Multiple Choice
In the context of organic chemistry reactions, how does shotgun cloning differ from the clone-by-clone method?
A
Shotgun cloning is a faster process because it clones entire genomes at once, unlike clone-by-clone which clones one gene at a time.
B
Shotgun cloning requires the use of viral vectors, while clone-by-clone uses bacterial plasmids.
C
Shotgun cloning uses enzymes to selectively clone only the coding regions of DNA, whereas clone-by-clone clones entire chromosomes.
D
Shotgun cloning involves randomly breaking DNA into small fragments and cloning them, while clone-by-clone involves mapping and cloning specific regions.

Understand the basic concept of cloning in the context of genetic research. Cloning involves creating copies of DNA fragments, cells, or organisms.
Recognize that shotgun cloning and clone-by-clone are two different methods used in genomic sequencing.
Shotgun cloning involves randomly breaking the entire genome into small fragments. These fragments are then cloned and sequenced. The sequences are later assembled using computational methods to reconstruct the original genome.
In contrast, the clone-by-clone method involves mapping the genome first to identify specific regions. These regions are then cloned individually, sequenced, and assembled based on the map.
The key difference lies in the approach: shotgun cloning is faster and less precise, as it does not require prior mapping, while clone-by-clone is more methodical, involving detailed mapping and targeted cloning of specific regions.
