linker dna造句

例句与造句

1. The linker histone, H1, interacts with linker DNA between nucleosomes and functions in the compaction of chromatin into higher order structures.
2. In chromatin neighboring nucleosomes are separated by the linker DNA and in many cases also by the linker histone H1 as well as non-histone proteins.
3. This involves the wrapping of DNA around nucleosomes with approximately 50 base pairs of DNA separating each pair of nucleosomes ( also referred to as linker DNA ).
4. Despite gaps in our understanding, a general model has emerged wherein H1 s globular domain closes the nucleosome by crosslinking incoming and outgoing DNA, while the tail binds to linker DNA and neutralizes its negative charge.
5. It is uncertain whether H1 promotes a solenoid-like chromatin fiber, in which exposed linker DNA is shortened, or whether it merely promotes a change in the angle of adjacent nucleosomes, without affecting linker length.
6. It's difficult to find linker dna in a sentence. 用linker dna造句挺难的
7. Nucleosomes, with about 20 to 60 base pairs of linker DNA, can form, under non-physiological conditions, an approximately 10 nm " beads-on-a-string " fibre . ( Fig . 1-2 ) ..
8. Once the wave reaches the end of the histone octamer the excess that was once at the edge is extended into the region of linker DNA . In total, one round of this method moves the histone octamer several base pairs in a particular direction away from the direction the  wave propagated.
9. Histone H1 was shown to stabilize the structure by winding two turns of linker DNA around the octamer while HMGB1 destabilized the nucleosome by bending adjacent DNA . NMR spectroscopy was again used to show that H1 binds to the acidic tail of HMGB1 via its basic C-terminus, thus halting the HMGB1-DNA interaction.
