تعريف dna sequence في الإنجليزية الإنجليزية القاموس.
the string of base pairs (adenine, thymine, cytosine, and guanine) which, when arranged in triplets to form codons, create a DNA string which encodes polypeptides
(Biyoloji) In molecular biology and genetics, a transcription factor (sometimes called a sequence-specific DNA-binding factor) is a protein that binds to specific DNA sequences, thereby controlling the flow (or transcription) of genetic information from DNA to mRNA. Transcription factors perform this function alone or with other proteins in a complex, by promoting (as an activator), or blocking (as a repressor) the recruitment of RNA polymerase (the enzyme that performs the transcription of genetic information from DNA to RNA) to specific genes
