The article by the author is an interesting read and contains a whole lot of facts.
The main point the author is driving at is that the ozone hole is getting a kind of healing from its otherwise thought depletion continuation.
What he is trying to say is that, although over the years there has been a rate of decline in the layer, a recent study has shown that the decline rate has in fact slowed down and the hole thought to be on regular depletion is in fact getting healed at a rate in which the depletion has slowed
Ribonucleic acid, the basic unit of RNA, has a hydroxyl (-OH) on the second carbon atom. On the other hand, the deoxyribonucleic acid, the basic unit of DNA, has a single hydrogen in the second carbon. This chemical structure difference makes RNA heavier than DNA due to the extra carbon atom.
The RNA/RNA-DNA hybrids can be separated from double-standard DNA using a high-resolution centrifuge due to this difference in weight. The image belows shows the extra oxygen atom in the 2' carbon
