To describe:
The major types of junctions between the cells.
Introduction:
There are four major types of junctions between the cells. These are gap junctions, desmosomes, tight junctions, and plasmodesmata. While the first three structures are found exclusively in animal cells, plasmodesmata are strictly limited to plant cells. These structures help the cells to interact with their neighboring cells.
To describe:
How the major junctions between the cells function.
Introduction:
The junctions between cells are the specialized structures, which pave way for the cells to interact with their adjacent cells. There are four major types of such junctions, namely Gap junctions, desmosomes, tight junctions, and plasmodesmata. While the first three structures are found exclusively in animal cells, plasmodesmata are strictly limited to plant cells.
To describe:
How gap junctions and plasmodesmata allow direct communication between cells.
Introduction:
Gap junctions allow the passage of small ions and molecules from the cytosol of one animal cell to the other, through the protein channels present in them. On the other hand, plasmodesmata are the junctions present between the cells of plants, throughout the plasma membrane, synonymous to the gap junctions.

- If PCR was performed on the fragment of DNA shown below using "5'-TAGG-3" and "3'-TCTA-5'" as the primers, how many base pairs long would the PCR product be? To help with this, remember the antiparallel structure of DNA and that primers are complementary and antiparallel to the target sequence that they bind to.
