Selection and Biotechnology: the best of both worlds
... The previous section indicates that one of the main challenges for selection on a QTL is that it reduces selection on polygenes and, unless selection on the QTL is properly balanced against lost response in polygenes, QTL selection can be detrimental in the long-term and suboptimal in the short term ...

LESSON 1.3 WORKBOOK What do we know about how cancer is caused?
... As our understanding of cancer as a disease has evolved we have increasingly turned our attention to questions of what causes cancer in the first place. This lesson shows how three competing theories about the cause of cancer - infectious agents, environmental toxins, and genetics were reconciled. H ...

... Genes can be as short as 1000 base pairs or as long as several hundred thousand base pairs. It can even be carried by more than one chromosome. The estimate for the number of genes in humans has decreased as our knowledge has increased. As of 2001, humans are thought to have between 30,000 and 40,00 ...

How genetic mistakes cause short telomere diseases

DNA actually has two side-by-side strands, twisted to form the well-known double helix structure discovered by Watson and Crick. The strands are not identical; instead, they are complementary to each other. The rela ...
