Summary:DNA at the Core of Life Itself, by Lawrence Lessing talks about the details of the genetic key to life, DNA, and how DNA splicing can be used in the future to destroy diseases, help improve medical complications, and even design and alter your own child’s traits. Through decades of research of the DNA molecule, biologists have deciphered the code that determines the inherited characteristics of all living things. This is the information scientists need to be able to control someones own traits. DNA is a double helix found in the chromosome of every living organism on the planet. This microscopic set of “instructions” directs the development and reproduction of every organism. DNA codes for an endless amount of variations through differentiating organisms of different species, even organisms of the same species can have an undetermined amount of differentiating traits from one another. Lawrence also briefly covers the basic organelles of a cell and how it runs, including describing how a mitochondria can produce enough energy to run an entire animal cell and also how the lysosomes of a cell digest it when it has fulfilled its purpose in the organism. Response:This book talks about technology that even in 2018 isn’t being used on humans yet, just that shows how advanced these concepts are, and also how potentially useful these advances could be in the future. The amount of applications in nuclear biology in relation to genetics are vast. With these new technologies we could potentially become a world were physical abnormalities do not exist, but will we be able to surpass the ethic walls we have created as a society to use this new technology in the most useful way possible? Science has come a long way in fighting back against diseases and lengthening the average lifespan but has had almost no advances in the stopping of brain cell deterioration over time. Unlike the rest of the cells in your body, brain cells don’t divide or replenish themselves, they only grow a small amount through life. But, what if we could take part of the coding from a cell that replenish and divides every day, like a skin cell for example, then possibly we could retain some of those lost brain cells over time. Other mental diseases are being researched including mental retardation, there could be a very successful solution involving the use of “brain stimulating devices”. These are very impressive improvements in the mental medical field but the same technology that could be used to turn off mental aggression, for example, could also be used to turn it on. The same medical tools that could be used to block out shocking experiences could also be used by corrupt police to block important memories. There are three different ways molecular genetics could be used to change human nature. The first approach is genetic alchemy, which is were we go directly to the fertilized egg and alter individual genes by changing their DNA. The second option, euphenics, is more indirect, it would involve modifying the functioning of the genes at the developmental stage or later by administering enzymes, hormones, or other chemical agents to make up deficiencies or to get an entirely different effect. The final option is called body cell genetics. This is where you culture tissue lines in which the desired gene combinations are fixed, reset, or repeated, then from them grow full organs for transplants, or possibly even whole organisms. Since each body cell of an organism contains all the DNA coding for the whole organism, you should be able to grow an exact copy of a man by manipulating his tissue cells in a culture (maintain tissue cells in conditions suitable for growth), then letting a set of chromosomes grow inside an egg cell. With these new ideas becoming more and more like a reality, we will have to start finding ways to get past the ethical, legal, and social issues that have never been so important before. These new issues are just becoming a reality because up until this point, none of these new technologies even seemed like a legitimate possibility. These new technologies would be hard to start using not only because of our moral and ethical values, but also because the current laws on molecular genetics and biology are very vague when it comes to human experimentation. Solutions to these ethical and legal problems will need solved soon because of how close we are to unlocking the secret to human modification.
