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.…
Polymers such as DNA and RNA are carry information that is passed from generation to generation. They contain a great amount of linked nucleotides made of sugar, a phosphate and a base. An array of nucleotides in DNA duplicate into a molecule of RNA inside the cell’s nucleus. Before being translated, the RNA navigates its way to the cytoplasm. From the cytoplasm, it is converted in to the specific amino acid sequence of a…
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 is typically has two strands running in opposite direction and is usually referred to as a double helix. Each on the individual strands consists of a backbone that is formed by sugar molecules linked together in groups. Each individual sugar molecule is covalently linked to one of the following possible bases: Adenine, Guanine, Cytosine and Thymine. These bases are typically aligned perpendicular to the axis of the strand. As previously stated the strands run in opposite directions with the bases paired up with Adenine always with Thymine and Guanine always with Cytosine. Theses pairs form hydrogen bonds with the A/T pair having 2 and the G/C pair having 3. The extra hydrogen bond makes the G/C pair stronger.…
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.…

DNA is one of the nucleic acids information-containing molecules in the cell (ribonucleic acid, or RNA, is the other nuclei c acid). DNA if found in the nucleus of every human cell. The information is DNA: guides the cells (along with RNA) in making new proteins that determine all of our biological traits. DNA gets passed (copies) from one generation to the next. DNA in a cell is really just a pattern made up of four different parts called nucleotides. Image a set of blocks that has only four shapes, or an alphabet that has only four letters. DNA is a long string of these blocks or letters.…

Have you ever asked yourself, exactly what is DNA and why is it so important? DNA stands for Deoxyribonucleic Acid and is found in every living thing. We inherit DNA from our parents, half from our mothers and half from our fathers. DNA is made up of sugars, bases, and phosphates and comes in the structure of a double helix which looks like a spiral staircase (Craig Freudenrich, 2007). DNA is found in the genes which are housed in chromosomes. Humans have 46 chromosomes; however, the amount of chromosomes varies from specie to specie. Except in the case of identical twins, DNA is unique…
