A nucleotide consists of three molecules — a sugar, a phosphate group, and a molecule called a base . If the double helix is a twisted ladder, the sugar and phosphates form the sides of the ladder and pairs of bases form the rungs. There are four different bases, usually abbreviated A...
This chapter discusses nucleotides and nucleic acids. The nucleotides, which consist of three parts, namely, a nitrogenous base, a pentose sugar, and a phosphate radical, are a very important group of compounds as one or more of them is involved in virtually every biochemical process. The ...
A pentose sugar and a nitrogenous base bind together to form a nucleoside. Nitrogenous bases can be adenine, guanine, thymine, cytosine, or uracil. A phosphate group attached to the nucleoside forms a nu...
A five carbon sugar A phosphate molecule A nitrogen-containing base. The sugar carbon atoms are numbered 1 to 5. The nitrogenous base attaches to base 1, and the phosphate group attaches to base 5. DNA polymers are strings of nucleotides. Cells build them from individual nucleotides by linking...
In a DNA chain, all of the 3' and 5' groups of pentose sugar are involved in phosphodiester bonds except for the first and last nucleotide in the chain. The first nucleotide of the chain has an intact 5' phosphate group i.e. it is not bound to any other nucleotide and the last ...
Nucleic acids are molecules that contain and store genetic information. The building blocks of nucleic acids are called nucleotides, which are composed of a phosphate group, sugar, and nitrogenous base.Answer and Explanation: Become a Study.com member to unlock this answ...
base connects to the first or primary carbon of ribose or deoxyribose. The number 5 carbon of the sugar connects to the oxygen of the phosphate group. In DNA or RNA molecules, a phosphate from one nucleotide forms a phosphodiester bond with the number 3 carbon in the next nucleotide sugar....
Complete answer: Nucleotides consist of the components such as a nitrogenous base, sugar, and a phosphate group while the nucleosides contain only sugar and a base. ... A nucleoside consists of a nitrogenous base attached to a sugar(ribose or deoxyribose) with the help of a covalent bond. ...
Nucleotide is the basic unit of nucleic acids which are made up of a nitrogenous base, a phosphate group, and a pentose sugar. The pentose sugar for DNA and RNA are different. The pentose sugar for DNA is 2'-deoxyribose while the pentose sugar for RNA molecule is ribose. For t...
Adjacent nucleotides are held together by a covalent bond called a ___ bond. Nucleotides: Nucleotides are the components of nucleic acids (DNA, RNA), which contain and transfer genetic information. A nucleotide is formed when a sugar molecule is joined to a phosphate...
