Statement: In a modified version of AFLP, the selection of fragments using biotin-streptavidin binding is avoided.
Explanations: I. The fragments are ligated to the appropriate adapters and used for PCR amplification using two AFLP primers, each primer having a single selection nucleotide; this is called preamplification step.
II. The PCR products from this preamplificated step are diluted and used as template for second PCR amplification.

 You are a scientist who is using genomics to currently study a new bacterial species that no one has ever studied before. The following sequence is a piece of DNA within the coding region of a gene that you have recently sequenced.
 
You are using shotgun sequencing to determine the DNA sequence of the genome of this new bacterial species. For one strand of a 30-nucleotide long stretch of DNA, you get the following sequences out of your shotgun sequencing reaction. 
 
Choose correct 30-nt-long DNA sequence with the help of above-mentioned fragments
