Unformatted text preview: BYS201 Gene Circuits Flow of information in gene expression from genes in the form of DNA to mRNA by transcription and from mRNA to proteins in the form of translation. Gene not only contains information for protein but also regulatory sequences that control when and where to express the gene and how much. Regulatory sequences are analogous to electrical circuits as they process multiple input signals to process output in a very brief time. Gene to Protein : The rules of DNA base pairing allows for sequence of bases on one strand to determine the sequence of the other strand. Genes are units of genetic information stored in the sequences of DNA. Each gene contains information about either a single polypeptide or RNA (tRNA or rRNA). Thus a gene can be defined as a sum total of base sequences of DNA necessary for the synthesis of a functional polypeptide (or RNA molecule) The regulatory sequences (promoters) of a gene could be quite complex,...
