DNA is created a combination of nucleotides joined in a particular order that creates a chain, which can then be duplicated repeatedly. Replication is a matter of matching old strands to a like and complimentary new base.
Ribosomal RNA sort of acts as the blueprints for how to create DNA. RNA is a messenger, which carries information between the DNA, and the cytoplasms ribosomes, (thus earning it the term “messenger RNA”). Transfer RNA on the other hand is created to transport amino acids to the ribosomes.
Genetic variability is a cells ability to adapt to the environmental changes, which are presented to it. If cells were fragile and unable to adapt as quickly or as concisely then humans as a race would be in grave danger due to the overwhelming complications that would result during reproduction. Some of the processes that occur to help create genetic variability include the multitude of cell, which are able to take over for any cells, which are damaged, and the ease with which DNA can be multiplied by the body or through research and development. It is this very genetic variability, which makes projects such as the human genome possible.
The Human Genome Project (HGP) is an international research program has been developed in order to create a documentation of the base pairs along chromosomes as well as to show the sequence of the genes along that chromosome. HGP hopes to decode the entire DNA genome (inheritance) of human beings. Benefits of this type of advance include the overwhelming time saving factor this documented work saves when researchers struggle to define alternate human chromosomes.
This work will help researchers understand the fundamentals of the human body on a molecular level. With understanding of these genomes, researchers will be able to pinpoint specific locations, which may need to be fixed or repaired along the chromosomal band and may even be able to project an individuals susceptibility to specific diseases all based upon their gene make-up.
The Human Genome is a very controversial issue in the way that it will most likely lead to an increase of medications that will be able to help treat a large variety of different diseases, medications will be safer because genome scans will ensure that side effects are better tested on a specific population before it is introduced into the major public, people may have opportunities to live longer through these added safety and health benefits, and finally, yet finally a large moral issue comes into play.
Some people feel that the human genome issue will lead to a choice in the creation of children. Ultimately, people may be able to choose the sex, height, intelligence or major characteristics of their child before he or she is born. Any aspect of religion, race, ethnicity and values comes into play when looking at this possibility. It is because of this controversy that while scientists continue to work to analyze these genomes, they must also spend a great deal of time examining the ethical, social, and legal affects and implications that can result when dealing with the fundamentals of human “blueprints”.
Do you feel that this type of research is ethically controversial? If so, do the possible benefits outweigh possible negatives?
