Double stranded dna structure is composed of pentose sugars phosphate groups and nitrogenous bases

Double stranded dna structure is composed of pentose sugars phosphate groups and nitrogenous bases- · The structure of DNA DNA is a double helix structure because it looks like a twisted ladder The sides of the ladder are made of alternating sugar (deoxyribose) and phosphate molecules while the steps of the ladder are made up of a pair of nitrogen bases As a result of the double helical nature of DNA, the molecule has two asymmetric groovesEach of the sugar groups in this sugarphosphate backbone is linked to one of the four nitrogenous bases Strand of polynucleotides DNA's ability to store and transmit information lies in the fact that it consists of two polynucleotide strands that twist around each other to form a doublestranded helix The bases link across the two strands in a specific manner using

Nucleotide Structure Nucleic acids are long chains (polymers) of lots of nucleotide monomers joined together by phosphodiester bondsEach nucleotide is made up of three components a pentose sugar (either deoxyribose or ribose), a nitrogenous base (guanine, cytosine, adenine, thymine or uracil) and a phosphate groupDNA consists of two nucleic acid strands bondedIt was isolated from pus (leukocytes) from bandages; · One, two or three phosphate groups can be attached to the pentose sugar, producing mono, di and triphosphates respectively Pentose sugar used by DNA is deoxyribose and the pentose sugar used by RNA is ribose Nitrogenous bases found in DNA are adenine, guanine, cytosine and thymine In RNA, thymine is replaced by uracil

Doublestranded DNA molecule (Questions 116) 11_____ Which structural feature is found in the singlestranded DNA molecule?A) It can have a negativelycharged backbone composed of nitrogenous bases b) Each 3',5'phosphodiester bond will contain one phosphate group linking two deoxyribose sugars c) It can have one end with a 5'phosphate group while the other endAn interesting notable fact is that ten (10) base pairs are present in one helix or turn, of the doublestranded DNA A pentose sugar molecule to which the nitrogenous bases are attached at the first carbon (1') and the phosphate molecule, the third main component of

The structure of DNA was first identified as having a 'doublehelix' structure by Watson and Crick in 1953 DNA is composed of 4 bases the purines, adenine (A) and guanine (G) and pyrimidines, thymine (T) and cytosine These form complementary base pairs of AT and GC DNA also contains a phosphate group connected to a deoxyribose sugarDNA double helix has Phosphatesugar backbone The backbone of DNA double helix is made by the sugar and phosphate molecules The polynucleotide chains in DNA are arranged in such a way that the sugar and phosphate molecules are arranged on the outer side of the double helix with the nitrogenous bases facing inwards 5 The two chains are held together by hydrogen bondsDNA Deoxyribose is the pentose sugar found in this type of polynucleotide, hence its name Deoxyribonucleic Acid, or DNA The nitrogenous bases found in DNA are, adenine, guanine, cytosine and thymine DNA molecules have two polynucleotide chains, held together in a ladderlike structure The sugar phosphate backbones of the two chains run parallel to each other in

Concept of DNA 2 Structure of DNA 3 Unusual Bases 4 Replication Concept of DNA DNA is present in the cells of all plants, animals, prokaryotes and in a number of viruses In eukaryotes (eg, Escherichia coli, a bacterium) the genetic material consists of a single giant molecule of DNA about 1,000 microns in length, without any associated proteins DNA is present mainly in theDNA is a two stranded molecule whose shapes resembles a double helix Nucleotides are the Building Blocks DNA (and RNA) are made up of monomers called nucleotides Each individual nucleotide is made up of three components (i) a nitrogenous base (ii) a pentose (fivecarbon) sugar, and (iii) a phosphate groupLinked nucleotides are the phosphatesugar backbone of nucleic acids, and their nitrogenous bases extend from this phosphatesugar backbone like teeth of a comb The Nucleic Acid "Ladder" In DNA, hydrogen bonds form between specific bases of two nucleic acid chains, forming a twisted, doublestranded DNA molecule that looks like a spiral staircase, with the two sugarphosphate

The nucleotide is the elementary unit of nucleic acids They composed of nucleosides and phosphate group A nucleoside is composed of a nitrogen base and pentose sugar Pentose sugars are ribose and deoxyriboseAs you know that nucleic acid are giant molecules having complex structure and very high molecular weight, it contains two types of nitrogenous bases double ring purines and single ringed pyrimidine and two types of Pentose sugars ribose and deoxyribose, it store and transfer information needed for the synthesis of specific proteins that determine the structure andIn the nucleus, DNA is always found as a doublestranded molecule This means that one DNA molecule consists of two DNA strands Each strand is made up of a DNA backbone (the phosphate groups and the pentose sugars) and the bases

Nucleic acids are composed of nucleotides, each of which contains a pentose sugar, a phosphate group, and a nitrogenous base Deoxyribonucleotides within DNA contain deoxyribose as the pentose sugar DNA contains the pyrimidines cytosineThe backbone of DNA is based on a repeated pattern of a sugar group and a phosphate group The full name of DNA, deoxyribonucleic acid, gives you the name of the sugar present deoxyribose Deoxyribose is a modified form of another sugar called ribose I'm going to give you the structure of that first, because you will need it later anywayHe termed the substance nuclein;
