Nucleotides
Nucleic acids are linear, unbranched polymers of nucleotides.
Nucleotides consist of three parts:
1.
A five-carbon sugar (hence a pentose). Two kinds are found: ...

nucleotides The subunits of nucleic acids; composed of a phosphate, a sugar, and a nitrogen-containing base. The fundamental structural unit of the nucleic acid group of organic macromolecules.
nucleotide -- unit from which nucleic acids are constructed by polymerization. It contains a sugar, a phosphate group, and an organic base. ATP is a nucleotide.
Nucleotide: A subunit of DNA or RNA composed of a nitrogenous base, a phosphate molecule, and a pentose sugar molecule.
Pentose sugar: A sugar molecule containing five carbon atoms. E.g.: deoxyribose.
Nucleotide
A nucleoside with a phosphate group attached.
Null
Completely absent. For example, a null mutation completely disrupts a gene.
Nucleotide: A molecular subunit of DNA or RNA consisti ng of a base (adenine, guanine, thymine, or cytosine in DNA; adenine, guanine, uracil, or cytosine in RNA). Thousands of nucleotides are linked to form a DNA or RNA molecule.
Nucleotide: A subunit of DNA or RNA consisting of a nitrogenous base (adenine, guanine, thymine, or cytosine in DNA; adenine, guanine, uracil, or cytosine in RNA), a phosphate molecule, and a sugar molecule (deoxyribose in DNA and ribose in RNA).
nucleotide
(noo-klee-oh-tide) [L. nucleus, a kernel]
The building block of a nucleic acid, consisting of a five-carbon sugar covently bonded to a nitrogenous base and a phosphate group.

Nucleotide. A building block of DNA and RNA, consisting of a nitrogenous base, a five-carbon sugar, and a phosphate group. Together, the nucleotides form codons, which when strung together form genes, which in turn link to form chromosomes.
Nucleotide A building block of a nucleic acid consisting of a base (adenine, thymine, cytosine, guanine, uracil) joined to a sugar (ribose or deoxyribose) and a phosphate.
Null mutation A mutation which leads to the absence of a gene product.
Nucleotide
One of the structural components, or building blocks, of DNA and RNA. A nucleotide consists of a base (one of four chemicals: adenine, thymine, guanine, and cytosine) plus a molecule of sugar and one of phosphoric acid.
Nucleotide kinases Enzymes that transfer the phosphoryl group of one nucleotide to another nucleotide, as in the reaction of ATP with UMP to form UDP and ADP.

Nucleotide
- A compound made up of these three components: a sugar, phosphate and a nitrogen-containing base.
Nucleotides are the building blocks of nucleic acids such as DNA and RNA. They contain a nitrogen-containing base, a 5-carbon sugar, and a phosphate group.
ATP is a nucleotide that contains adenine (base), ribose (sugar), and three phosphate groups.

Nucleotide with opposite orientation of the base sequence and mostly below 50 base pairs. IRs are components of IS elements.
nucleotides - serve as building blocks for the construction of nucleic acids. Nucleoside with one or more phosphate group joined in ester linkages to the sugar moiety. DNA andRNA are polymers of nucleotides. Nucleotide Y nucleoside.
Nucleotide triphosphates (in the forms ATP, GTP, CTP and TTP) are assembled according to the semi-conservative model. Other details of DNA replication are consistent with what we know for prokaryotes.
nucleotide A molecule consisting of phosphate, 5-carbon sugar (ribose or deoxyribose), and a purine or a pyrimidine; the purines are adenine and guanine, and the pyrimidines are cytosine, thymine, and uracil.
Nucleotide = Base + Sugar + Phosphate (1, 2, or 3)
OLIGODEOXYRIBONUCLEOTIDE - A short, single-stranded DNA molecule, generally l5-50 nucleotides in length, which may be used as a primer or a hybridization probe.
Nucleotide positions that can be changed without changing the sequence of a protein are called silent sites. Sites where changes result in an amino acid substitution are called replacement sites.

Codon -- a sequence of three nucleotides in mRNA that specifies an amino acid. Consanguinity -- genetic relationship. Consanguineous individuals have at least one common ancestor in the preceding few generations.
For the human genome, the lowest-resolution physical map is the banding patterns on the 24 different chromosomes; the highest-resolution map would be the complete nucleotide sequence of the chromosomes.
In practice, when synthesising an oligonucleotide primer or probe based on this information a mixture of all the possible sequences is made, and referred to as a degenerate oligonucleotide.
It is proposed that the adenine nucleotide translocase (ANT) is converted into a non-specific pore through a calciummediated conformational change.

The replication process of HIV is associated with a very high mutation rate because reverse transcription does not allow for correction of errors in nucleotide incorporation.
