Because DNAs for Sequencing Were Chosen at Random with No

question 33

Multiple Choice

Because DNAs for sequencing were chosen at random with no way of knowing which organism they came from,how could genes be identified?

• A)by searching for ORFs,especially those with translation start and stop sites
• B)by searching for similarity between predicted ORFs and those in existing databases
• C)by searching for exons bounded by consensus donor and acceptor splice sites (those that mark exon/intron boundaries)
• D)A and B only
• E)all of the above
