what is the central dogma of life?
Answers
Definition of the Central Dogma of Biology. ... The central dogma of biology describes just that. It provides the basic framework for how genetic information flows from a DNA sequence to a protein product inside cells. This process of genetic information flowing from DNA to RNA to protein is called gene expression.
Hello mate
✨ Central Dogma of life✨
Life of an organism required co-ordinated function of different organs or tissues. Even in the unicellular system, cellular processes are controlled by a series of molecular events, mostly controlled by signal transduction. Signal transduction is a series of phosphorylation events performed by protein kinases. In addition, co-ordination between different organs through messenger molecules, which are also be proteinous in nature. In addition, the phenotypic changes (skin color, feather and pattern) in an organism are required for adaptation and biological demands such as selecting suitable life partner. Most of these examples are associated with the synthesis of suitable protein factor in a time and context dependent manner. The protein is made up of amino acids and every protein has unique amino acid arranged in a specific sequence. The information to synthesize proteins with unique amino acid sequence is provided by the nucleic acid present within the nucleus. In a preset sequence, DNA present in the nucleus give rise to the specific RNA sequence and that in turn guide the cellular machinery to synthesize protein . Scientist considered this as the fundamental event to run the life and considered as “central dogma of life”. In another word Francis in his communication to jounrla Nature states “The central dogma of molecular biology deals with the detailed residue-by-residue transfer of sequential information. It states that such information cannot be transferred back from protein to either protein or nucleic acid”.
