The flow of energy starts in in you arms. You put your hands together, and use your arms to move your hands back and forth, this is kinetic energy. Your hands rubbing together causes the molecules to bump into each other, this is friction. As the molecules bump into each other they begin to move faster, and the fast movements of the molecules is what creates heat.

What are the advantages to using prokaryotic as host systems for genetic engineering? What are the limitations to genetic engine
ahrayia [7]

Answer and Explanation:

The manipulation of the gene is called genetic engineering. In genetic engineering, fragments of genes are cloned by leading the genes into the host cell. The advantage of using a prokaryotic host system in genetic engineering is that bacterial cells are used to produce commercially significant products. For example, human growth hormone helps to treat dwarfism, and human insulin production, which is used to treat diabetes. The bacterium P.putida is created by genetic engineering, which is used to break down petroleum products. Genetic engineering also carries some potential risks, such as transferring the selected gene into another speice, benefit one species can harm another speice. Therefore genetic engineering must be used in limit in prokaryotes. These limitations are also addressable in single-cell eukaryotic systems. Biologics-based therapeutic medicines such as a vaccine, gene therapies, and cell therapies known as bioproduction are produced. Medicines are so complex that they can only be formed in a living system. Biopharmaceuticals, value-added food, fuels, chemicals, antibiotics, and many other products are produced by bioproduction.

Genetically identical armadillos were kept in the same controlled environment from birth and provided the same diet. Even though
Vlada [557]

Phenotypic variations in genetically identical organisms that grow in the same controlled environment may be due to mutation.

<h3>Mutation</h3>

This refers to a sudden change to the DNA sequence of living organisms.

When the DNA base sequence of organisms changes, the effect is shown in the morphology of organisms.

For organisms that are genetically identical but grow in different environments, phenotypic variations might exist as a result of environmentally acquired traits during the struggle to adapt to their environments.

In the same environment, however, genetically identical organisms are not expected to be phenotypically different, unless a mutation to the DNA of one has occurred.
