Phosphate groups on dna
WebEach nucleotide consists of a phosphate group, a nitrogenous base—adenine (A), thymine (T), cytosine (C), or guanine (G)—and deoxyribose. DNA's sugar, deoxyribose, has five carbon atoms, which are connected to each other to form what looks like a ring. Four carbons plus an oxygen are part of the five-sided ring. WebDNA and RNA are composed of nucleotides that are linked to one another in a chain by chemical bonds, called ester bonds, between the sugar base of one nucleotide and the phosphate group of...

The pairing of the nitrogenous … WebThe phosphate group is attached to the 5' carbon of one nucleotide and the 3' carbon of the next nucleotide. In its natural state, each DNA molecule is actually composed of two single strands held together along their length with hydrogen bonds between the bases.
WebJan 21, 2024 · The small molecules that make up DNA are called nucleotides. Each nucleotide contains a phosphate group, a sugar molecule (called deoxyribose ), and a nitrogenous base. A nucleotide There are four types of nitrogenous bases found in DNA molecules. These are: Adenine Guanine Cytosine Thymine 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 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.
