A semi-synthetic gene, consisting of the coding sequence from one organism, fused to promoter and other sequences derived from a different gene. Most genes used in transformation are chimeric.
Industry:Biotechnology
A sequence of amino acids linked by peptide bonds; a breakdown or build-up unit in protein metabolism.
Industry:Biotechnology
A sequence of bases that occurs repeatedly in the genome, often end-on-end, i.e., tandemly.
Industry:Biotechnology
A sequence of DNA that is duplicated when a transposable element inserts; usually found at each end the insertion.
Industry:Biotechnology
A sequence of nucleotides at the 5´ end of an mRNA that is not translated into protein.
Industry:Biotechnology
A sequence of nucleotides in a DNA molecule that has the potential to encode a peptide or protein: it starts with a start triplet (ATG), is followed by a string of triplets each of which encodes an amino acid, and ends with a stop triplet (TAA, TAG or TGA). This term is often used when, after the sequence of a DNA fragment has been determined, the function of the encoded protein is not known. The existence of open reading frames is usually inferred from the DNA (rather than the RNA) sequence.
Industry:Biotechnology
A sequence of nucleotides near the 5´ end of a bacterial mRNA molecule that facilitates the binding of the mRNA to the small ribosomal sub-unit. Also called the Shine-Delgarno sequence.
Industry:Biotechnology
A sequence of three nucleotides of DNA which specifies an amino acid. The elucidation of the genetic code involved the binding of charged tRNA species to chemically synthesized ribonucleotide triplets.
Industry:Biotechnology
A series of triplets beginning from a specific nucleotide. Each triplet is represented by a single amino acid in the protein synthesized. The reading frame defines which sets of three nucleotides are read as triplets in the DNA, and hence as codons in the corresponding mRNA; this is determined by the initiation codon, AUG. Thus the sequence
AUGGCAAAAUUUCCC would read as
AUG/GCA/AAA/UUU/CCC/ and not as
A/UGC/CAA/AAU/UUC/CC.
Depending on where one begins, each DNA strand contains three different reading frames.
Industry:Biotechnology
A serum protein, alpha globulin, that interacts with haemoglobin during recycling of the iron molecule of haemoglobin.
