Answer:(1) TIGHT JUNCTIONS
(2) DESMOSOMES
(3) GAP JUNCTIONS
(4) GAP JUNCTIONS
(5) DESMOSOMES.
Explanation: TIGHT JUNCTIONS also known as OCCLUDING JUNCTIONS are junctions present between adjacent cells,tight junctions prevent the passage of materials between the extracellular space of cells.
DESMOSOMES are adhesive intracellular junction connecting adjacent cells,they are also known as anchoring joints which are known to present in tissues where stress are expected.
GAP JUNCTIONS are junctions between cells which allows the movement of ions and small molecules and present in electrically exciteable tissues.

A gene is the set of specific nucleotide sequences, which is present on a chromosome at certain specific places. A gene is responsible for the determination of the traits of any individual. A gene helps in the expression of these traits by the formation of the polypeptides. A gene controls the synthesis of these polypeptides, which then expresses the concerned traits.
Hence, the answer is 'polypeptides'.
