A generic term referring to the four deoxyribonucleotides: dATP, dCTP, dGTP and dTTP. A B C D E F G H I J K L M N O P Q R S T U V W X Y Z ...

Deoxyribonucleotide See nucleotide. Related Terms: Nucleotide A subunit of DNA or RNA consisting of a nitrogenous base (purine in adenine and guanine, pyrimidine in thymine, or cytosine for DNA and uracil cytosine for RNA), a phosphate molecule, ...

Deoxyribonucleotide: See nucleotide. Diploid: A full set of genetic material, consisting of paired chromosomes one chromosome from each parental set. Most animal cells except the gametes have a diploid set of chromosomes.

Deoxyribonucleotide - nucleotides which are the building blocks of DNA and which lack the 2' hydroxyl moiety present in the ribonucleotides of rna.

[edit] Deoxyribonucleotide synthesis In all known organisms, the deoxyribonucleotides that make up DNA are synthesized by the action of ribonucleotide reductase (RNR) enzymes on their corresponding ribonucleotides.

In the cell, all deoxyribonucleotides are synthesized from ribonucleotide precursors. Many bacteria control the transcription and/or translation of certain genes with RNA molecules (Link to "riboswitches") , not protein molecules.

deoxyribonucleic acid (DNA) A polynucleotide having a defined sequence of deoxyribonucleotide units covalently bonded via 3',5'-phosphodiester bonds. Functions in the transmission of genetic information.

Polymerase, DNA or RNA Enzymes that catalyse the synthesis of nucleic acids on preexisting nucleic acid templates, assembling RNA from ribonucleotides or DNA from deoxyribonucleotides. Polymorphism A Difference in DNA sequence among individuals.

DNA is a macro-molecule composed of a long chain of deoxyribonucleotides joined by phospho-diester linkages. Each deoxyribonucleotide contains a phosphate group, the five-carbon sugar 2-deoxribose, and a nitrogen-containing base.

Short preexisting single-stranded polynucleotide chain to which new deoxyribonucleotides can be added by DNA polymerase. It anneals to a nucleic acid template and promotes copying of the template starting from the primer site. Related Terms: ...

deoxyribonucleic acid A polymer of deoxyribonucleotides that is in the form of a double helix; DNA is the genetic molecule of life in that it codes for the sequence of amino acids in proteins; ...

An enzyme that repairs single-stranded discontinuities in double-stranded DNA molecules in the cell. Ligase joins a 3'-OH residue of a deoxyribonucleotide to the 5'-phosphate residue of an adjacent deoxyribonucleotide.

The assay can measure the incorporation of deoxyribonucleotides into acid or ethanol insoluble forms. Gel filtration chromatography or ion exchange chromatography is used to get all protein fractions and is followed by assay for DNA polymerase.

DNA polymerase - catalyzes the addition, of a deoxyribonucleotide to the 3' end of a DNA chain. DNA transcription - process in which molecules of RNA are synthesized in which a strand of DNA acts as a template.

Short preexisting polynucleotide chain to which new deoxyribonucleotides can be added by DNA polymerase. Privacy In genetics, the right of people to restrict access to their genetic information.

They extend the DNA using deoxyribonucleotide triphosphates (dNTP) as substrates and releasing pyrophosphates. The dNMPs are added to the 3' OH end of the growing strand (thus, DNA replication proceeds from 5' to 3' end).

Polymerase -- any enzyme that catalyzes the formation of DNA or RNA from deoxyribonucleotides or ribonucleotides.
