The histone protein H1 is affixed on top of the nucleosome beaded structure, so as to keep the DNA that has wrapped around the nucleosome in place. It is not found in the core of the nucleosome. H2A, H2B, H3, and H4 are very similar.
There is nothing inherent in the structure of RNA that prevents it forming a double-stranded structure: an RNA strand will pair with (hybridize to) a complementary RNA strand, or with a complementary strand of DNA. Even a single strand of RNA will fold back on itself to form double stranded regions. In particular, transfer RNA (tRNA), and ribosomal RNA (rRNA) both form complex patterns of base.
DNA structure. DNA is the molecule that holds the instructions for growth and development in every living thing. Its structure is described as a double-stranded helix held together by.
