Question

A researcher has a cDNA molecule of interest, but only possesses expressed sequence tags (ESTs) for this cDNA. This means that:

he knows the complete sequence of this cDNA

he knows the sequence of a short region in the middle of this cDNA.

he knows the sequences of all of the exons present in his cDNA

he knows the sequences of all of the introns present in his cDNA

he could know the sequences of short regions at the 5' and 3' ends of his cDNA

A)

he knows the complete sequence of this cDNA

B)

he knows the sequence of a short region in the middle of this cDNA.

C)

he knows the sequences of all of the exons present in his cDNA

D)

he knows the sequences of all of the introns present in his cDNA

E)

he could know the sequences of short regions at the 5' and 3' ends of his cDNA

Explanation / Answer

he knows the sequence of a short region in the middle of this cDNA.

B)

he knows the sequence of a short region in the middle of this cDNA.
