what are similarities between the nitrogenous bases?

The DNA and RNA Structures Nucleotides simply refer to nitrogenous bases, pentose sugar together with the phosphate backbone. Both DNA and RNA have four nitrogenous bases each—three of which they share (Cytosine, Adenine, and Guanine) and one that differs between the two (RNA has Uracil while DNA has Thymine).

Nitrates and nitrites, such as potassium nitrate and sodium nitrite, are naturally occurring chemical compounds which contain nitrogen and oxygen. In nitrates the nitrogen is bonded with three oxygen atoms, while in nitrites the nitrogen is bonded with two oxygen atoms.

A dipole (two poles, positive and negative) is set up and hence a polar bond is created. ... In N2, the atoms bonded to each other are the same and hence have the same electronegativity. As such, the electrons shared are not preferentially drawn to either. This results in the formation of a non-polar bond in N2.

The four nitrogen bases found in DNA are adenine, cytosine, guanine, and thymine. Each of these bases are often abbreviated a single letter: A (adenine), C (cytosine), G (guanine), T (thymine). The bases come in two categories: thymine and cytosine are pyrimidines, while adenine and guanine are purines ().

So NH3 is more polar. ... Considering electronegativity differences, the bond moments of N-H bonds in ammonia are in the direction of lone pair of nitrogen. On the other hand for NF3, the N-F bond moments oppose to that of lone pair. Hence the former is more polar.

Summary. Acid and base properties of organic compounds are much the same as the properties of inorganic acids and bases. There are both strong and weak inorganic acids and bases, however, while organic acids and bases are universally weak acids and weak bases.

Characteristics: Nitrogen is a colorless, odorless, tasteless, diatomic and generally inert gas at standard temperature and pressure. At atmospheric pressure, nitrogen is liquid between 63 K and 77 K.

Nitrates and nitrites are both forms of nitrogen. The difference is in their chemical structures — nitrates have three oxygen atoms, while nitrites have two oxygen atoms.

Nitrogen family elements display a wide range of physical and chemical properties. Their compounds may be transparent, either diamagnetic or paramagnetic at room temperature, and may conduct electricity when heated. Because the atoms form double or triple bonds, the compounds tend to be stable and potentially toxic.

Nitrogen molecule is a non-polar covalent molecule. It has zero dipole moment. Two N atoms in nitrogen molecule have zero electronegativity difference. The bond pairs of electrons are equally distributed between two N atoms.

Basic structure Each nucleotide consists of a nitrogen-containing aromatic base attached to a pentose (five-carbon) sugar, which is in turn attached to a phosphate group. Each nucleic acid contains four of five possible nitrogen-containing bases: adenine (A), guanine (G), cytosine (C), thymine (T), and uracil (U).
