Q. Which of the following is untrue about DNA sequencing?

View solution

Q. In DNA sequencing, the fluorescent traces of the DNA sequences are read by a computer program that assigns bases for each peak in a chromatogram.

View solution

Q. The shotgun approach _______ sequences clones from _____ of cloned DNA.

View solution

Q. The shotgun approach does not require knowledge of physical mapping of the clone fragments, but rather a robust computer assembly program to join the pieces of random fragments into a single, whole-genome sequence.

View solution

Q. Despite the multiple coverage, sometimes certain genomic regions remain unsequenced, mainly owing to cloning difficulties.

View solution

Q. The hierarchical genome sequencing approach is ______

View solution

Q. In hierarchical genome sequencing approach, based on the results of _______ mapping _______of the BAC clones on a chromosome can be determined.

View solution

Q. The hierarchical approach is ____ and _____ than the shotgun approach because it involves an initial clone-based physical mapping step.

View solution

Q. The whole genome shotgun approach can produce a draft sequence very rapidly because it is based on the direct sequencing approach.

View solution

Q. The major challenges in genome assembly are sequence errors, contamination by bacterial vectors, and repetitive sequence regions.

View solution

Q. When a sequence is generated from ____ ends of a single clone, the distance between the two opposing fragments of a clone is fixed to ________ meaning that they are always separated by a distance defined by a _____ length (normally 1,000 to 9,000 bases).
