Deoxyribonucleic acid
DNA is a nucleic acid that is basis of genetic information. It is like a set of instructions for our bodies and genetic codes. DNA has many different components that make it up such as hydrogen, oxygen, nitrogen, and phospurous. The structure has two long polymers of a simple unit called nucleotides. Holding the back of the structure is sugar and phosphate which are attached by ester bonds. Bonded to each sugar is 4 different types of molecules called bases. The backbone of the dna is where the genetic information is stored. The code is read by copying stretches of DNA into the related nucleic acid RNA, in a process called transcription.
Properties in DNA once put together make the structure scientists see under the microscope discovered by James D Watson. The structure is two helical chains coiled around the same axis. It’s two long strands twirl around like vines on each other in the shape of a double helix. The nucleotide repeats which is a base linked to sugar and one or more phosphate. The back bone of most DNA strand is made form is made from phosphate and sugar resides. Phosphate is a inorganic chemical that is a sale of phosphoric acid they are mined to obtain phosphorous that is used in agriculture. The sugar in dna is 2 deoxyribose which is pentose which is a 5 carbon sugar. Many bonds hold the dna together such as hydrogen bonds, and phosphodiester bonds. And the four bases are adenine, cytosine, guanine, and thymine. The bases attach to the sugar/phosphate which when attached make up a nucleotide.
DNA plays a dramatic role in todays society such as paternity tests, criminal investigations, and genetic engineering. A forensic scientist can test blood, semen, skin, saliva, or hair found at any crime scene to solve crimes committed. When used for genetic engineering manipulation of the DNA is used and therefore synthetic genes are made and put into things such as food or animals. Genetically modified food has been on the market since 1994. An insulin producing bacteria produced since 1982. This simple yet complicated acid plays important roles from being copied to cure a disease. From holding genetic information Like a CPU for you body. Or solving a murder case. I can honestly say before doing this report I had no idea really what DNA was.

DNA is the blueprint for life, it is found in the nucleus of cells on the chromosomes. It is found in many cell organelles, such as plasmids in bacteria, chloroplasts in plants, and mitochondria in both plants and animals. DNA helps us to perform many actions in solving crimes, and also helps us to do scientific studies that were not possible until recently. DNA has a double helix structure, its sugar phosphate backbone, made up of deoxyribose and a phosphate group are held together by hydrogen bonds and base pairs. These bases are adenine and guanine, thymine and cytosine. There are coding and non coding parts of DNA, the non coding part is called an intron, this may not seem to have a function but it helps to keep the structure of the helix by coiling, regulates when genes are expressed and is also used in DNA replication. Non-coding regions of DNA between genes are the satellite DNA, this is a simple base sequence repeated many times. It’s not all non-coding DNA though, the coding parts of the DNA are known as exons.…

DNA stands for Deoxyribonucleic acid and looks like a spiral. The spiral is also known as a double helix. The strands are made up of our genetic information, composed of genes and chromosomes. There are four bases divided among purines and pyrimidines. On the purines there are Adenine (A) and Guanine (G). On the pyrimidines there are Cytosine (C) and Thymine (T). The base pairs are Adenine and Thymine (A-T) and Cytosine and Guanine (C-G). DNA is found in the nucleus of every human cell. Humans have 46 chromosomes. When a cell reproduces, the chromosomes get copied and distributed to each offspring.…

DNA is composed of two polynucleotide strands wound together into a structure known as a double helix. Each nucleotide consists of a sugar base .Nucleotides form together creating a sugar phosphate backbone to each strand. There are three forms of DNA that differ significantly. The most common, B form, is the structure most people have heard of. It consists of the right handed double helix, with a large major groove and a smaller but accessible minor groove. These grooves are spaces between the backbones which allow access to the bases for interactions with proteins. A form DNA is also a right handed helix, but as yet has not been found in organisms, and only exists in synthetic environments. It has a wider, flatter structure. Z form DNA is found in living organisms, but is a left handed helix, meaning it twists in the opposite direction.…

A molecule of DNA is made up of long chains of polymers and monomers called nucleotides. Those chains, two in particular that compose a strain of DNA, are formed by the grouping of nucleotides into polynucleotides. A nitrogenous base, a sugar, and a phosphate group make up the composition of a nucleotide. In the case of DNA, the four nucleotides that are found along the chain of DNA are thymine (T), cytosine (C), adenine (A), and guanine (G). Those nucleotides are joined by their covalent bonds, more specifically the sugars and phosphates which compose the sugar-phosphate backbone of the polynucleotide.…

DNA made up of units called nucleotides, nucleotides are made up of three molecules components, a nitrogen base, a sugar, and a phosphate (Simon, Reece, Dickey, 2010). The nucleotides are joined together by bonds between the sugar of one nucleotide and the phosphate of the next producing a long chain of nucleotides resulting in a sugar-phosphate backbone (Simon, Reece, Dickey, 2010) the base containing nitrogen is the only part that is variable represented by, A Adenine, C cytosine, G guanine, and T Thymine. The sugars and phosphates form the backbone of the molecule and are on the outside. The bases point inwards horizontally. The antipoarallel strands run in opposite directions and are held together by hydrogen bonds between the base pairs, these two long strands twisted and wrap around each other to form a double helix. Hydrogen bonds between bases hold the strands together; each base pairs with a complementary partner: A with T, and G with C (Simon, Reece, Dickey, 2010).…

Describe the structure of DNA.DNA is thread formed by two strands, related together to form a double helix. The double helix looks like a twisted ladder. The sides of this ladder are long unites called nucleotides and are made of three parts; a nitrogenous base, a sugar, and a phosphate group. The sides of the ladder or the nucleotides from the two separate strands of the DNA are attached by an appendage made of one of four separate bases. These appendages represent the rungs of the DNA ladder and are attached to the complimentary strand of the DNA. The bases or rungs are made of either Adenine (A) OR Thymine (T) or Cytosine (C) and Guanine (G). The attachment of the strands by the bases is specific Adenine can only join with Thymine, and Cytosine can only join with Guanine. Since this base pairing is specific, if one knows the sequence of bases a long one strand of the DNA one will also know the strand of the DNA one will also know the sequence along the complimentary strand.…

DNA is made up of two strands. At one end of each strand there is a phosphate group attached to the carbon atom number 5 of the deoxyribose (this indicates the 5' terminal) and at the other end of each strand is a hydroxyl group attached to the carbon atom number 3 of the deoxyribose (this indicates the 3' terminal). The strands run in opposite directions and so we say that they are antiparallel. One strand runs in a 5'-3' direction and the other runs in a 3'-5' direction. Adjacent nucleotides are attached together via a bond between the phosphate group of one nucleotide and the carbon atom number 3 of the deoxyribose of the other nucleotide.…

DNA is a structure of specific molecules and a complex mixture of chemicals. DNA is a nucleic acid, which is a group of complex compounds that can be found in all living cells or viruses, and controls cell health and function. Nucleic acids are composed of polymers and monomers, which are referred to as nucleotides. There are four different types of nucleotides that make up the structure of DNA, which are abbreviated A, C, T, and G. Covalent bonds join together nucleotides through sugar and phosphate. Polynucleotides, or a polymer nucleotide, which tends to be longer than a monomer nucleotide, contains many variations of arrangements of A, C, T, and G.…
