Based on resonance theory, what is the expected carbon-oxygen bond length(s) for the carbonate anion? (C—O bond = 1.43 Å, C=O bond = 1.22 Å)

Describe the following lone pairs on the 3 nitrogen atoms as localized or delocalized.

The discovery of the structure of double-stranded DNA led to the 1962 Nobel Prize in Physiology and Medicine for James Watson, Francis Crick, and Maurice Wilkins. However, DNA can also form a quadruplex structure with guanidines, which is believed to assist in regulating gene transcription. In the quaduplex shown below, what interaction stabilizes the quadruplex structure?

The enzyme terminase is responsible for:

Rank from weakest to strongest Brønsted base.

Rank in order of longest to smallest bond distances.

Which of the following two elements would have a primarily ionic bond due to their electronegativity difference?

The structure that attaches a chromosome to a microtubule is called a(n):

Alison is heterozygous for a microsatellite locus with alleles of 128 and 135 repeats. Her daughter Jade has alleles of 116 and 128 repeats. Frank has alleles of 135 and 147 repeats. It is possible that Frank is Jade’s father.
