Let us make an in-depth study of the gene therapy strategies designed to interfere with the HIV-1 life-cycle. Basically Inhibition has been Envisaged at Three Major Levels: (i) Blocking HIV-1 infection: HIV-1 normally infects T lymphocytes by binding of the viral gp120 envelope protein to the CD4 receptor on the cell membrane. Transfer of a gene encoding a soluble form [...]
The below mentioned article provides notes on overlapping gene. In 1940s, Beadle and Tatum proposed one-gene-one protein hypothesis which explains that one gene encodes for one protein. However, if one gene consists of 1,500 base pairs, a protein of 500 amino acids in length would be synthesized. In addition, if the same sequence read in two different ways, two different [...]
In this article we will discuss about the discovery and evolution of split genes. Discovery of Split Genes: During 1970, in some mammalian viruses (e.g. adenoviruses) it was found that the DNA sequences coding for a polypeptide were not present continuously but were split into several pieces. Therefore, these genes were variously named as split genes or introns, interrupted genes [...]
