A certain bacterial mRNA is known to represent only one gene and to contain about 800 nucleotides.  If you assume that the average amino acid residue contributes 110 to the peptide molecular weight, the largest polypeptide that this mRNA could code for would have a molecular weight of about:

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.
