Bases
Base sequence
(Science: molecular biology) The order of nucleotide bases in a dna molecule.
Bases are substances that accept protons from acids.
Let's look at an example.
Acids & Bases Problem Set
Question 6: Relation between H + and OH - concentrations
If the concentration of H + in a solution is 10 - 3 M, what will the concentration of OH - be in the same solution at 25° C?

Bases: The molecular building blocks of DNA and RNA: adenine, cytosine, guanine, thymine, and (in RNA only) uracil. In DNA, A attaches only to T, and C attaches only to G. In RNA, A attaches only to U, and C attaches only to G.
Bases are substances that combine with hydrogen ions, thus lowering the concentration of hydrogen ions.

Notice, for instance, that in the picture below, that the groove on the left side of the picture is much larger than the right side. This is because the paired bases in the center meet each other at an angle.
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.

Sequence
Order of bases in DNA or RNA (base sequence)or of amino acids in a protein.
Peptide
Two or more amino acids joined by a peptide bond.
A pair of complementary nitrogenous bases in a DNA molecule--adenine-thymine and guanine-cytosine. Also, the unit of measurement for DNA sequences. Bioaugmentation.
base pair a pair of hydrogen-bonded nitrogenous bases (one purine and one pyrimidine) that join the component strands of the DNA double helix.
Watson and Crick proposed that the genetic code could be found in the sequence of bases in one of the two strands. (Only one strand carries the genetic message and is "read"...transcribed into mRNA).
The name comes from its structure, which is a sugar and phosphate backbone which have bases sticking out from it--so-called bases. So that "deoxyribo" refers to the sugar and the nucleic acid refers to the phosphate and the bases.
By putting information in a common way into electronic databases available on the web then we make it all, in a very explicit sense, a common venture, so that everybody can contribute to it and draw from it. We need editorial means to do that.
the four nucleotides in dna contain the bases 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).
DNA is a double helix, with bases to the center (like rungs on a ladder) and sugar-phosphate units along the sides of the helix (like the sides of a twisted ladder).

Search for MTHFR in these other databases too
Definition of MTHFR :
MTHFR (methylenetetrahydrofolate reductase) is a metabolic enzyme that is involved in the conversion of homocysteine to methionine.
tRNAs are short (about 74-95 bases), single-stranded RNA molecules that contain a high proportion of modified nucleosides. When drawn in two-dimensions, tRNAs can be folded into a characteristic cloverleaf structure with three stem-loop structures.
The maximum achievable length is around 50 bases, but longer molecules can be constructed using oligonucleotides as building blocks.
Each strand of DNA is composed of a linear array of nucleotides bonded in such a way that the bases extend toward the central axis of the molecule while the two backbones are composed of alternating sugar and phosphate subunits.
