We have looked at the cloning experiments involved in producing Snuppy. Describe the specific technique that was used and how th
Sergio039 [100]

Answer:

Cloning may be defined as the process by which the genetically identified individual of the organism can be created artifically or naturally. Aseual reproduction results in the formation of clone.

The microsatellite analysis is used to prove that snuppy is a clone. Microsatellites are the highly variable DNA sequences repeats that has variable loci and considered at population level. The two alleles are possible for the one microsatellite locus. After comparing the alleles it has been found that snuppy has exactly the same genetic material as the surrogate mother, afghan. This completely determines that snuppy is a clone of afgan.

likoan [24]

The salivary glands, stomach, and pancreas secrete<u> lipase enzymes</u> to break down triglycerides into monoglycerides, fatty acids, and glycerol.

Lipases are a set of water-soluble enzymes that hydrolyze substrates such as triglycerides and phospholipids, have a similar structure and are essential in the metabolism of lipoproteins and lipids.

That is, the function of lipase enzymes is to hydrolyze triglycerides to generate diglycerides, monoglycerides, fatty acids and glycerol.

<u>About lipase enzymes</u>:

  • It acts on the neutral fats in the diet, splitting them into triglycerides or diglycerides and these to monoglyceride, which is the most easily absorbed fatty compound.

  • The action of lipase is much more manifest on triglyceride, and it is also much faster the higher the molecular weight of the fatty acid present.

  • It acts on the surface and in an aqueous medium, the emulsifying agent represented by bile salts is essential for optimum effectiveness.

  • They are widely distributed, with a presence in the animal and plant kingdoms and even in the simplest unicellular organisms.

Therefore, we can conclude that the salivary glands, stomach, and pancreas secrete lipase enzymes to break down triglycerides into monoglycerides, fatty acids, and glycerol.
