Recombinant DNA Recombinant DNA is the general name for a piece of DNA that has been created by the combination of at least two strands. Recombinant DNA molecules are sometimes called chimeric DNA, because they can be made of material from two different species, like the mythical chimera.

Life Deoxyribonucleic acid (/diˌɒksiˌraɪbɵ.njuːˌkleɪ.ɨk ˈaesɪd/ ; ˈæSɪD) dna is a molecule that carries most of the genetic instructions used in the, development functioning and reproduction of all known living organisms and many. viruseshe two DNA strands are known as polynucleotides since they are composed of simpler units called nucleotides. Each nucleotide is composed of a nitrogen-containing nucleobase —either cytosine (C), guanine (G), adenine (A), or thymine (T)—as well as a monosaccharide sugar called deoxyribose and a phosphate group.

Recombinant DNA and genetic techniques Recombinant DNA (or rDNA) is made by combining DNA from two or more sources. In practice, the process often involves combining the DNA of different organisms. The process depends on the ability of cut, and re-join, DNA molecules at points identified by specific sequences of nucleotide bases called restriction sites.NA fragments are cut out of their normal position in the chromosome using restriction enzymes (also called restriction endonucleases) and then inserted into other chromosomes or DNA molecules using enzymes called ligases.

DNA Deoxyribonucleic acid (/diˌɒksiˌraɪbɵ.njuːˌkleɪ.ɨk ˈaesɪd/ ; ˈæSɪD) dna is a molecule that carries most of the genetic instructions used in the, development functioning and reproduction of all known living organisms and many. viruseshe backbone of the DNA strand is made from alternating phosphate and sugar residues. The sugar in DNA is 2-deoxyribose, which is a pentose (five-carbon) sugar. The sugars are joined together by phosphate groups that form phosphodiester bonds between the third and fifth carbon atoms of adjacent sugar rings.

- Making the world better, one answer at a time. DNA reproduces through a set process that begins when it unzips and uncoils. Next, two polynucleotide chains are produced and adenine lines up with thymine.Cytosine lines up with guanine, and then hydrogen bonds form between the pairs. Enzymes join the nucleotides together, and two new DNA molecules are formed.NA makes copies of itself through the process of replication.  Because the nucleotide bases are complementary, they automatically  make the other strand of complementary ba … ses when the division of  the cell occurs.

- DNA is made up of molecules called nucleotides. Each nucleotide contains a phosphate group, a sugar group and a nitrogen base. The four types of nitrogen bases are adenine (A), thymine (T), guanine (G) and cytosine (C). The order of these bases is what determines DNA's instructions, or genetic code.

- DNA is made from four chemicals, called nucleotides: adenine, guanine, thymine, and cytosine. Those four chemicals are equivalent to letters that spell out DNA's genetic instructions, just like 26 letters in the English alphabet spell out written instructions.NA also starts to degrade from the moment of death, as the bonds holding the molecule together break apart under assault from water, oxygen and microbes. Some of the best sources of ancient DNA are samples sealed off from the environment, or in natural deep freezes.

- DNA replication is initiated from specific sequences called origins of replication, and eukaryotic cells have multiple replication origins. To initiate DNA replication, multiple replicative proteins assemble on and dissociate from these replicative origins.

DNA: Definition, Structure & Discovery DNA is made up of molecules called nucleotides. Each nucleotide contains a phosphate group, a sugar group and a nitrogen base.

The order of these bases is what determines DNA's instructions, or genetic code.Similar to the way the order of letters in the alphabet can be used to form a word, the order of nitrogen bases in a DNA sequence forms genes, which in the language of the cell, tells cells how to make proteins.NA is made up of molecules called nucleotides.

What is DNA made of? DNA is a very large molecule, made up of smaller units called nucleotides that are strung together in a row, making a DNA molecule thousands of times longer than it is wid … e. Each nucleotide has three parts: a sugar molecule, a phosphate molecule, and a structure called a nitrogenous base. The nitrogenous base is the part of the nucleotide that carries genetic information, so the words nucleotide and base are often used interchangeably.

The DNA molecule has two important properties.

- A DNA molecule is made up of numerous genes and are found on chromosomes. DNA contains monomers called nucleotides, which is made up of a phosphate group, a deoxyribose sugar, … and a nitrogenous base. These nucleotides connect together to form the double-stranded structure, called the double helix.The double helix structure was founded by Watson & Cricke.ucleotides consist of three things: A phosphate groupA deoxyribose sugarAn organic base (A, T, G or C (Adenine, Thymine, Guanine or Cytosine)) … Both the phosphate group and the deoxyribose form the backbone of DNA. This forms the famous helix shape. The organic base is in the middle of the double helix.

What Is a Molecule Produced by Combining DNA From Two Different Sources? To make recombinant DNA, scientists first extract the DNA they want to mix. The DNA can come from completely different organisms, including bacteria, plants, animals, algae or fungi.Using specialized lab techniques, scientists cut the pieces of DNA they want and paste them together to make an entirely new mix of DNA, called recombinant DNA, or rDNA (See References 1).ses for rDNA. DNA from different sources can be mixed to make disease-resistant crops, new vaccines, cures for genetic diseases, and proteins to use in the treatment of conditions such as sickle cell anemia, diabetes, certain cancers and other diseases (See References 2).

Ribosomes, Transcription, and Translation In particular, the two strands of the DNA double helix are made up of combinations of molecules called nucleotides. DNA is constructed from just four different nucleotides — adenine (A), thymine (T), cytosine (C), and guanine (G) — each of which is named for the nitrogenous base it contains.

DNA Nucleic Acids are biopolymers, or large biomolecules, essential for all known forms of life. Nucleic acids, which include DNA (deoxyribonucleic acid) and RNA (ribonucleic acid), are made from monomers known as nucleotides.Each nucleotide has three components: a 5-carbon sugar, a phosphate group, and a nitrogenous base. If the sugar is deoxyribose, the polymer is DNA.If the sugar is ribose, the polymer is RNA.When sugar and a nitrogenous base get combined they form a nucleotide. Nucleotides are also known as phosphate nucleotides. Nucleic acids are among the most important biological macromolecules (others being amino acids/proteins, sugars/carbohydrates, and lipids/fats).f the sugar is ribose, the polymer is RNA. When sugar and a nitrogenous base get combined they form a nucleotide. Nucleotides are also known as phosphate nucleotides. Nucleic acids are among the most important biological macromolecules (others being amino acids/proteins, sugars/carbohydrates, and lipids/fats).
