Phosphate group on dna
WebIn a cell, a nucleotide about to be added to the end of a polynucleotide chain will bear a series of three phosphate groups. When the nucleotide joins the growing DNA or RNA chain, it loses two phosphate groups. So, in a chain of DNA or RNA, each nucleotide has just one …

WebDNA structure DNA is a nucleic acid, one of the four major groups of biological macromolecules. Nucleotides All nucleic acids are made up of nucleotides. In DNA, each nucleotide is made up of three parts: a 5-carbon sugar called deoxyribose, a phosphate group, and a nitrogenous base. WebThe sugar-phosphate backbone has a negative charge that allows DNA to easily dissolve in water and is also used by proteins that bind the DNA. These proteins often have positive areas that bind strongly to the negative charge of the phosphate groups. The DNA binding proteins perform important functions like copying the DNA (replication ...
WebApr 8, 2024 · The nitrogenous bases in DNA are of four types – adenine, guanine, thymine and cytosine. The phosphate and the deoxyribose sugars form a backbone-like structure, with the nitrogenous bases extending out … WebDec 24, 2024 · a phosphate group Each nitrogenous base in a nucleotide is attached to a sugar molecule, which is attached to one or more phosphate groups. Figure: DNA and RNA: A nucleotide is made up of three components: a nitrogenous base, a pentose sugar, and one or more phosphate groups.
WebJan 24, 2024 · A free nucleotide may have one, two, or three phosphate groups attached as a chain to the 5-carbon of the sugar. When nucleotides connect to form DNA or RNA, the … WebDeoxyribose sugar +Phosphate + Nitrogen-containing base.

WebThe phosphate group on one nucleotide links to the 3' carbon atom on the sugar of another one. In the process, a molecule of water is lost - another condensation reaction. . . . and you can continue to add more nucleotides in the same way to build up the DNA chain. Now we can simplify all this down to the bare essentials!
WebMar 5, 2024 · DNA contains the pyrimidines cytosine and thymine, and the purines adenine and guanine. Nucleotides are linked together by phosphodiester bonds between the 5ʹ phosphate group of one nucleotide and the 3ʹ hydroxyl group of another.
