What Are Gene Fragments?
Gene fragments are short sequences of DNA that represent a portion of a gene or a collection of genes. These fragments are synthetically constructed to match exact sequences required for various scientific and medical applications. Unlike full genes, gene fragments are smaller and easier to handle, making them ideal for use in research and development processes where specific genetic sequences are needed.
| Term | Description | Uses | What Clients Need to Provide |
|---|---|---|---|
| Gene Fragments | Short sequences of DNA representing part of a gene | Cloning, gene editing, synthetic biology, diagnostics | Desired DNA sequence, length, any specific modifications |
| Full Genes | Entire sequences of DNA coding for a specific protein | Protein expression, genetic studies, functional assays | Full gene sequence, target organism for expression |
| Synthetic Construction | Creation of DNA sequences to match specific requirements | Custom research applications, gene therapy, drug development | Exact nucleotide sequence, codon optimization preferences |
Process of Synthesis
The synthesis of gene fragments involves designing the desired DNA sequence, chemically synthesizing the sequence, assembling the short DNA oligonucleotides into larger fragments, and verifying the accuracy of the synthesized gene fragments. Gene fragments are crucial in cloning and research due to their precision, speed, and the ability to customize sequences for specific experimental needs. The synthesis of gene fragments involves several key steps:
