Therefore, the DNA nucleotide (Fig. 2.1 ) is composed of a 5-carbon sugar (called deoxyribose), a phosphate group, and a nitrogenous base (nitrogen-containing structure). Note the 5′-carbon (at the top) and the 3′-carbon (at the bottom) of the sugar. Fig.2.1 ......
The backbone of both chains consists of alternating phosphate and sugars (ribose in RNA and deoxyribose in DNA). Attached to the sugar is the nitrogenous base.Answer and Explanation: The phosphodiester bond is the one that exists between the phosphate group and the 5' sugar on one side and ...
ai:phosphate group pentose sugar(deoxyrbose sugar)+nitrogenous base;ii:four different nitrogenous bases attached to pentose sugar:adenine,guanine,cytosine,thymine;b:two strands of DNA joined by H-bonds between A=T and C=G;[students write in full]at high temperature,molecule has high/increased ...
Nucleotides are formed from: a) 3 fatty acids and a glycerol b) 3 monosaccharides and a glycerol c) a fatty acid, a pentose sugar, and 1 or more phosphate groups d) a nitrogenous base, a pentose sugar, and 1 or more phosphate grou...
- Both RNA (ribonucleic acid) and DNA (deoxyribonucleic acid) are types of nucleic acids. They are composed of three main components: a sugar, a phosphate group, and nitrogenous bases. 2. Identify the Nitrogenous Bases in RNA: - RNA contains four nitrogenous bases: adenine (A), guanine ...

The phosphate of one nucleotide is covalently bound (a bond in which one or more pairs of electrons are shared by two atoms) to the sugar of the next nucleotide. The hydrogen bonds between phosphates cause the DNA strand to twist. The nitrogenous bases point inward on the ladder and form ...

Transmission electron microscopy The upper second leaves of the WT and es5 plants were collected at tillering stage and cut into small pieces. The samples were fixed with 2.5% glutaraldehyde in phosphate buffer (0.1 M, pH 7.0) for more than 4 h at 4 °C. The sam- ples were ...
The second difference is that while one of the four nitrogenous bases found in DNA is thymine, the corresponding base in RNA is uracil. The nitrogenous bases of nucleic acids are what dictate the ultimate characteristics of these molecules, because the phosphate and sugar portions do not vary wi...
