Base Pair
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.
Wobble base pair
A wobble base pair is a G-U and I-U / I-A / I-C pair fundamental in RNA secondary structure. It has comparable thermodynamic stability of the Watson-Crick base pair.
Base analog
A purine or pyrimidine base that differs slightly in structure from the normal bases found in DNA or RNA.
Base Pair: Two nitrogenous bases held together by weak bonds. In a DNA molecule adenine always pairs with thymine while cytosine always pairs with guanine. Thus, one DNA strand directs the synthesis of the other strand.
Base
A DNA nucleotide is made of a molecule of sugar, a molecule of phosphoric acid, and a molecule called a base. The bases are the "letters" that spell out the genetic code.
Base (basis oss. sacri)."The base of the sacrum, which is broad and expanded, is directed upward and forward.
base-pair substitution
A point mutation; the replacement of one nucleotide and its partner from the complementary DNA strand by another pair of nucleotides.

Base pair (bp) The fundamental unit of a double stranded DNA molecule, (more strictly - a nucleotide pair). The base Adenine on one strand is paired with Thymine on the other and Guanine with Cytosine.
Base pair (bp). A pair of complementary nitrogenous bases in a DNA molecule--adenine-thymine and guanine-cytosine. Also, the unit of measurement for DNA sequences.
base temperature - The temperature below which an organism does not develop. This parameter is experimentally determined for each organism of interest and used in Degree-Day Models to aid in measuring physiological time.
Base: A compound, usually containing nitrogen, that can accept a H+. It is used to describe the non-sugar components of nucleotides (despite the basic nature of nucleotides, nucleic acids are acidic due to the phosphate atoms they contain).
Base sequence
The order of nucleotide bases in a DNA molecule; determines structure of proteins encoded by that DNA.
Base sequence analysis ...
Base-excision repair A means of repairing DNA in which the damaged base is removed and replaced by a base complementary to the undamaged DNA strand.
BASE COUNT - Base Count gives the total number of adenine (A), cytosine (C), guanine (G), and thymine (T) bases in the sequence.
ORIGIN - Origin contains the sequence data, which begins on the line immediately below the field title.
Base sequence
The order of nucleotide bases in a DNA molecule. Length is usually defined as the number of base pairs. Cf. sequence, DNA sequence.

Base pair
- Two nitrogen bases that pair by hydrogen bonding in the double stranded DNA. The pairing is always a purine with a pyrimidine

base - a molecule that accepts H+ ion (proton)
beta- pleated sheet-A planar secondary structure element of proteins that is created by hydrogen bonding between the backbone atoms in two different polypeptide chains or segment of a single folded chain.
base A substance that ionizes in water to release hydroxyl ions (OH_) or other ions that combine with hydrogen ions.
basic Possessing a large number of hydroxyl (OH_) ions; a pH of more than 7.0.

The DNA base sequence interrupting the protein-coding sequences of a gene; intron sequences are transcribed into RNA but are cut out of the message before it is translated into protein.
Complimentary Base Pairing
Each strand serves as a template for the synthesis of a new strand.
Sequence See base sequence.
Sequence tagged site (STS) Short (200 to 500 base pairs) DNA sequence that has a single occurrence in the human genome and whose location and base sequence are known.
hair bulb The base of a hair; contains cells that divide mitotically to produce columns of hair cells.
hair root The portion of a hair that extends from the skin's surface to the hair bulb.
A nucleotide base triplet in a transfer RNA molecule that pairs with a complementary base triplet, or codon, in a messenger RNA molecule. See Codon, Messenger RNA, RNA. Antigen.
base pair a pair of hydrogen-bonded nitrogenous bases (one purine and one pyrimidine) that join the component strands of the DNA double helix.
Annealing Formation of double-stranded molecules from two single strands of nucleic acid by base pairing of complementary sequence. Usually achieved incubation at a favourable temperature.
These nucleotides are composed of a nitrogenous base (A = adenine, T = thymine, C = cytosine, G = guanine) attached to a sugar called deoxyribose and the sugar is attached to a phosphate group which is negatively charged.
So-called "scientific" creationists do not base their objections on scientific reasoning or data. Their ideas are based on religious dogma, and their approach is simply to attack evolution.
PatMatch The PatMatch program is used to find short nucleotide (less than 30 base pairs) and amino acid motifs in DNA or amino acid sequences.
DNA is a double-stranded molecule held together by weak bonds between base pairs of nucleotides. The four nucleotides in DNA contain the bases adenine (A), guanine (G), cytosine (C), and thymine (T).
The dye stains regions of chromosomes that are rich in the base pairs Adenine (A) and Thymine (T) producing a dark band.
In fact they are held together by hydrogen bonds, a sort of electrical attraction between partially negative atoms on the base of one side with the partially positive atoms on the other. Both sides have positive and negative charges.
