STRUCTURE 2 identical single strand RNA molecules that are enclosed within core of virus particle Core contains genetic material, either DNA or RNA – surrounded by protective coat of protein capsid Antigens, glycoproteins on surface recognise receptors on t- lymphocytes also known as CD4 receptors Has reverse transcriptase, integrase and proteasen in it and no internal cell mechanisms Whole cell is around 200nm diameter ..In thin section EM, ribonucleoproteins show themselves to be a distinguishable feature of the HIV particle. In “immature” cells, the RNP is seen to be 18nm wide, with an electron-dense shell, close to the viral lipid bilayer. The condensed core in “mature” cells, however can appear to be different shapes depending on the angle of which the particle is sectioned. This could be, centrosymmetric, tubular-prismatic or triangular. The RNP is contained in an electron dense nucleoid, which is identifiable separate to the

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
