TNBGGA: The No Bullshit Guide to Genetic Analysis

Promoter: has multiple closely related but subtly different meanings depending on context:

• In bacteriaplugin-autotooltip__default plugin-autotooltip_bigBacteria: Single-celled organisms that also utilize DNA and the standard genetic code as all organisms on earth, but unlike eukaryotes do not have intracellular membranes and membrane-bound organelles. In this book we use bacteria and prokaryote interchangeably., a promoter is a cisplugin-autotooltip__default plugin-autotooltip_bigCis and trans: In genetics, cis and trans are terms used to describe the relative physical locations of genes or genetic elements. If two genes are in cis, this means that they are physically located on the same DNA molecule. If two genes are in trans, this means that they are physically located on two different-acting DNAplugin-autotooltip__default plugin-autotooltip_bigDNA: deoxyribonucleic acid. The genetic material for nearly all life on Earth. sequenceplugin-autotooltip__default plugin-autotooltip_bigSequence: the precise order of monomers in a polymer. In DNA, it refers to the order of G, A, T, and C nucleotides. In RNA, it refers to the order of G, A, U, and C nucleotides. In proteins, it refers to the order of amino acids. near the transcriptionplugin-autotooltip__default plugin-autotooltip_bigRNA transcription: the process of RNA polymerase using the DNA sequence of a gene as a template to form an mRNA (in prokaryotes) or pre-mRNA (in eukaryotes). In most cases, “transcription” implies RNA transcription. start site of a geneplugin-autotooltip__default plugin-autotooltip_bigGene: read Chapters 02, 03, 04, 05, and 06 for a definition of gene :-) or operonplugin-autotooltip__default plugin-autotooltip_bigOperon: two or more genes that are transcribed together on an mRNA from a single promoter.

There are many different types of RNA polymerase, but in this book we collectively refer to them as just “RNA polymerase” for simplicity..

The TATA boxplugin-autotooltip__default plugin-autotooltip_bigTATA box: a short DNA sequence (usually just 6 bp long) that is part of most eukaryotic promoters located around 35-40 bp upstream of the transcription start site.

One reason this is a more inclusive term is because not all enhancers are located upstream of genes; some enhancers are located downstream of a gene, and in some cases can even be located inside a gene. sequencesplugin-autotooltip__default plugin-autotooltip_bigSequence: the precise order of monomers in a polymer.
