ART significantly extends the likelihood of surviving for several decades, according to the U.S. Department of Health & Human Services. If untreated, HIV-positive persons typically live in clinical latency for around 10 years. Individuals on ART are not likely to have their HIV infection reach the AIDS stage. If the viral infection progresses to that stage, survival is estimated at around three years.
Key concepts: A hydrogen bond is formed by the interaction of a hydrogen atom that is covalently bonded to an electronegative atom (donor) with another electronegative atom (acceptor). Hydrogen bonding confers rigidity to the protein structure and specificity to intermolecular interactions.
The DNA double helix is held together by two types of bonds, covalent and. hydrogen. Covalent bonds occur within each linear strand and strongly bond the. bases, sugars, and phosphate groups (both within each component and between. components). Hydrogen bonds occur between the two strands and involve a base. from one strand with a base from the second in complementary pairing.
