The components of the nucleotide used in DNA synthesis are a nitrogenous base, a deoxyribose, and a phosphate group. The nucleotide is named depending on which nitrogenous base is present. The nitrogenous base can be a purine such as adenine (A) and guanine (G), characterized by double-ring structures, or a pyrimidine such as cytosine (C) and ...

The Components & Structure of DNA •Long chain made up of units called nucleotides •Nucleotides are made up of three basic components • 5-carbon sugar = deoxyribose • Phosphate group • Nitrogenous bases • Purines – Adenine and Guanine • Pyrimidines – Thymine and Cytosine The Components & Structure of DNA


The DNA molecule is made up of nucleotides. Each nucleotide contains three different components — a sugar, a phosphate group, and a nitrogen base.


I. DNA has two pyrimidine bases that contain single ring structure. II. In DNA, composition of bases should be G + C A + T = 1. III. Each base pair of DNA is 3. 4 A o apart from other base pairs. IV. The nucleosome model DNA packaging was proposed by Kornberg and Thomas.


Nucleotides and Bases Nucleotides A nucleotide is the basic structural unit and building block for DNA. These building blocks are hooked together to form a chain of DNA. A nucleotide is composed of 3 parts: * five-sided sugar * phosphate group * nitrogenous base (nitrogen containing) The sugar and phosphate group make […]


Nucleotides are chemical compounds that form the basic structure of nucleic acids like RNA and DNA. The chemical structure of nucleotides is almost the same regardless of whether or not the nucleotide is an RNA or DNA nucleotide. Nucleotides are made out of elements like nitrogen and carbon with a nitrogenous base, a five-carbon sugar component, and a group of phosphates.


A nucleotide has a nitrogen-containing base (either purine or pyrimidine). Purine’s bases have adenine and guanine (found in both DNA and RNA) and also have a double ring structure. The pyrimidine bases thymine (found in only DNA) have a single ring structure, and are uracil (found only in RNA), and cytosine (found in both). 2.

When deoxyribonucleotides polymerize to form DNA, the phosphate group from one nucleotide will bond to the 3' carbon on another nucleotide, forming a phosphodiester bond via dehydration synthesis. New nucleotides are always added to the 3' carbon of the last nucleotide, so synthesis always proceeds from 5' to 3'.
