Core Idea

Shotgun sequencing is treated here as the recurring genome sequencing identity summarized by this source-grounded definition: In genetics, shotgun sequencing is a method used for sequencing random DNA strands. In genetics, shotgun sequencing is a method used for sequencing random DNA strands. It is named by analogy with the rapidly expanding, quasi-random shot grouping of a shotgun. The chain-termination method of DNA sequencing ("Sanger sequencing") can only be used for short DNA strands of 100 to 1000 base pairs.

Scope of Application

  • Documented setting. In genetics, shotgun sequencing is a method used for sequencing random DNA strands.

  • Documented setting. The chain-termination method of DNA sequencing ("Sanger sequencing") can only be used for short DNA strands of 100 to 1000 base pairs.

  • Example. Even so, current methods have failed to isolate or assemble reliable sequence for approximately 1% of the (euchromatic) human genome, as of 2004.

  • Paired-end sequencing. Broader application benefited from pairwise end sequencing, known colloquially as double-barrel shotgun sequencing.

  • Approach. The clones are then sequenced from both ends using the chain termination method yielding two short sequences.

Clarity

A clear use of Shotgun sequencing names the carrier, the operative relation, and the conditions under which the source treats the identity as present. The minimal definition is In genetics, shotgun sequencing is a method used for sequencing random DNA strands. The strongest recognition evidence in the frozen account is: As sequencing projects began to take on longer and more complicated DNA sequences, multiple groups began to realize that useful.

Manages Complexity

Shotgun sequencing compresses multiple genome sequencing details into a stable diagnostic relation. The source shows both the central mechanism—assembly of complex genomes is additionally complicated by the great abundance of repetitive sequences, meaning similar short reads could come from completely different parts of the sequence.—and the practical consequence—if the gap is small (5-20kb) then the use of polymerase chain reaction (PCR) to amplify the region is required.

Abstract Reasoning

  1. Type the carrier. Identify the genome sequencing entities to which the claim applies.
  2. State the relation. Use the source-grounded identity: In genetics, shotgun sequencing is a method used for sequencing random DNA strands.
  3. Check operation and conditions. The first genome sequenced by shotgun sequencing was that of cauliflower mosaic virus, published in 1981.
  4. Demand recognition evidence.

Knowledge Transfer

Within the home domain. Knowledge about Shotgun sequencing transfers literally when a new case preserves the same carrier type, relation, and recognition test. In genetics, shotgun sequencing is a method used for sequencing random DNA strands. The chain-termination method of DNA sequencing ("Sanger sequencing") can only be used for short DNA strands of 100 to 1000 base pairs. Beyond the home domain. No canonical parent is asserted for Shotgun sequencing. An outside case receives the specialist name only when the same typed roles and rejection conditions can be filled literally; otherwise the comparison remains an analogy pending later graph densification.

Neighborhood in Abstraction Space

Shotgun sequencing sits in a moderately populated region (54th percentile for distinctiveness): it has near-neighbors but no dense thicket of look-alikes.
