Though CNG produces various weaknesses, it is still widely used on a national scale. It is still uncertain if there would be any considerable increase in the usage of natural gas to power more vehicles. Many parties involved have generally not been able to prove the efficiency of CNG which often resulted in unintentional consequences. Therefore, more research has to be done in terms to find a better and suitable alternative if CNG was to be replaced. However, considering the ever increasing price of gasoline and its benefits to the environment, compressed natural gas seems to be the alternative fuel for the future and is expected to be around.
The process of genetic engineering involves splicing an area of a chromosome, a gene, that controls a certain characteristic of the body. The enzyme endonuclease is used to split a DNA sequence and split the gene from the rest of the chromosome. For example, this gene may be programmed to produce an antiviral protein. This gene is removed and can be placed into another organism. For example, it can be placed into a bacteria, where it is sealed into the DNA chain using ligase. When the chromosome is once again sealed, the bacteria is now effectively re-programmed to replicate this new antiviral protein. The bacteria can continue to live a healthy life, though genetic engineering and human intervention has actively manipulated what the bacteria actually is. No doubt there are advantages and disadvantages, and this whole subject area will become more prominent over time.
