In molecular biology, two nucleotides on opposite complementary DNA or RNA strands that are connected via hydrogen bonds
(Biyoloji) The pair of nitrogenous bases, consisting of a purine linked by hydrogen bonds to a pyrimidine, that connects the complementary strands of DNA or of hybrid molecules joining DNA and RNA. The base pairs are adenine-thymine and guanine-cytosine in DNA, and adenine-uracil and guanine-cytosine in RNA
= (1962): one of the pairs of chemical bases composed of a purine on one strand of DNA joined by hydrogen bonds to a pyrimidine on the other that hold together the two complementary strands much like the rungs of a ladder and include adenine linked to thymine or sometimes to uracil and guanine linked to cytosine See Base-Pair for more information and pictures
Two nucleotide bases on different strands of the nucleic acid molecule that bond together The bases can pair in only one way: adenine with thymine (DNA) or uracil (RNA), and guanine with cytosine
Two nitrogeneous bases (adenine and thymine) or (guanine and cytosine) held together in DNA by weak bonds forming a double helix
The basic units of DNA and RNA, base pairs are chemical structures made up of the chemicals adenine, thymine, guanine and cytosine, which are designated by the letters A, T, G and C, respectively Adenine always pairs with thymine and guanine always pairs with cytosine, creating the pairs or nucleotides in which genetic information is found
Two complementary nucleotides which form a one rung of the DNA ladder
The basic units of DNA, base pairs are chemical structures made up of the chemicals adenine, thymine, guanine and cytosine, which are designated by the letters A, T, G and C, respectively Adenine always pairs with thymine and guanine always pairs with cytosine, creating the pairs or nucleotides in which genetic information is found In RNA, uracil (U) substitutes for thymine (CNN & BIO)
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 (See chemical base )
One unit of DNA composed of two complementary nucleic acid molecules (nucleotides) on opposing strands of DNA The base adenosine always pairs with thymidine; the base guanidine pairs with cytidine
A unit of nucleic acid length, based on the number of paired bases (adenine and thymine, guanine and cytosine) in a DNA double helix
In double-stranded nucleic acids, a "base pair" is the structure formed between two complementary nucleotides by hydrogen bonding In DNA, adenine (A) pairs with thymine (T) and cytosine (C) pairs with guanine (G) In RNA, adenine (A) pairs with uracil (U) and cytosine (C) pairs with guanine (G) See the Figure at NHGRI
A pair of the complementary bases making up DNA In the spiral ladder (double helix) structure of DNA, adenosine always pairs with thymine and cytosine with guanine The size of genes or genomes is often measured by the number of base pairs they contain
Two bases - one on each strand of a double helix, - which interact via hydrogen bonds to maintain DNA in a double-stranded configuration Normally, cytosine forms base pairs with guanine and adenine forms base pairs with thymine
two complementary nucleotides in a piece of DNA joined together by a chemical link The complementary base pairs are: adenine and thymine; guanine and cytosine
one of the pairs of chemical bases joined by hydrogen bonds that connect the complementary strands of a DNA molecule or of an RNA molecule that has two strands; the base pairs are adenine with thymine and guanine with cytosine in DNA and adenine with uracil and guanine with cytosine in RNA
Two nitrogenous bases (adenine and thymine or guanine and cytosine) held together by weak bonds Two strands of DNA are held together in the shape of a double helix by the bonds between base pairs
A pair of complementary nitrogenous bases in a DNA molecule--adenine-thymine and guanine-cytosine Also, the unit of measurement for DNA sequences
Two bases which form a "rung of the DNA ladder " 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 1
Two bases, linked by noncovalent forces, that pair in double-stranded DNA or RNA molecules
Two nucleotide bases (A: T or G: C) held together by weak hydrogen bonds
two nucleotides held together by a weak bond between complementary bases In DNA molecules, adenine is paired with thymine and guanine is paired with cytosine
In DNA, there are four possible bases: cytosine (C), guanine (G), adenine (A), and thymine (T) Cytosine and thymine are pyrimidine bases; adenine and guanine are purine bases Cytosine is complementary to guanine while adenine is complementary to thymine If one strand of DNA has the sequence ATTGC then the complementary strand will be TAACG Two complementary bases constitute a base pair In RNA, thymine is replaced by uracil
the combination of two nucleotides on opposite strands of a DNA molecule that pair up due to the complimentary nature of their nucleotide sequences
Two nitrogenous bases (adenine and thymine or guanine and cytosine) held together by weak bonds The bonds between base pairs hold two strands of DNA together in the shape of a double helix
