âBefore, only Acer device owners could use the apps. But from now on, you donât have to own an Acer device,â said Maverick Shih, president of the companyâs Build Your Own Cloud and tablet business.
Histones are the major proteins involved in this packaging. 1  The binding of the chromosomal DNA to histones is the first level of packaging. 2  The DNA-histone protein complex is called the chromatin. 3  There are 5 types of histones namely, H1, H2A, H2B, H3 and H4. The DNA-histone protein complex is called the chromatin. 2  There are 5 types of histones namely, H1, H2A, H2B, H3 and H4. 3  These are basic proteins (25% of basic amino acids lysine and arginine) and negatively charged DNA (due to the presence of phosphate group) can easily bind to these positively charged proteins.
Proteins of DNA Replication. 1  DNA Helicases-These proteins bind to the double stranded DNA and stimulate the separation of the two strands. 2  DNA single-stranded binding proteins-These proteins bind to the DNA as a tetramer and stabilize the single-stranded structure that is generated by the action of the helicases. The DNA molecule is unwound and prepared for synthesis by the action of DNA gyrase, DNA helicase and the single-stranded DNA binding proteins. 2  A free 3'OH group is required for replication, but when the two chains separate no group of that nature exists.
