Double-stranded oligonucleotides A,B,C,D,and E are sitting in a hot tub discussing 5'-UUUUUUUUUUUUUUU-3', who isn't there. The thermostat breaks and the water starts heating without control. Who is the last to dissociate?

Which is closest to the diameter of a double-stranded DNA molecule.

Under physiological conditions DNA in a cell is

During mitosis, one copy of each chromosome must move to the daughter cells. But chromosomes are very long and the DNA can easily become tangled. Which of the enzymes listed below can untangle DNA?

In a double-stranded polynucleotide, which of the following can base-pair with U?

Which circled element makes the dinucleotide CC shown acidic?

Guanosine might be ?

Polina and Mahmoud are each holding the DNA ends of a small piece of chromatin (Picture - top) containing four nucleosomes. They gently pull the DNA and release the nucleosomes (Picture - bottom) but do not let the DNA ends rotate. Compared to the original, the released DNA is now

Which of the above is purine?

Which histone is not part of the nucleosome core
