Chapter 6, Problem 8P
Interpretation Introduction

(a)

Interpretation:

80% divergence of two proteins from a common ancestor.

Concept introduction:

All the living organisms arise from primitive organisms. The new organisms are called descendents while the primitive organisms are called forefathers or ancestors.

Interpretation Introduction

(b)

Interpretation:

50% divergence of two proteins from a common ancestor.

Concept introduction:

The evolutionary process in which organisms from a common ancestor attainnew traits and become different from each other. The amino acid sequence gives an interpretation about the rate of divergence in different organisms.

Interpretation Introduction

(c)

Interpretation:

20% divergence of two proteins from a common ancestor.

Concept introduction:

The proteins are formed from the amino acids. The sequence of amino acids is used for evolutionary studies. It helps in detecting the ancestors of different organisms.

Interpretation Introduction

(d)

Interpretation:

10% divergence of two proteins from a common ancestor.

Concept introduction:

The descended organisms inherit many traits from their ancestors that help them in their survival. Divergence is a part of the evolutionary history of an organism. The descendants adapt to the new environment by the process of divergence.

A protein has a molecular mass of 400 kDa when measured by size-exclusion chromatography. When subjected to gel electrophoresis in the presence of sodium dodecyl sulfate (SDS), the protein gives three bands with molecular masses of 180, 160, and 60 kDa. When electrophoresis is carried out in the presence of SDS and dithiothreitol (DTT), three bands again form, this time with molecular masses of 160, 90, and 60 kDa. How many subunits does the protein have, and what is the molecular mass of each? four subunits: 180, 160, 90, and 60 kDa three subunits: 180, 160, and 60 kDa three subunits: 160, 90, and 60 kDa four subunits: 160, 90, 90, and 60 kDa Correct Answer
