From DNA to Protein

23.4K
The flow of genetic information in cells from DNA to mRNA to protein is described by the central dogma, which states that genes specify the sequence of mRNAs, which in turn specify the sequence of amino acids making up all proteins. The decoding of one molecule to another is performed by specific proteins and RNAs. Because the information stored in DNA is so central to cellular function, it makes intuitive sense that the cell would make mRNA copies of this information for protein synthesis...

DNA as a Genetic Template

28.3K
Two structural features of the DNA molecule provide a basis for the mechanisms of heredity: the four nucleotide bases and its double-stranded nature. The Watson-Crick model of double-helical DNA structure, proposed in 1952, drew heavily upon the X-ray crystallography work of researchers Rosalind Franklin and Maurice Wilkins. Watson, Crick, and Wilkins jointly received the Nobel Prize in Physiology or Medicine for their work in 1962. Franklin was, controversially, excluded from the prize for...

Genome Size and the Evolution of New Genes

9.3K
While every living organism has a genome of some kind (be it RNA, or DNA), there is considerable variation in the sizes of these blueprints. One major factor that impacts genome size is whether the organism is prokaryotic or eukaryotic. In prokaryotes, the genome contains little to no non-coding sequence, such that genes are tightly clustered in groups or operons sequentially along the chromosome. Conversely, the genes in eukaryotes are punctuated by long stretches of non-coding sequence.

    Area of Science:

    • Synthetic Biology
    • Molecular Biology
    • Genetics

    Background:

    • The natural genetic alphabet uses four DNA bases (adenine, guanine, cytosine, thymine) forming two base pairs.
    • Expanding the genetic alphabet is a key goal in synthetic biology for novel applications.

    Purpose of the Study:

    • To engineer a semisynthetic organism with an expanded genetic alphabet.
    • To demonstrate increased genetic information storage capacity.

    Main Methods:

    • Design and synthesis of novel DNA bases.
    • Incorporation of these bases into a living organism's genome.
    • Verification of stable replication and transcription of the expanded genetic material.

    Main Results:

    • Successfully created a semisynthetic organism with a six-letter genetic alphabet.
    • The new alphabet consists of three base pairs, expanding beyond the natural two.
    • The organism demonstrated stable storage of increased genetic information.

    Conclusions:

    • This work expands the fundamental building blocks of life.
    • The engineered genetic system offers new possibilities for information storage and biotechnology.
