Witrynathe decoding of an mRNA message into a protein. RNA interference is a major mechanism of gene regulation in eukaryotes. Explain how RNA interference works. small pieces of RNA bind to the mRNA to trigger degradation / block translation, shutting down gene expression - another major way that eukaryotic cells regulate gene expression. WitrynaIn other healthy humans, lactase activity persists at a high level throughout adult life, enabling them to digest lactose as adults. This dominantly inherited genetic trait is known as lactase persistence. The distribution of these different lactase phenotypes in human populations is highly variable and is controlled by a polymorphic element ...
Solved Question 20 2 pts 1. Match the statements below to - Chegg
WitrynaLactase persistence—the ability of adults to digest the lactose in milk—varies widely in frequency across human populations. This trait represents an adaptation to the domestication of dairying animals and the subsequent consumption of their milk. Five variants are currently known to underlie this phenotype, which is monogenic in … Witryna[WELLS:] Britain on my father's side, Denmark, Holland on my mother's side. But kind of northern Europe. [SWALLOW:] Northern Europe, OK. [SWALLOW:] You can see first of all that most people in Europe are lactase persistent. [WELLS:] My family background makes sense. In only a few regions is a large majority of people lactase persistent. … chanbaek rated r
Genetics of lactase persistence and lactose intolerance
Witrynapersistence—the lactase-persistence allele. When natural selection favors a beneficial allele, such as the lactase- persistence allele (red band), that allele is more likely to … WitrynaLactase persistence, the ability to digest lactose and therefore to drink fresh milk after the nursing period, exemplifies the process of gene-culture coevolution. Most people … WitrynaExpert Answer. Question 20 2 pts 1.
