Deoxyribonucleic Acid is the meaning of it. It is a nucleic acid that is the carrier of genetic information. Show Explanation:DNA are the letters of deoxyribonucleic acid. All life on earth uses this nucleic acid as the genetic code. A nucleic acid is a polynucleotide. A polynucleotide consists of three basic units: a phosphate group, a 5 carbon sugar (pentose), and a nitrogenous base. The five carbon sugar is deoxyribose. Since a polynucleotide chain, the phosphate and deoxyribose units are repetitive, the variation is provided by the nitrogenous bases. There are four bases: adenine, guanine, cytosine, and thymine. The DNA molecule is double helix, a spiral shaped ladder. The upright or backbone of the ladder is made of alternating pentose and phosphate groups held together by covalent bonds. The rungs or steps of the ladder consist of the bases. These bases are joined to the pentose sugars with covalent bonds. Adenine pairs with thymine using two hydrogen bonds and cytosine pairs with guanine using three hydrogen. The genetic code is determined by the linear sequence of the bases. For example the sequence of adenine guanine thymine does not carry the same message as guanine thymine adenine. The code is arranged in triplet form which codes for RNA which in turn codes for amino acids which form the basis of proteins. Answer link Callum S. Sep 30, 2014 DNA, or deoxyribo nucleic acid, is the structure that codes for the genetic instructions for the development and functioning of an organism. Every organism's DNA is different, and is made up of two strands woven into a double helix shape. DNA is composed of four nitrogen-containing nucleobases; A, T, G, and C, or Adenosine, Thymine, Guanine, and Cytosine. Each base pairs up with another base to form complimentary base pairs, and it is these pairs that form the basis of DNA, as well as a sugar- deoxyribose- and a phosphate group. Proteins and enzymes are also composed of the four bases, and it is these proteins and enzymes that allow the organs in the body to function. For example, the enzymes in the stomach, which are specially designed to withstand the acidic conditions -about pH 2- so that they can digest the food that passes through the digestive system. Answer link sorocraft May 12, 2016 DNA stands for deoxyribonucleic acid. DNA is considered the blueprints for our cells and our body. It contains all of the genetic information that the body needs to grow. Explanation:DNA stands for deoxyribonucleic acid. DNA is considered the blueprints for our cells and our body because it contains all of the genetic information that the body needs to grow. Activities of DNA There are a few components that make the DNA including nitrogenous bases (Adenine and Thymine, Cytosine and Guanine) and the phosphate backbone. Answer link Suren Abreu Oct 15, 2016 DNA is the self-replicating material in almost every living organism that carries genetic information that codes for every function of the cell and/or body (of a multi-cellular organism). Explanation:DNA or deoxyribonucleic acid is the substance of chromosomes which form the genetic material in almost every living organism. It is a helical (twisted around itself) double-stranded structure made up of nucleotides comprising a phosphate group, a sugar group and a nitrogen base. There are four nitrogen bases which are always in pairs: adenine and thymine, guanine and cytosine. The phosphate and sugar groups form the chain or strands while the nitrogen bases connect the strands. It is the sequences of nitrogen bases that form genes that code for particular traits or characteristics. Answer link Dr Birendra Kumar Mishra Jan 24, 2017 DNA is genetic material. Explanation:
Answer link Pop Quiz Whiz Aug 18, 2017 DNA is a long molecule in cells which codes for the building of different molecules. Explanation:DNA, or DeoxyriboNucleic Acid, is a long molecule in all cells. It stores genetic material. DNA is composed of three parts. There is a sugar (deoxyribose), a phosphate group, and a nitrogen base. There are four nitrogen bases, Adenine, Guanine, Cytosine, and Thymine. They can be arranged in different orders to code for various polypeptides (proteins) and other structures the body needs. DNA is double-helical. It is made of two interlocking spirals. In eukaryotic cells, DNA is wrapped around a centrosome to form a chromosome. The chromosomes are located in the nucleus. In prokaryotic cells, the DNA is not located in the nucleus. Answer link Fty Aug 18, 2017 See below Explanation:Deoxyribonucleic acid or DNA is a molecule that contains the genetic materials of an organism. DNA has bases, these bases are thymine, guanine and cytosine. They bind to each other to form the base of DNA and the shape has to be their complementary shape, otherwise they don't bind. Thymine binds with adenine, cytosine with guanine. Each base is attached to sugar and phosphate group, this is then called nucleotides. The nucleotides are arranged into two long strands to form the DNA/double helix. What are the four types of deoxyribonucleic acid?DNA is made up of four building blocks called nucleotides: adenine (A), thymine (T), guanine (G), and cytosine (C).
What are the three types of deoxyribonucleic acid?There are three different DNA types:. A-DNA: It is a right-handed double helix similar to the B-DNA form. ... . B-DNA: This is the most common DNA conformation and is a right-handed helix. ... . Z-DNA: Z-DNA is a left-handed DNA where the double helix winds to the left in a zig-zag pattern.. What are two DNA examples?There are two types of DNA in the cell – autosomal DNA and mitochondrial DNA. Autosomal DNA (also called nuclear DNA) is packaged into 22 paired chromosomes. In each pair of autosomes, one was inherited from the mother and one was inherited from the father.
What is the deoxyribonucleic acid?(dee-OK-see-RY-boh-noo-KLAY-ik A-sid) The molecule inside cells that contains the genetic information responsible for the development and function of an organism. DNA molecules allow this information to be passed from one generation to the next.
