Diagram of an HIV virion structure Scanning electron micrograph of HIV-1, colored green, budding from a cultured lymphocyte HIV is the cause of the spectrum of disease known as HIV/AIDS. HIV is a retrovirus that primarily infects components of the human immune system such as CD4 + T cells, macrophages and dendritic cells .
The mitochondrial genome of the genus Sphenodon is approximately 18,000 bp in size and consists of 13 protein-coding genes, 2 ribosomal RNA and 22 transfer RNA genes. [ 62 ] DNA methylation is a very common modification in animals and the distribution of CpG sites within genomes affects this methylation.

Duplications of small parts of chromosomes have been the major source of differences between human and chimpanzee genetic material; about 2.7% of the corresponding modern genomes represent differences, produced by gene duplications or deletions, since humans and chimpanzees diverged from their common evolutionary ancestor.

Endometriosis is a disease in which cells like those in the endometrium, the layer of tissue that normally covers the inside of the uterus, grow outside the uterus. [8] [9] It occurs in humans and a limited number of menstruating mammals.
The close genetic relationship between the Han across the entirety of China has led to their characterization as having a "coherent genetic structure". [226] [228] The two notable exceptions to this structure are Pinghua and Tanka people, [231] who on their patrilines, bear a closer genetic resemblance to aboriginal peoples, but have Han ...
