The National Library of Medicine (NLM), on the campus of the National Institutes of Health in Bethesda, Maryland, is the world's largest medical library. The Library collects materials and provides information and research services in all areas of biomedicine and health care.
1) The transfer of genetic information to a bacterium from a bacteriophage or between bacterial or yeast cells mediated by a phage vector.
2) The action or process of converting something and especially energy or a message into another form.
3) The transfer of genetic material from one organism (as a bacterium) to another by a genetic vector and especially a bacteriophage.

1) The twisted-ladder shape that two linear strands of DNA assume when complementary nucleotides on opposing strands bond together.
2) Double helix is the description of the structure of a DNA molecule. A DNA molecule consists of two strands that wind around each other like a twisted ladder. Each strand has a backbone made of alternating groups of sugar (deoxyribose) and phosphate groups. Attached to each sugar is one of four bases: adenine (A), cytosine (C), guanine (G), or thymine (T). The two strands are held together by bonds between the bases, adenine forming a base pair with thymine, and cytosine forming a base pair with guanine.

1) The two complementary, nitrogen-rich molecules held together by weak chemical bonds. Two strands of DNA are held together in the shape of a double helix by the bonds between their base pairs.
2) (bp) Two nitrogenous bases paired together in double-stranded DNA by weak bonds; specific pairing of these bases (adenine with thymine and guanine with cytosine) facilitates accurate DNA replication; when quantified (e.g., 8 bp), refers to the physical length of a sequence of nucleotides.
3) A base pair is two chemical bases bonded to one another forming a "rung of the DNA ladder." The DNA molecule consists of two strands that wind around each other like a twisted ladder. Each strand has a backbone made of alternating sugar (deoxyribose) and phosphate groups. Attached to each sugar is one of four bases--adenine (A), cytosine (C), guanine (G), or thymine (T). The two strands are held together by hydrogen bonds between the bases, with adenine forming a base pair with thymine, and cytosine forming a base pair with guanine.

1) The unit of linkage that refers to the distance between two gene loci determined by the frequency with which recombination occurs between them. Two loci are said to be one centimorgan apart if recombination is observed between them in 1% of meioses.
2) A centimorgan is a unit used to measure genetic linkage. One centimorgan equals a one percent chance that a marker on a chromosome will become separated from a second marker on the same chromosome due to crossing over in a single generation. It translates to approximately one million base pairs of DNA sequence in the human genome. The centimorgan is named after the American geneticist Thomas Hunt Morgan.

1) The univalent radical OH. Hydroxyl radical is a potent oxidizing agent.
2) OH., a neutral, highly reactive, toxic free radical commonly found in biological systems.
3) The chemical group or ion OH that consists of one atom of hydrogen and one of oxygen and is neutral or positively charged.
3) Hydroxide.

1) The uptake by a cell of material from the environment by invagination of its plasma membrane.
2) The uptake of external materials by cells by the invagination of small region of the plasma membrane to form a new intracellular membrane-limited vesicle.
3) Incorporation of substances into a cell by phagocytosis or pinocytosis.

Industry:Health care
1) The use of several DNA sequence polymorphisms (normal variants) that are near or within a gene of interest to track within a family the inheritance of a disease-causing mutation in that gene.
2) A gene-hunting technique that traces patterns of heredity in large, high-risk families, in an attempt to locate a disease-causing gene mutation by identifying traits that are co-inherited with it.

1) The valve between the left atrium and left ventricle of the heart.
2) A valve in the heart that guards the opening between the left atrium and the left ventricle, prevents the blood in the ventricle from returning to the atrium, and consists of two triangular flaps attached at their bases to the fibrous ring which surrounds the opening and connected at their margins with the ventricular walls by the chordae tendineae and papillary muscles -- called also bicuspid valve, left atrioventricular valve.
