    How Does The Central Dogma Connect Dna, Rna, And Proteins?

    The Central Dogma is a basic concept in biology that describes how information flows from DNA to RNA, and then from RNA to proteins. The central dogma was proposed by Francis Crick in 1958 as one of the fundamental principles of molecular biology.

    The Central Dogma

    The central dogma is the idea that DNA makes RNA, which makes proteins. This is a very simple and straightforward model for how we understand genetic information to flow through our cells.

    • DNA is the blueprint: It’s like having a plan for building something in front of you, like an architectural blueprint or mechanical drawing.
    • RNA is the messenger: The messenger transports the plans from point A to point B so they can be used by builders (proteins) who carry out construction projects (making new proteins).
    • Proteins are builders: Builders use these instructions from your DNA to build whatever it was that needed building in order for your body to function properly (e.g., hair follicles).

    DNA makes RNA

    DNA is a double helix, which means it has two strands that are twisted around each other. RNA is single-stranded, meaning it has only one strand of nucleotides. The two strands of DNA and RNA have different chemical groups attached to them–DNA has deoxyribose sugar and phosphate groups; RNA has ribose sugar and phosphate groups.

    When the genetic code in DNA is copied, some of those chemicals get switched out for new ones through a process called transcription (basically copying). This creates messenger RNA (mRNA), which carries information from your genes to ribosomes so they can make proteins based on what they read in mRNA!

    RNA makes proteins

    RNA is a chemical that carries information from DNA to the ribosome. The ribosome reads the RNA and makes a protein, which is then used in the cell. The RNA can be reused again and again, so this process is very efficient because it doesn’t waste any material when making proteins.

    The Genetic Code

    The genetic code is the language of life. It’s a system that translates information from DNA into proteins, which are the building blocks of your body. Each three-letter sequence of nucleotides in an RNA molecule codes for one amino acid in a protein chain. Nucleotides are made up of three components: a phosphate, a sugar and a base (the “R” stands for “ribose”).


    The central dogma is an important concept in biology and genetics. It describes how DNA, RNA and proteins work together in cells to form living organisms.

    The central dogma states that genetic information cannot be passed from protein back to either DNA or RNA–it can only flow from DNA/RNA to protein. This means that the information contained in your genes must first be transcribed into messenger RNA (mRNA), which then directs the synthesis of a specific protein based on its sequence. The mRNA is then degraded so that it can be used again for future transcription events; this process is called translation

    We hope you enjoyed learning about the Central Dogma and how it connects DNA, RNA, and proteins. The next time someone asks you a question about genes or how we inherit traits from our parents, use this information to answer them!
