In Eukaryotic chromosomal DNA molecules that have a special nucleotide sequence such as TTAGGG
a structure has two branching "prongs", each one made up of a single strand of DNA. These two strands serve as the template for the leading and lagging strands which will be created as DNA polymerase matches complementary nucleotides to the templates.
segments of repetitive DNA #13, 14, 15, 21 and 22
bead-like structures with 140 base pairs of DNA wrapped around a disc of eight histone proteins.
special proteins that help link mucleosomes together for communication and support
Proteins that bind to the segment of DNA that links neighboring beads.
is acidic, negatively charged and associated with postiviely charged histone proteins.
