问题示例: A metagenomic assembly contains a contig with a high abundance of tetranucleotide patterns characteristic of one organism, but its coverage is twice that of the organism’s other contigs. Which interpretation is most plausible? The contig must be a sequencing contaminant because its coverage is abnormal, The contig may represent a duplicated genomic region or a repeat collapsed during assembly, The organism necessarily has a second, identical chromosome, The contig must originate from a bacteriophage because its coverage is elevated
