Researchers need to know more about how the cancer cells get in and out of the clams and how the retroelement is involved in the disease, she says.
Miller of UCLA of a family of diversity-generating retroelements (DGR's) that function to vary in a precise manner DNA sequences and the proteins they encode.
is pantropic; it permanently integrates its gene sequences into the host cell genome; it has an extraordinarily high mutation/ recombination rate; multiple subtypes are known (see below) to infect a subject at the same time in a single transmitting event; HIV-1 subtypes not only recombine with each other but may also recombine with human endogenous retroelements (11) or human chromosome segments (3,36); HIV-1 infection may activate human endogenous retroelements with or without recombination; and because of compartmentalization, the population dynamics of HIV-1 subtypes differ in different tissue compartments (see below).
and his colleagues at the University of California, Los Angeles, and AvidBiotics, defines the DNA sequences and structures that allow Diversity Generating Retroelements (DGRs) to mutate DNA sequences to direct changes ("diversification") at specific locations in a protein molecule.
