What does hydrogen bonding have to do with proteins, DNA, RNA proteins and prions?

Question

I know hydrogen bonding is essential for the function and structure of numerous molecules, but how is it specifically necessary for the function of proteins, DNA, RNA, proteins and prions?

Answer 1

Sci219 made a lot of mistakes.

A lot of RNAs have secondary structures. rRNA , tRNA and ribozymes have SS permanently, mRNAs frequently. RNA form structure by the same way as DNA plus complexes containing Mg or Mn.

Sulfhydryl is group (-SH), bond is disulfide (-S-S-).

Prions are proteins.

Answer 2

In these macromolecules, bonding between parts of the same macromolecule cause it to fold into a specific shape, which helps determine the molecule's physiological or biochemical role. The double helical structure of DNA, for example, is due largely to hydrogen bonding between the base pairs, which link one complementary strand to the other and enable replication.

In proteins, hydrogen bonds form between the backbone oxygens and amide hydrogens. Because of H-bonding, Alpha helix and Beta sheet is able to form in proteins. This is the secondary structure.  Hydrogen bonds also play a part in forming the tertiary structure of protein through interaction of R-groups.

Answer 3

Ok, Let me explain these:

DNA:

It is important for DNA because they are strong together, but these types of bonds can be easily broken apart, which is important for DNA replication and for RNA production.

RNA:

RNA itself does not have hydrogen bonding, but during translation of protein synthesis, you need to easily break the codon and anti-codon bond (these are just three base pairs).  If I was going to be tested on knowledge, then I would have put secondary RNA. But for the purpose of understanding  the basics, I did not put that answer in. If you want me to, I will but for now there is no need to confuse the person asking the question!

Protein=prions:

Proteins have different types of bonds within it tertiary and secondary structures like alpha and beta helixes and beta sheets. These contain hydrogen bonds.

good luck.
