What type of bonds does base-pairing in DNA involve?
The bases are being "paired" with 2 or 3 hydrogen bonds.
In DNA, 4 different base pairs are lined up in two strands to create a certain sequence that, in the end, codes for many different proteins. The 4 different bases are:
- Adenine (A)
- Thymine (T)
- Guanine (G)
- Cytosine (C)
Adenine will normally pair up with thymine, and guanine will pair up with cytosine.
A-T
G-CBetween both pairs, hydrogen bonds play the main role of holding them together. The difference between the two pairs is that between A and T, there are 2 hydrogen bonds, while between C and G, there are 3 hydrogen bonds.
This explains why, for example, C-T pairing is unfavourable.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
