Question

what do you understand by expressed sequence tags?​

Answer 1

Answer:

ESTs are short (200–500 nucleotides) DNA sequences that can be used to identify a gene that is being expressed in a cell at a particular time. This produces complementary DNA (cDNA). Note that cDNA differs from the normal gene in lacking the intron sequences.
