What is the name of the linkage in nucleotides?
DNA 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 adjacent nucleotide. The sugar is the 3′ end, and the phosphate is the 5′ end of each nucleiotide.
What reaction joins nucleotides together?
condensation reaction
Polymerization of Nucleotides (Phosphodiester Bonds) Nucleotides are joined together similarly to other biological molecules, by a condensation reaction that releases a small, stable molecule.
What is the linkage in nucleic acid?
Thus, the linkage present in nucleic acids is the phosphodiester linkage.
What type of bond holds nucleotides together?
The nucleotides in a base pair are complementary which means their shape allows them to bond together with hydrogen bonds. The A-T pair forms two hydrogen bonds. The C-G pair forms three. The hydrogen bonding between complementary bases holds the two strands of DNA together.
What part of the nucleotides are connected to form a strand?
The nucleotides forming each DNA strand are connected by noncovalent bonds, called hydrogen bonds. Considered individually, hydrogen bonds are much weaker than a single covalent bond, such as a phosphodiester bond.
Where are nucleotides linked together?
phosphate group
Nucleotides are joined together by covalent bonds between the phosphate group of one nucleotide and the third carbon atom of the pentose sugar in the next nucleotide. This produces an alternating backbone of sugar – phosphate – sugar – phosphate all along the polynucleotide chain.
What type of linkage is present in DNA?
Ester bond In DNA, refers to the oxygen-carbon linkage between the triphosphate group and the 5′ carbon of the ribose sugar group in a single DNA or RNA nucleotide.
What type of linkage is present in carbohydrates?
glycosidic linkage
A glycosidic bond or glycosidic linkage is a type of covalent bond that joins a carbohydrate (sugar) molecule to another group, which may or may not be another carbohydrate.
How are nucleotides held together?
The nucleotides are covalently linked together in a chain through the sugars and phosphates, which thus form a “backbone” of alternating sugar-phosphate-sugar-phosphate (see Figure 4-3).
What type of bond is a phosphodiester linkage?
covalent bond
What is a Phosphodiester bond? A phospodiester bond is a covalent bond in which a phosphate group joins adjacent carbons through ester linkages. The bond is the result of a condensation reaction between a hydroxyl group of two sugar groups and a phosphate group.
