DNADeoxyribonucleic acid and ribonucleic acid are two chemical substances involved in transmitting geneticinformation from parent to offspring. It was known early into the 20th century that chromosomes, the geneticmaterial of cells, contained DNA. In 1944, Oswald T. Avery, Colin M. MacLeod, and Maclyn McCartyconcluded that DNA was the basic genetic component of chromosomes. Later, RNA would be proven toregulate protein synthesis. (Miller, 139)DNA is the genetic material found in most viruses and in all cellular organisms. Some viruses do not haveDNA, but contain RNA instead. Depending on the organism, most DNA is found within a single chromosomelike bacteria, or in several chromosomes like

PAGE PAGE 1 The Structure of DNA
The Structure of DNADNA, or deoxyribonucleic acid, is the hereditary material in humans and almostall other organisms. Nearly every cell in a person's body has the same DNA. Most DNAis located in the cell nucleus (it is called nuclear DNA), but a small amount of DNAcan also be found in the mitochondria (U.S. National Library of Medicine, 2009). ADNA molecule consists of two chains of nucleotides (polymers of nucleic acid eachcomposed of a phosphate, a five carbon sugar, and a nitrogenous base) that spiral to formthe double helix shape. The nucleotides that forms the DNA structure are organized sotheir sugar-phosphate components face the outside and form

DNA is usually a double-helix and has two strands running in opposite directions. Each chain is made of subunits called nucleotides.Each strand has a backbone made up of deoxy-ribose sugar molecules (5 sugars) linked together by phosphate groups.Each sugar molecule is covalently linked to one of four possible bases, Adenine, Guanine, Cytosine and Thymine. A and G are larger molecules (called purines) and C and T are smaller molecules (called pyrimidines). In the DNA, the two strands run in opposite directions and the bases pair up so that A always pairs with T and G always pairs with C. The A-T pair has 2 hydrogen bonds and the G-C pair has 3 hydrogen bonds. The G-C interaction is therefore

They want to make an inhibitor that will be more affective at blocking the viral replication and thus slow the onset and progression of the HIV-1 virus.

Genetic Engineering Genetic engineering involves the alteration of an organism's hereditary material in order to eliminate undesirable characteristics or to produce plants with more desirable characteristics. The splicing of genes takes place in order to combine traits that would be unlikely to occur together under ordinary circumstances. "Practices that go back centuries, such as the use of microbes to make wine, cheese, and the selective breeding of livestock and crops, are examples of biotechnology". (Campbell, 1999) These, and other procedures have relied on mutation and genetic recombination. Biotechnology that is based on manipulation of DNA, is different from earlier practices

A gene is a segment of DNA that codes for a protein or a trait. Genes can
be any length and sometimes involve multiple sections of DNA. The HBB
gene provides instructions for making a protein called Beta-globin which is
part of a large protein called hemoglobin that is found in red blood cells.
Each hemoglobin protein can carry four molecules of oxygen, which is
delivered to the body's organs and tissues. If a person doesn't have enough
red blood cells or the cells don't work properly, organs can become deprived

At that point, in the decades following Miescher's revelation, different researchers - exceedingly, Phoebus Levene and Erwin Chargaff- - completed a progression of research attempts that uncovered extra insights about the DNA molecule, including its essential substance parts and the manners by which they joined with each other (Levene, 1919

The specificity due to the structure ensures that metabolic pathways are maintained. Enzymes control all metabolic reactions in the body such as respiration and photosynthesis where rubisco fixes carbon to RuBP in the light-independent reaction. It is highly important that these structures remain intact because otherwise these reactions cannot occur properly. Denaturation can be caused by changes in pH and temperature.

Transcription factors are protins that bind specific sites or elements in regulatory regoions of DNA, known as promoters or enhancers, where they control the transcription or expression of target genes. They are encoded by a unique calss of genes amounting in the animal genome to only a few percent of the total number of protein- coding genes. The recognition of DNA sequence by TFs occurs by chemical interactions of the amino acid side chains of the TF protein with base pair residues of DNA functioning as regulatory sequence. The TFs thus read the genomic sequence and the most fundamental fact about this mechanism is that it is the sequence recognition function ion which informational

A genetically modified organism is "an organism whose genetic structure has been changed by incorporating a gene that will convey a wanted trait, many times called gene splicing" (1). The transferred gene allocates the organism to express a trait that will usually add to its desirability to the producer. To modify the organism, scientists usually use recombinant DNA technology, which uses DNA molecules from different sources are combined in vitro into one molecule to create a new gene, and then this DNA is transferred into an organism and causes the expression of the trait or traits.

In simple terms, you take the stretch of DNA you want to insert into an organism – say, for example, the DNA that makes a carrot produce vitamin A.

Chromosomes are genetic structures found in the nucleus of the cell. Humans have 46 chromosomes in each cell arranged in 23 pairs. Chromosomes are made up of smaller sections called genes, genes are made of short lengths of DNA (deoxyribose nucleic acid). Genes act like codes to control characteristics such as eye colour and hair colour.

research under way to try to find a cure for CF lung disease through gene therapy. Gene therapy is essentially the removing and replacing of a particular gene or set of genes that are dysfunctional with normal functioning genes in an effort to cure a genetic disorder. Gene therapy is performed by using a vector to insert tiny fragments of replacement DNA into a diseased cell's nucleus. A vector is simply a shuttle that is used to carry DNA into a cell and then leave it there for the cell to use. Generally, the vectors used in gene therapy are viruses because a virus can hold onto the DNA as it enters cells, and then deliver the DNA to the cell. The vector is injected into the defective target

The process of transcription occurs throughout the body, creating a copy of the DNA sequence to form an RNA molecule with the opposite nucleotide bases to form essentially a mirror image. As Adenine and Guanine pair together and Thymine and Cytosine together, if there is an A base on the DNA, a G one will be present on the RNA molecule and this pattern is consistent with the other bases with the exception of RNA containing Uracil bases instead of Thymine.

For example, if you find gun residue then you know that a gun was involved. Or if someone got murdered and their is DNA on their skin or fingernails, you can solve the murder by gathering the DNA from the skin and fingernails.

Her cells informed researchers that only matured cells can possibly be immortal. Normal cells are only able to divide a specific amount of time they start dying. Hella cells, just like any other cell, had telomeres. Telomeres has the power to renew the ends off DNA strings in chromosomes. In regular cells, the telomeres shortens the time the cell divides. Once the cell has no more telomeres, the cell dies. With HeLa cells the
