By that definition, one might want to count how many full-length transcripts are present inThis theme will be repeated universally across biology whether the " operator" term is used or not.

The main concept of this theory is that traits are passed from parents to offspring through gene transmission. Genes are located on chromosomes and consist of DNA.

Recombinant definition biology. a cell or organism whose genetic complement results from recombination.Unlike organisms generated by selective breeding, transgenic organisms (also known as recombinant organisms) by definition contain genes from other species. 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 ribosomal RNA (rRNA) genes or transfer RNA (tRNA) genes, the product is a functional RNA.
