WebThe Central Dogma. Francis Crick coined the phase “the Central Dogma” to describe the flow of information from nucleic acid to protein. Information encoded in DNA is transcribed to RNA, and RNA is translated to a linear sequence of amino acids in protein. Although information can flow reversibly between DNA and RNA via transcription and ... WebRegulation of gene expression, or gene regulation, includes a wide range of mechanisms that are used by cells to increase or decrease the production of specific gene products (protein or RNA).Sophisticated programs of …

Central dogma (DNA to RNA to protein) Biology library

WebThe flow of genetic information in cells from DNA to mRNA to protein is described by the Central Dogma of molecular biology (Figure 16.2). When a cell needs a particular protein, the gene that codes for that protein is activated and a single-stranded mRNA copy is made of the gene, in a process called tr a nscription . WebRegulation often occurs at the level of transcription from DNA into RNA, specifically at the promoter, where RNA polymerase binds the DNA and begins transcription of the gene.

"WebAfter RNA polymerase binds to the promoter, the DNA strands unwind, and the polymerase initiates RNA synthesis at the start point on the template strand. 2) Elongation. The polymerase moves downstream, unwinding the DNA and elongating the RNA transcripts 5' --> 3'. In the wake of transcription, the DNA strands re-form a double helix.

The … WebExceptions to the Central Dogma Many genes code for RNA molecules that do not function as mRNAs and are therefore not translated into proteins. Some RNAs, called rRNA, form parts of the ribosomes. Others form transfer RNAs, or tRNA, which help with translation. Still others can regulate which genes are expressed.
