Your Ad Here	Novacek Michael J. Paleontologist with the American Museum of Natural History. Dr Novacek's research interests include evolution of and relationships among organisms, particularly mammals. Author of Dinosaurs of the Flaming Cliffs, an account of AMNH's Gobi Desert Expeditions. Nuclease Any enzyme that cleaves nucleic acids. Nucleus The cellular organelle in eukaryotes that contains most of the genetic material. 2. The membrane-bound organelle found in eukaryotes that contains the chromosomes and nucleolus. 3. A region of eukaryotic cells, enclosed within a membrane, containing the DNA.
NTD Neural tube defect. A defect occurring in the neural tube that develops into a baby's brain and spine. A defect can occur anywhere along this axis. Nucleolus A nuclear organelle that is involved in ribosome biosynthesis. Nucleoside A purine or pyrimidine base covalently attached to a ribose or deoxyribose sugar molecule. Nurse, Paul A pioneer in genetic and molecular studies who revealed the universal machinery for regulating cell division in all eukaryotic organisms, from yeasts to frogs to human beings.
Nuclear Transfer A laboratory procedure in which a cell's nucleus is removed and placed into an oocyte with its own nucleus removed so the genetic information from the donor nucleus controls the resulting cell. Such cells can be induced to form embryos. This process was used to create the cloned sheep "Dolly". Nucleosome A complex of eight histones, (two each of H2A, H2B, H3, and H4) wrapped by two turns of a DNA molecule. A basic unit of chromatin structure. Nucleolar organizer The chromosomal region around which the nucleolus forms site of tandem repeats of the major ribosomal RNA gene.	Your Ad Here
Nucleic acid A large molecule composed of nucleotide subunits. Nucleolar organizing region A part of the chromosome containing rRNA genes. Null mutation A mutation that makes no gene product at all which in turn can cause a disease state. Numerical taxonomy In general, any method of taxonomy using numerical measurements. In particular, it often refers to phenetic classification using large numbers of quantitatively measured characters.
Your Ad Here	Nucleotide A nucleoside attached covalently to a phosphate group. The basic building block of nucleic acid. Nucleoside A purine or pyrimidine base attached to ribose or deoxy 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). Thousands of nucleotides are linked to form a DNA or RNA molecule.

2. Building blocks of DNA or RNA consisting of a base(adenine, guanine, cytosine and thymine)a molecule of sugar and a phosphate group.

3. A unit :building block of DNA and RNA. A nucleotide consists of a sugar and phosphate backbone with a base attached.

4. One of the monomeric units from which DNA or RNA polymers are constructed, consisting of a purine or pyrimidine base, a pentose, and a phosphoric acid group.

5. A subunit or base of DNA or RNA made up of adenine (A), guanine (G), thymine (T) or cytosine (C) for DNA; A, G, uracil (U) or C for RNA, along with a phosphate molecule and a sugar molecule (deoxyribose in DNA and ribose in RNA). Nucleotides are linked together to form a DNA or RNA molecule.
