Solution
The sequencing method that would be most problematic to assemble around a 600 bp insertion sequence that was repeated 15 times in a bacterial genome would be Illumina.
Here's why:
Illumina sequencing technology, also known as short-read sequencing, typically generates reads of up to 600 base pairs. This means that if there is a repeated sequence of 600 base pairs in the genome, Illumina sequencing might not be able to distinguish between these repeats. This is because the reads generated by Illumina sequencing might not be long enough to span the entire length of the repeated sequence, making it difficult to accurately assemble the genome around these repeats.
On the other hand, MinIon Nanopore, Sanger, and SMRT sequencing technologies are capable of generating much longer reads. For instance, MinIon Nanopore and SMRT can generate reads of up to tens of thousands of base pairs, while Sanger sequencing can generate reads of up to 1000 base pairs. These longer reads would be able to span the entire length of the repeated sequence, making it easier to accurately assemble the genome around these repeats.
