Gene synthesis has revolutionized genetic research over the past twenty years by allowing the convenience of DNA storage for a wide range of genome sizes. These libraries have allowed researchers to archive the genes of interested and be able to obtain each gene with relative ease at his or her leisure. Another great advantage ofgene synthetic libraries is the convenient location of the genetic foundation of the organism at your disposal. The genetic foundation can either be stored as the entire genome or more specifically the coding regions of the genome. Gene libraries are mainly broken down into two distinct categories: genomic libraries and cDNA libraries. The two have the same principles and similar output, but are created in different ways and have many different aspects.

First, the genomic libraries is representative of the organism’s entire genome, making the library quite large. The process of creating a genomic library is as follows: first the selected DNA is isolated from the cells by a specific restriction endonuclease. The resulting DNA fragments are then inserted into a selected vector using DNA ligase. Once the DNA is located within the vector, the vector is inserted into a bacteriophage to be amplified. After amplification, the cloned DNA is then isolated again and inserted into a genomic library. This process is then repeated until the entirety of the organism’s genome is isolated, amplified, isolated again, and inserted into the genomic library. Since it is the entire organism’s genome is located in these libraries, including both coding and noncoding regions, these libraries can become quite large. Genomic libraries offer many advantages, such as being able to study gene regulation, or off target effects of a particular mutation. The large amounts of data allow researchers to better understand how mutations, located outside of the coding region of a gene, affect the organism. This extra information is essential to better understand certain mutations, but the large amounts of data can sometimes be problematic. In conclusion, genomic libraries offer more information about the organism, but in turn are more laborious to create and are much larger in size when compared to cDNA libaries.

Second, cDNA library is representative of the organism’s exonic regions, meaning that only the coding regions of the genome are recorded and stored in the library. The process of creating a cDNA library is as follows: mRNA is isolated from a cell of interest and collected. Reverse transcriptase is then used to generate the double stranded cDNA corresponding to the mRNA sequence. Once this is complete, the DNA ends are cleaved to become single stranded and is inserted into a selected vector using DNA ligase. The vector is then inserted into a bacteriophage and amplified. After amplification, the cDNA is isolated and collected in the cDNA library. The cDNA library is much smaller than that of genomic libraries as it only represents the exonic portion of the organism’s genome. This small size is not always problematic, cDNA libraries offer a unique approach to study variant mutations present within coding regions of a gene. In addition to studying variant mutations located within a gene, cDNA libraries also offer a more convenient approach to study protein function, interaction and expression.

Whether you are interested in studying an organism with a very small genome or one as complex and large as a human genome, these two types of libraries are one of the best ways to store data.
