of the Republic of Texas, it is the oldest continuously-operating university in Texas and one of the first educational institutions west of the Mississippi River in the United States.
The LCT gene provides instructions for making an enzyme called lactase. This enzyme helps to digest lactose, a sugar found in milk and other dairy products. Lactase is produced by cells that line the walls of the small intestine.olecular Location on chromosome 2: base pairs 135,787,844 to 135,837,179. The LCT gene is located on the long (q) arm of chromosome 2 at position 21. More precisely, the LCT gene is located from base pair 135,787,844 to base pair 135,837,179 on chromosome 2.
In addition, the lactase gene has a higher expression when Tâ13910 and Aâ22018 are present and a lower expression when Câ13910 and Gâ22018 are present. The position -13910 has an enhancer function on the lactase promoter (the promoter facilitates the transcription of the LCT gene).actase-persistent alleles vary in their geographic distributions. Within European and descendent populations, they are almost entirely correlated with the presence of the -13,910 C/T mutation of the lactase gene (LCT).
