How do point mutations affect complementary base-pairing and widths of the nucleotide pairs?

Point mutations are divided into two categories: transitions and transversions. Since point mutations only occur during DNA replication (an integral process of both mitosis and meiosis), the mutated ...

Hydrogen bonding in sugar acids

I recently learnt that the reason for low solubility of mucic acid as compared to glucaric acid was more hydrogen bonding in the crystal state of mucic acid as compared to glucaric acid. I would ...

Complementary base pairing

In the molecular structure of a DNA it is seen that purines (adenine and guanine) bind with pyrimidines (cytosine, uracil and thymine) through hydrogen bonds, and this is always between a purine and a ...

Is it possible for Cytosine and Hypoxantine to make three hydrogen bonds?

I think the O from Hypoxanthine can bond with one of the Hs in NH2 from Cytosine and the H that is connected to N in Hypoxanthine with the N in Cytosine but is it possible also for the H connected to ...

Why is the formation of double helix between non complementary sequences disfavoured?

The textbooks starts with the phenomena that double helix is an expression of the rules of chemistry. Hydrogen bonds are important in determining the formation of specific base pairs in the ...

Which atoms in a given amino acid are able to form hydrogen bonds with water?

Can anyone help me with this question I have tried everything. I know hydrogen bonding is with $\ce{F}$, $\ce{O}$, or $\ce{N}$, but every time I select those is says it's wrong.
