Basic structure of DNA or deoxyribonucleic acid: A nucleotide is the basic of polynucleotide chain of DNA and each nucleotide is composed of three components - i) a nitrogenous base, ii) a pentose sugar and iii) a phosphate group. Nitrogen base is attached to the pentose sugar by an N-gl...
RNA (which is covered in other modules) is composed of ribonucleotides . 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 ...
ICL phosphatescome from a unique integrated phosphate value chain, from phosphate rock mines in the Negev Desert in Israel and in China to value-added downstream production facilities located in Israel, China, Europe, and the USA. As phosphorus is a finite resource, the EU has put phosphorus ...
The molecule that connects the sugars in a strand of DNA is the phosphate group. Each nucleotide has a sugar, a phosphate and a base. The sugar... Learn more about this topic: DNA | Definition, Characteristics & Sequencing from Chapter 4/ Lesson 1 ...
What is DNA made of? DNA is made up of molecules called nucleotides. Each nucleotide contains three components: a phosphate group, which is one phosphorus atom bonded to four oxygen atoms; a sugar molecule; and anitrogenbase. The four types of nitrogen bases are adenine (A), thymine (T)...
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 ...

they connect. This variation in stability can be explained by the 2′-hydroxyl group that is available in RNA, but not in DNA, acting as a neighbor group nucleophile attacking the scissile phosphate. This reaction in nature is supported by enzymes or ribozymes to accelerate the rate of reacti...

· A sugar - In DNA, the sugar group is composed of a 5-carbon sugar deoxyribose· A phosphate - The phosphate is attached to the fifth (5th) carbon of the sugar· The base - The base (nitrogenous base) is attached to the first carbon of the sugar. The bases are divided into two...
