The blueprint for what every one of us will be like appears at the instant in which the gametes of our father and mother merge to form a single whole, called the zygote or the fertilized egg. The entire message is encapsulated in the nucleus of this single cell -- more precisely, in its DNA molecule. This molecule carries information about the color of our eyes and hair, about our stature, the form of our nose, whether or not we will be a virtuoso musician, and many other things. Of course, our future depends not only on DNA but also on the unpredictable vicissitudes of life. However, many, many thing in our individual destiny will be determined by the qualities built into us at birth by our genes -- that is, by the sequence of nucleotides in our DNA molecules. (Frank-Kamenetskii, 1997, p. 27)
This pairing, will determine the nature of the final being, which will then be affected by its environment to some degree with the inclusion of predisposition of the genetic forms. Gametes, or reproductive cells contain the given and donated DNA. Once the DNA structure creates a reproductive event the gametes then translate this information into a complete being with characteristics of both donors.
There are two categories of cells in multicellular organisms based on their chromosomes: Somatic (another word for "body" cells) and Gametes (reproductive cells). In human gametes, each sperm cell has 23 chromosomes, and each egg cell has 23 chromosomes through the process of Meiosis. This is called the haploid number and is represented by the letter n. When these two gametes get together, they form...
DNA is the abbreviation for deoxyribonucleic acid, which is a complex giant molecule that contains, in chemically coded form, the information needed for a cell to make proteins (DNA Pp). DNA is a "ladderlike double-stranded nucleic acid that forms the basis of genetic inheritance in all organisms, except for a few viruses that have only RNA" (DNA Pp). DNA is organized into chromosomes, and, in organisms other than bacteria, is
Capital Punishment & DNA DNA Evidence, Capital Punishment, & the Criminal Justice System Capital Punishment is an issue of great contention. There are many people who strongly favor the use of capital punishment; there are also a great number of people that are adamantly against the use of capital punishment. DNA (deoxyribonucleic acid) evidence has become a crucial factor in the criminal justice system and the issue of capital punishment. Since the
DNA The Structure and Nature of DNA DNA, or deoxyribonucleic acid, is the basic system upon which life on Earth is constructed. In a very real sense, DNA is a kind of program for life that cells use to replicate themselves and transmit information from generation to generation. Over eons, as life changes and adapts to new environmental conditions, that information is stored in the genetic code of all life on the
DNA in Criminal Justice System DNA in the Criminal Justice System -- DNA as Evidence Justice and Science Sources of DNA at Crime Scene Evidence Collection DNA Evidence on Trial DNA Matching This paper addresses the use of DNA in criminal justice system. The research paper will cover the usage of DNA as evidence. The importance of DNA in any criminal case as forensic evidence will be discussed through case studies. The role of DNA in court
This in turn results in faster convictions and increases the probably of apprehending the culprit in a crime. It can also"... provide compelling evidence to support a conviction and, most importantly, reduce the chances of a wrongful conviction." (Can DNA Demand a Verdict?) The above reasons are indicative of the usefulness and importance of compiling a DNA database from various profiles. Proof of the effectiveness of DNA databases can be
Much of the credit for these exonerations goes to teams of reporters, professors, students, and pro bono attorneys who were willing to listen to the claims of innocence from imprisoned defendants and who dedicated hundreds of hours of uncompensated time to proving these men innocent (Gould, 2008)." In fact, in June of 2009 the Supreme Court of the United States ruled that prisoners do not have the right to DNA
