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.
1. Different kinds of RNA polymerases, depending on whether the product is protein or RNA 2. RNA polymerase requires a number of helper proteins to bind to DNA and initiate RNA synthesis transcription factors 3. Transcription factor TFIID binds to a specific DNA sequence upstream 25 nucleotides from the region coding for the protein TATA sequence or TATA box 4. Other proteins assemble to form a large transcription complex 5.
