'Rosie' a transgenic cow known to produce a type of milk which has all the following characteristics except
(a) Protein content of $2.4 \mathrm{gm} /$ litre
(b) Has human $\alpha$ -lactalbumin
(c) More balance diet than normal milk for babies
(d) Rich in cholesterol

Key Concepts

Milk Nutritional Composition

Milk nutritional composition encompasses the range and balance of proteins, fats, carbohydrates, vitamins, and minerals present in milk. Understanding these components is crucial when evaluating or comparing conventional milk to milk from transgenic animals, as genetic modifications can be aimed at enhancing the overall nutritional balance.

Protein Engineering in Milk Production

Protein engineering in the context of milk production refers to modifying or introducing specific genes to alter the types and quantities of proteins expressed in the milk. For example, the inclusion of human alpha-lactalbumin gene into a transgenic cow's genome can change the protein profile of the milk, which may result in improved nutritional properties.

Cholesterol and Dietary Health

Cholesterol is a waxy substance found in animal-derived foods like milk and is important for various bodily functions, though its excess consumption is linked to health concerns. Evaluating the cholesterol levels in modified foods, such as milk from transgenic animals, is essential to ensure that the alterations do not adversely affect its health benefits or contribute to dietary issues.

Transgenic Animals

Transgenic animals are organisms that have been genetically modified to include one or more genes from another species, enabling them to exhibit new traits or produce specific proteins. This concept is important because it underpins the ability to produce modified products like milk with enhanced or altered nutritional properties, making them useful in research and biotechnology.

Genetic Engineering in Livestock

Genetic engineering in livestock involves modifying the animal's genetic material to improve productivity, enhance nutritional quality, or produce pharmaceuticals. In the context of transgenic cows, this technology allows the introduction of human genes, which can alter the composition of the milk to potentially offer benefits over normal milk.
