Acrylamide does not form, or forms at lower levels, in dairy, meat, and fish products. so the enzymatic degradation of lactose in dairy produts can reduce the acrylamide.

Alpha-lactalbumin is a major milk whey protein. It is involved in the process of lactose synthesis. The first transgenic cow was produced with human alpha-lactalbumin gene introduced into it. The milk of transgenic cow contained about 2.4 grams/lit of human protein.

The replacement principle involves using non-animal alternatives. Improving experimental techniques is part of the 'Refinement' principle, not 'Replacement'.

When the transgenic mice were a few weeks old, they were given drinking water containing zinc. Mice carrying the transgene grew to twice the size of their litter mates because the metallothionein enhancer sequence stimulated by zinc had increased growth hormone production.

Mice are the most frequently used transgenic animals in research, accounting for over 95% of all transgenic animal models due to their biological similarities to humans and ease of genetic manipulation.

Transgenic animals are used for testing chemical safety, testing vaccine safety, and producing pharmaceutical proteins. 'Stimulation of pathogenicity' is not a standard purpose - transgenic animals may model disease but not 'stimulate pathogenicity,' which is poorly phrased and unclear.

Ti plasmid used for tumerogenesis in making transgenic plants belong to Agrobacterium tumificiens.

Agrobacterium tumefaciens is widely used in genetic engineering as a natural vector to transfer foreign DNA into plant cells.

Plasmids are essential in genetic engineering because they possess an origin of replication, allowing them to replicate independently within a host cell.

Agrobacterium is the most common bacterium used in plant genetic engineering due to its natural ability to transfer DNA into plant genomes.
