Both deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) are made up of nucleotides which consist of three parts: Nitrogenous Base. Purines and pyrimidines are the two categories of nitrogenous bases. Pentose Sugar. In DNA, the sugar is 2'-deoxyribose. Phosphate Group. A single phosphate group is PO43-.
3)CTGAGCT. 4) 55. Explanation: 1) A nucleotide (DNA/RNA) comprises of the following. Nitrogenous bases: which are adenine, thymine (only found n DNA), cytosine and uracil (only found in RNA). Pentose sugar: A five carbon sugar called ribose is also one of the components of a nucleotide; Phosphate group: made up of phosphorus and oxygen
For DNA, a lowercase d is often written in front of the sequence to indicate that the monomers are deoxyribonucleotides. The final nucleotide has a free OH group on the 3′ carbon atom and is called the 3′ end. The sequence of nucleotides in the DNA segment shown in Figure 28.1.4 would be written 5′-dG-dT-dA-dC-3′, which is often further ...
What are the three components of a DNA nucleotide? asked Jul 16, 2019 in Biology & Microbiology by kathryncox. A. A phosphate, a base, and a polypeptide B. A sugar, a phosphate, and a peptide C. A sugar, a base, and a polypeptide D. A sugar, a phosphate and a base. general-biology
The diameter of a DNA molecule is 20A °. Space occupied by a turn is 34A °. There are 10 nucleotide pairs in a turn, so space occupied by a nucleotide is 3.4A °. (1nm = 10A °, 1nm =10-9 m). Hydrogen bonds and the plane of one base pair stacks over the other in double helix provides stability to the helical structure.
The three components of a nucleotide ... Sugar - Either ribose or deoxyribose (in RNA or DNA) Nitrogenous base - Adenine, guanine, cytosine, thymine (only in DNA), uracil (only in RNA) Phosphates - One to three, two of which are usually hydrolyzed to provide the energy to attach the nucleotide and form the phosphodiester bond

Surprisingly though there are only a few different nucleotides: only four different nucleotide units comprise DNA, the nucleic acid of interest to the genealogist. This figure is a diagram of a short stretch of a DNA molecule which is unwound and flattened for clarity. The boxed area at the lower left encloses one nucleotide.

1. Draw a simple representation of a nucleotide and name each of the three components. 2. Apply the base pair rule to show how the two strands of a DNA molecule are joined and how a DNA model replicates. 3. [With the Extension Questions] Explain how the Meselson and Stahl experiment supports the semi-conservative model of DNA replication ...
