what is central dogma of life
Answers
Answer
The central dogma of molecular biology describes the two-step process, transcription and translation, by which the information in genes flows into proteins: DNA → RNA → protein. Transcription is the synthesis of an RNA copy of a segment of DNA.

The central dogma of life is the basis of life on earth and required to control the biological processes. Following this hierarchical flow of information from DNA to protein allows nucleus to control all biological activities in a cell. Under normal conditions, the flow of information sequence to sequence requires 3 process. The three process required for flow of information is as follows:
★ Sequence dependent synthesis of DNA from pre-exisitng DNA.
★ Sequence dependent synthesis of RNA from DNA.
★ Sequence dependent synthesis of DNA from pre-exisitng DNA.
