Structure of $tRNA$ is single helix. $tRNA$ is a type of RNA molecule that helps decode $mRNA$ sequence into a protein. $tRNA$ functions at specific sites in the ribosome during translation, which is a process that synthesizes a protein from an $mRNA$ molecule.

Through X-ray crystallographic methods, it was determined that the diameter of the double helix is around 2 nm. Also, the structure repeats itself after every 3.4 nm.

The separation of two DNA stands by heating is called denaturation. The intermolecular hydrogen bonds and disulfde linkages break.

Globular Proteins have three dimensional folded structure. These are cross linked proteins, soluble in water.
Globular Proteins are present in blood, eggs and milk.

Globular Proteins have three dimensional folded structure.
These are cross linked protein.
They are Soluble in water.
Fibrous Proteins are linear condensation polymers.
They are Insoluble in water.
These are held together by intermolecular hydrogen bond.

The secondary structure of a protein refers to either of $\alpha$-helical back bone or $\beta$-sheet.

Myoglobin or haemoglobin is a globular protein.

 Globular proteins are present in egg albumin, haemoglobin, myoglobin, insulin, serum globulins in blood, and many enzymes.

Proteins are linear polymers formed by linking the -carboxyl group of one amino acid to the -amino group of another amino acid with a peptide bond.

Proline is the only proteinogenic amino acid whose side-group links to the -amino group and, thus, is also the only proteinogenic amino acid containing a secondary amine at this position.
