Why was it necessary to modify the standard sequence assembly algorithms when analyzing DNAs from many different pooled species?
A)Sequencing techniques had improved sufficiently that obtaining accurate repetitive sequences was no longer a technical challenge.
B)Sequence-read lengths of repetitive DNA had increased sufficiently by the time of the Venter et al.work that they were almost as long as the sequences from nonrepetitive DNA.
C)DNAs from abundant organisms would occur frequently in the sample,making them look like repetitive DNAs.
D)DNAs from the largest organisms would occur infrequently in the sample,making them look like repetitive DNA.

When analyzing DNAs from many different pooled species, sequencing a broad range of DNAs tends to produce many reads from the most abundant organisms, making them look like repetitive DNAs. Therefore, it was necessary to modify the standard sequence assembly algorithms to be able to assemble sequences from multiple species and remove redundant sequences from repetitive DNA.
