- These nitrogenous bases are adenine (A), uracil (U), guanine (G), thymine (T), and cytosine (C). These nitrogenous bases hydrogen bond between opposing DNA strands to form the rungs of the twisted ladder or double helix of DNA or a biological catalyst that is found in the nucleotides.Adenine is always paired with thymine, and guanine is always paired with cytosine. These are known as base pairs.he main biological function of a nitrogenous base is to bond nucleic acids together. A nitrogenous, or nitrogen-containing, base is an organic molecule with a nitrogen atom that has the chemical properties of a base. A nitrogenous base owes its basic properties to the lone pair of electrons of a nitrogen atom.

Base pair From Wikipedia, the free encyclopedia. Depiction of the adenine-thymine Watson-Crick base pair. Base pairs (unit: bp), which form between specific nucleobases (also termed nitrogenous bases), are the building blocks of the DNA double helix and contribute to the folded structure of both DNA and RNA.

DNA: Adenine, Guanine, Cytosine, Thymine & Complementary Base Pairing The phosphate group and sugar are the same in every nucleotide, but there are four different nitrogenous bases: guanine, adenine, thymine and cytosine. They are often abbreviated by the first letter of each nitrogenous base: G, A, T and C.ou see, cytosine can form three hydrogen bonds with guanine, and adenine can form two hydrogen bonds with thymine. Or, more simply, C bonds with G and A bonds with T. It's called complementary base pairing because each base can only bond with a specific base partner.

Whatâs the difference between discipleship and evangelism? It’s the way disciples are made. So there is not much of a difference between discipleship and evangelism after all. If I’m walking to the rhythm of the gospel in my life and talking about that with other people, I am making disciples.s a result, the discipleship I offered others contained a lot of good information but lacked the transforming power that can only come from the gospel. (I was also, simply, a coward.). I am beginning to see that evangelism and discipleship are not all that different.

- Confidence votes 23. Hydrogen Bonds are the bonds that hold the complimentary bases together. G to C and A to T. However the bonds that hold the nucleotides together on each side of the double helix are called Phosphodiester bonds or linkages. Hydrogen bonding. DNA base pairs are held together by Hydrogen Bonds. Adenine and Thymine have 2 bonds that hold them together while Cysteine and Guanine have 3 bonds that hold them toge … ther. The hydrogen bonds generally occur between a Nitrogen and a carbonyl oxygen.

Nucleic Acid A phosphate group is attached to the 5’ carbon position, the carbon atom that is outside the sugar ring. Each nucleotide includes one nitrogenous base, attached to the 1’ carbon of the sugar. A nitrogenous base is an organic molecule containing both carbon and nitrogen atoms.The name nitrogenous base signifies that several nitrogen atoms act as bases in solution. 5-carbon sugar (ribose or deoxyribose) forms the central molecule in a nucleotide. By convention, the carbon atoms in the sugar are numbered from the original carbonyl position on the chain using a number plus the prime symbol (‘).

How do hydrogen bonds hold DNA together? The hydrogen bonds between the nitrogenous base pairs of DNA are strong dipole-dipole attractions. They hold the two strands of DNA together. > The nitrogenous bases in DNA are A (adenine), C (cytosine), G (guanidine), and T (thymine).

Structural Biochemistry/Nucleic Acid/Nitrogenous Bases Overview [edit]. A DNA nucleotide is composed of 3 main units: a sugar, a phosphate group, and a nitrogenous base. While the sugar and phosphate group alternate in sequence and form the backbone of the DNA double helix, the nitrogenous bases may differ in every adjoining nucleotide.The four nitrogenous bases present in DNA are adenine (A), guanine (G), cytosine (C) and thymine (T).In RNA, the only differing nitrogenous base is uracil (U) (which replaces thymine in DNA and differs thymine only by the missing methyl group at carbon 5 of the pyrimidine ring).hile the sugar and phosphate group alternate in sequence and form the backbone of the DNA double helix, the nitrogenous bases may differ in every adjoining nucleotide.

Structure of Nucleic Acids The nitrogen bases are pyrimidine in structure and form a bond between their 1' nitrogen and the 1' -OH group of the deoxyribose. This type of bond is called a glycosidic bond. The phosphate group forms a bond with the deoxyribose sugar through an ester bond between one of its negatively charged oxygen groups and the 5' -OH of the sugar ().

Structure of Nucleic Acids Base Pairing in DNA. The nitrogen bases form the double-strand of DNA through weak hydrogen bonds. The nitrogen bases, however, have specific shapes and hydrogen bond properties so that guanine and cytosine only bond with each other, while adenine and thymine also bond exclusively.he bases come in two categories: thymine and cytosine are pyrimidines, while adenine and guanine are purines (). The pyrimidine structure is produced by a six-membered, two-nitrogen molecule; purine refers to a nine-membered, four-nitrogen molecule.

DNA: Adenine, Guanine, Cytosine, Thymine & Complementary Base Pairing Professor Pear: Oh, yes. The chemistry of the nitrogenous bases is really the key to the function of DNA. It allows something called complementary base pairing. You see, cytosine can form three hydrogen bonds with guanine, and adenine can form two hydrogen bonds with thymine. Or, more simply, C bonds with G and A bonds with T. It's called complementary base pairing because each base can only bond with a specific base partner.

- A base pair is one of the pairs A-T or C-G. Notice that each base pair consists of a purine and a pyrimidine. The nucleotides in a base pair are complementary which means their shape allows them to bond together with hydrogen bonds. The A-T pair forms two hydrogen bonds. The C-G pair forms three. The hydrogen bonding between complementary bases holds the two strands of DNA together. Hydrogen bonds are not chemical bonds.

- That is, A (adenine) can only form hydrogen bonds with T (thymine) and C (cytosine) can only form bonds with G (guanine). This means, that if you know the sequence of bases of one strand, you know the sequence of bases of the other strand. The strands is such a molecule are said to be complementary.hese strong covalent bonds form the the glue that holds the sugar/phosphate backbone together and thus act to keep each strand together. The two strands of DNA are held together by weak hydrogen bonds (remember, something must hold them together!) between the nitrogenous bases.
