People have two copies of most genes, one copy inherited from each parent. In some cases, however, the number of copies variesâmeaning that a person can be born with one, three, or more copies of particular genes. Less commonly, one or more genes may be entirely missing.ften, gene mutations that could cause a genetic disorder are repaired by certain enzymes before the gene is expressed and an altered protein is produced. Each cell has a number of pathways through which enzymes recognize and repair mistakes in DNA.

The Malbec grape is a thin-skinned grape and needs more sun and heat than either Cabernet Sauvignon or Merlot to mature. It ripens mid-season and can bring very deep color, ample tannin, and a particular plum-like flavor component to add complexity to claret blends.he Malbec of the Cahors region is much more tannic with more phenolic compounds that contribute to its dark color. Oz Clarke describes Cahors' Malbec as dark purple in color with aromas of damsons, tobacco, garlic, and raisin.
