Answer #1

Nucleic acid hybridization is a technique of visualisation of specific sequence of nucleic acid using a complementary nucleic acid probe. The complementary nucleic acid probe binds to the specific sequence of nucleic acid and give either fluorescence or radioactivity which helps us to determine its location.

So, in this case the DNA will be complementary and antiparallel to the given RNA molecule.

You can design the probe by taking any 15 bases into consideration.

DNA probe : 3' TTAGCTACCAGCTTT 5' (the probe is desgined using the first 15 bases)

Please rate high.
