In the case of HIV-1, this DNA (now called a DNA provirus) is then integrated into the infected person’s DNA. When the infected person’s DNA is then transcribed, or read by the cell’s molecular machinery, the proviral DNA is also read, leading to the creation of new virus and release from the infected cell. The pathogenesis of HIV-1 infection is complex. HIV-1 binds to cells that have specific types of molecular receptors on their surface, such as CD4 and chemokine receptors. Cells that have these receptors include CD4 lymphocytes, macrophages, and microglial cells in the brain.
Together, the shell and membranes create a safe watery environment in which an embryo can develop from a few cells to an animal with eyes and ears, brain, and heart. Because reptiles, birds, and mammals all have amniotic eggs, they are called amniotes. The duck-billed platypus and some other mammals also lay eggs. But most mammals have evolved amniotic eggs that develop inside the mother’s womb, or uterus, and so lack a shell. In humans and other mammals, the chorion fuses with the lining of the mother’s uterus to form an organ called the placenta.

Amniote Egg The amniotic egg was an evolutionary invention that allowed the first reptiles to colonize dry land more than 300 million years ago. Fishes and amphibians must lay their eggs in water and therefore cannot live far from water. But thanks to the amniotic egg, reptiles can lay their eggs nearly anywhere on dry land. The amniotic egg of reptiles and birds is surrounded by a tough outer shell that protects the egg from predators, pathogens, damage, and drying.
