Key Concepts

Genome Sequencing

Genome sequencing is the process of determining the complete DNA sequence of an organism’s genome. This includes every nucleotide—A, T, C, and G—in the DNA, providing a comprehensive map of an organism’s genetic material that can be used for research, diagnostics, and various biotechnological applications.

Shotgun Sequencing

Shotgun sequencing is a method in which the genome is randomly broken into many small fragments that are sequenced in parallel. The resulting sequences, which overlap with one another, are later assembled using computational tools. This approach is efficient and has been widely used in large-scale genome projects.

Fragment Assembly

Fragment assembly is the process of aligning and merging short DNA sequences, obtained by methods such as shotgun sequencing, to reconstruct the original genome. This technique relies on identifying overlapping regions between the fragments to accurately piece together the full genomic sequence.
