Q) What is molecular complementarity? Describe it with two examples. More than one type of biological macromolecule (proteins, nucleic acids, phospholipids, carbohydrates) should be mentioned in your examples, but each of the two examples can be about only one type of biological macromolecule.

Answer #1

Question:

Answer:

In molecular biology, molecular complementarity is defining as relationship between two molecules based on lock and key interaction model.

Example: Nucleic acids: i. adenine will bind to thymine so, A and T is complementary.

ii. Cytosine is complementary to guanine.

iii. tRNA is complementary to mRNA.

Proteins: i. essential and nonessential amino acids.

ii. Enzyme and ligand interaction

iii. Antibodies and antigen

iv. Alpha and beta sheets

Carbohydrates: i. Glucose glucose bonding in cellulose

ii. glucose and fructose in sucrose.

Lipids

Lipid lipid interaction with phospholipids un trilipid layer.

Biological macromolecules such as proteins may be positively, negatively, or neutrally charged depending on what amino acids are present. Some parts of a macromolecule may be positively charged while others are negatively charged, and this can affect the conformation – the shape of the macromolecule. Changes in the conformation may affect the function of a macromolecule. Two charged macromolecules (labelled 1 and 2) have charges q1 =+3.20 × 10-19 C and q2 =+12.8 × 10-19 C. They are separated by...
