For the first installment: chicken breasts, arguably one of the most difficult of the standard meats to grill. It's all too common of an occurrence to get dry, chewy, cardboardy breasts. This is all correctable though, and chicken breasts can be fantastic on the grill, it just takes a little know-how.
In prokaryotic cells, this involves the induction, repression, or enhancement of enzyme synthesis by regulatory proteins (def) that can bind to DNA and either induce, block, or enhance the function of RNA polymerase (def), the enzyme required for transcription.
Gene expression is the process by which information from a gene is used in the synthesis of a functional gene product. These products are often proteins, but in non-protein coding genes such as transfer RNA (tRNA) or small nuclear RNA (snRNA) genes, the product is a functional RNA.n eukaryotes, transcription is performed by three types of RNA polymerases, each of which needs a special DNA sequence called the promoter and a set of DNA-binding proteins -- transcription factors âto initiate the process. RNA polymerase I is responsible for transcription of ribosomal RNA (rRNA) genes.
