The reason segmental duplications pose a logistical challenge in the proper alignment of DNA sequences is that they
A)are inherently repetitive.
B)contain large numbers of LINEs,which interfere with sequence annotation.
C)interfere with BLAST analysis.
D)are often found in areas of constitutive heterochromatin.

Segmental duplications are inherently repetitive, meaning that they occur in multiple copies throughout the genome. This makes it difficult to determine the correct alignment of DNA sequences, as they may match to multiple locations in the genome.
