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?

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?

Oligonucleotides A., B., C., and D. are sitting in a test tube at 95°C. The test tube is slowly cooled. Which of the following base-pairing reactions, if any, will happen first?

Shown here is a 5'-UC-3' RNA dinucleotide. Which circled element is responsible for the increased chemical reactivity of RNA compared to DNA?

A piece of double-stranded DNA has 14 base-pairs for each full turn of the helix.

In comparison to euchromatin, the DNA in heterochromatin is:

In a double-stranded polynucleotide, the purine Adenine (A) may base-pair with

The genome of the bacteria E.coli consists of:
