Expressed Sequence Tags (ESTs) refer to:

1. Genes expressed as RNA
2. Polypeptide expression
3. DNA polymorphism
4. Novel DNA sequences

Correct answer: Genes expressed as RNA

Solution

Expressed Sequence Tags are short DNA sequences obtained from expressed mRNA after reverse transcription, so they identify genes that are actively transcribed. That makes them markers of genes expressed as RNA, not polypeptides or DNA polymorphisms.
