Nucleotides are joined together by a Condensation Reaction between the Phosphate Group of one and the Sugar Group of another. The bond between the two monomers is called a Phosphodiester Bond.

What reaction binds nucleotides together?
Nucleotides are linked together by the formation of a phosphodiester bond which is formed between the 3' -OH group of one sugar molecule, and the 5' phosphate group on the adjacent sugar molecule. This results in a loss of a molecule of water, making this a condensation reaction, also called a dehydration synthesis.
What is it called when nucleotides combine?
The nucleotides combine with each other to form a polynucleotide: DNA or RNA.
Are nucleotides joined together by peptide bonds?
Peptide bonds are formed between the carboxylic acid group of one amino acid and the amino group of a second amino acid. ... Nucleotides are covalently linked to one another via the formation of phosphodiester bonds between the sugar group of one nucleotide and the phosphate group of a second nucleotide.
What DNA enzyme covalently links nucleotides together?
As the new nucleotides line up opposite each parent strand by hydrogen bonding, enzymes called DNA polymerases join the nucleotides by way of phosphodiester bonds.
How do the nucleotides in DNA pair?
Nucleotides form a pair in a molecule of DNA where two adjacent bases form hydrogen bonds. The nitrogenous bases of the DNA always pair up in specific way, purine with pyrimidine (A with T, G with C), held together by weak hydrogen bonds. ... The molecule appears as a twisted ladder and is called a double helix.
What is the relationship between the nucleotides nucleic acids and DNA?
A nucleotide is the basic building block of nucleic acids. RNA and DNA are polymers made of long chains of nucleotides. A nucleotide consists of a sugar molecule (either ribose in RNA or deoxyribose in DNA) attached to a phosphate group and a nitrogen-containing base.
Is DNA single-stranded?
DNA can exist in different forms – single-stranded (ssDNA) or double-stranded (dsDNA). DsDNA exists in double helixes, where two strands of DNA wind around each other. SsDNA can fold into different shapes but is usually stellate or star-shaped.
How do nucleotides join together to form nucleic acid?
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 reaction joins amino acids together?
Within a protein, multiple amino acids are linked together by peptide bonds, thereby forming a long chain. Peptide bonds are formed by a biochemical reaction that extracts a water molecule as it joins the amino group of one amino acid to the carboxyl group of a neighboring amino acid.
How are nucleic acids joined together?
Alternating sugar molecules and phosphate groups are bonded together to form the backbone of the nucleic acid, and a purine or pyrimidine base is bonded to each of the sugars, as illustrated below. ... DNA consists of two nucleotide chains that are bonded to together by weak hydrogen bonds between complementary base pairs.
Which enzyme covalently links nucleotides together quizlet?
coli polymerases I, II, and III have 3' to 5' activity, which provides them with a proofreading function, i.e. they can remove a mispaired base. Which of these is not one of the three phases of DNA replication? The enzyme DNA covalently links nucleotides to synthesize new DNA strands together during DNA replication.
How do nucleotides enter the cell?
The Nucleotide Transporters. ... Concentrative transporters translocate nucleosides into a cell against a thermodynamic gradient by coupling transport to the electrogenic cotransport of sodium ions into the cell.
How do nucleotide bases form a code?
Genetic code is the term we use for the way that the four bases of DNA--the A, C, G, and Ts--are strung together in a way that the cellular machinery, the ribosome, can read them and turn them into a protein. In the genetic code, each three nucleotides in a row count as a triplet and code for a single amino acid.
Why is the nucleotide sequence of DNA important?
Together, all of the DNA "sentences" within a cell contain the instructions for building the proteins and other molecules that the cell needs to carry out its daily work. ...
Which bases pair up together in DNA?
DNA base pair. Under normal circumstances, the nitrogen-containing bases adenine (A) and thymine (T) pair together, and cytosine (C) and guanine (G) pair together. The binding of these base pairs forms the structure of DNA .
When can a DNA be single stranded?
A DNA molecule consisting of only a single strand contrary to the typical two strands of nucleotides in helical form. In nature, single stranded DNA genome can be found in Parvoviridae (class II viruses). Single stranded DNA can also be produced artificially by rapidly cooling a heat-denatured DNA.
Where does SSB bind DNA?
Single-strand DNA-binding protein (SSB) is a protein found in Escherichia coli (E. coli) bacteria, that binds to single-stranded regions of deoxyribonucleic acid (DNA). Single-stranded DNA is produced during all aspects of DNA metabolism: replication, recombination, and repair.
