1. A specimen preparation component of a genome extraction device, comprising:
an outer chamber, configured to receive the specimen, partitioned into a plurality of first spaces by an outer chamber partition wall; and
an inner chamber, configured to accommodate a reagent to be used for analysis of the specimen, coupled to the outer chamber through upper openings of the plurality of first spaces and partitioned into a plurality of second spaces by an inner chamber partition wall, the inner chamber having a first position and a second position,
wherein the inner chamber includes
an upper inner chamber in close contact with an inner wall of the plurality of first spaces of the outer chamber,
a lower inner chamber connected to the upper inner chamber and including a curved portion toward a radially inner side from the upper inner chamber so as to be spaced apart from the inner wall of the plurality of first spaces;
lower openings of the plurality of second spaces of the inner chamber are covered by a second sealing member;
a second protrusion member formed on a bottom surface of the plurality of first spaces of the outer chamber, the second position tearing open the second sealing member allowing fluid accommodated in the plurality of second spaces to be introduced into the first spaces of the outer chamber.
