Question

Quizplus · Accepted Answer

Sequence annotation involves identifying genes and other functional elements within a genome. One common approach is to identify open reading frames (ORFs), which are stretches of DNA that are likely to encode proteins. Shotgun cloning involves randomly breaking up DNA into small fragments for sequencing, which is not necessary once the complete genomic sequence has already been determined. The alignment of contigs refers to the process of assembling the genome sequence from smaller overlapping fragments, which has also already been completed in this scenario. The construction of a genetic map involves determining the location and order of genes on a chromosome, which is not relevant for sequence annotation. Therefore, the best option for sequence annotation is the identification of open reading frames.
