The Central Dogma

The Central Dogma

The central dogma explains the flow of genetic information from DNA nucleotides to the amino acid sequence of proteins.
RNA is the Missing Link Between DNA and Proteins
In the early 1900s, scientists discovered that DNA stores all the information needed for cellular functions and that proteins perform most of these functions. However, the mechanisms of converting genetic information into functional proteins remained unknown for many years. Initially, it was believed that a single gene is...

Methods of Nuclear Reprogramming

Methods of Nuclear Reprogramming

Nuclear reprogramming is a process of transforming one cell type into an unrelated cell type by epigenetic changes that alter the cell’s original gene expression pattern. Such epigenetic changes force cells to express a different set of genes, which play a significant role in inducing transformation into other cell types. Nuclear reprogramming offers applications in reproductive cloning for livestock propagation and regenerative medicine — developing patient-specific cells for...

Introduction to Nuclear Reprogramming

Introduction to Nuclear Reprogramming

Nuclear reprogramming is the process of switching gene expression of one cell type to that of another cell type, usually from a differentiated cell state to an undifferentiated cell state. Differentiation occurs during processes such as development and morphogenesis, tissue regeneration, and malignancy. Cells can also be artificially induced to reprogram their gene expression by techniques such as nuclear transfer, induced pluripotency, and cell fusion. Such techniques have many applications in...

Reporter Genes

Reporter Genes

Reporter genes are a type of protein-coding gene that are often tagged to a gene of interest. Once inside a target cell, reporter genes usually produce visually identifiable characteristics like fluorescence and luminescence when expressed along with the gene of interest. Thus, reporter genes “report” the presence or absence of genes of interest in an organism, determine the gene expression pattern, or track the physical location of a DNA segment or protein in the cell.

Transformation

Transformation

Microbial communities are dynamic environments where cell lysis releases free DNA into the surroundings. Other cells can take up this extracellular DNA through a process known as transformation.When a cell incorporates this foreign DNA into its genome, resulting in genetic modification, the process is known as transformation. Cells capable of this process are termed competent. Competence can be natural, as observed in certain bacteria and archaea, or artificially induced in the...

Genome Size and the Evolution of New Genes

Genome Size and the Evolution of New Genes

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 Computing
Bioinformatics

Background:

Computer science principles have inspired molecular information processing systems.
DNA data storage can approach theoretical limits, but natural genetic encoding is less dense.
Existing gene circuits often contain redundant DNA sequences.

Purpose of the Study:

To test the hypothesis that genetic program function can be maintained with shorter, more information-dense DNA encoding.
To develop and demonstrate a method for compressing genetic programs for efficient storage and execution in cells.

Main Methods:

Developed an experimental procedure for compressing genetic programs.
Implemented autonomous decompression and execution of compressed programs in human cells.
Utilized an RNAi cell classifier circuit as a test case for compression.

Main Results:

Successfully compressed a ten-gene, four-input AND gate circuit into only four genetic constructs.
Demonstrated that compressed genetic programs retain their biological function.
Showcased the potential for increased information content per nucleotide.

Conclusions:

Compression principles can be applied to gene circuits, enabling complex programs in limited DNA delivery vehicles.
Compressed, biologically inert programs can be stored in vivo for later activation.
This approach advances DNA data storage and synthetic biology applications.
