Chapter 2, Problem 16Q

A. (a)

Summary Introduction

To determine: How many different molecules that are composed of two amino acids and are linked together by peptide bonds can be made from 20 naturally occurring amino acids.

Introduction: Proteins are made up of amino acids. Twenty-two amino acids are naturally incorporated into polypeptides and are called natural or proteogenic amino acids. Out of these, 20 amino acids are encoded by the genetic code.

(b)

Summary Introduction

To determine: How many different molecules that are composed of three amino acids and are linked together by peptide bonds can be made from 20 naturally occurring amino acids.

Introduction: Proteins are made up of amino acids. Twenty-two amino acids are naturally incorporated into polypeptides and are called natural or proteogenic amino acids. Out of these, 20 amino acids are encoded by the genetic code.

(c)

Summary Introduction

To determine: How many different molecules that are composed of four amino acids and are linked together by peptide bonds can be made from 20 naturally occurring amino acids.

Introduction: Proteins are made up of amino acids. Twenty-two amino acids are naturally incorporated into polypeptides and are called natural or proteogenic amino acids. Out of these, 20 amino acids are encoded by the genetic code.

B1.

Summary Introduction

To calculate: The weight of a given mixture consisting of one molecule each of all possible sequences of a small protein of molecular weight 4800 Daltons, if the average molecular weight of an aminoacid is given as 120 Daltons.

Introduction: Amino acids are organic compounds containing amine and carboxyl functional groups, along with a side chain (R group) specific to each amino acid. The average molecular weight of an amino acid is 110Da.

B2.

Summary Introduction

To explain: What size of the container is needed to hold the given sample.

Introduction: Amino acids are organic compounds containing amine and carboxyl functional groups, along with a side chain (R group) specific to each amino acid. The average molecular weight of an amino acid is 110Da.

C.

Summary Introduction

To explain: What does the above calculation tell about the fraction of possible proteins that are currently in use by living organisms if the average molecular weight of the protein is about 30,000 Daltons.

Introduction: Proteins are made up of amino acids. Twenty-two amino acids are naturally incorporated into polypeptides and are called natural or proteogenic amino acids. Out of these, 20 amino acids are encoded by the genetic code.

You aim to test the hypothesis that the Tbx4 and Tbx5 genes inhibit each other's expression during limb development. With access to chicken embryos and viruses capable of overexpressing Tbx4 and Tbx5, describe an experiment to investigate whether these genes suppress each other's expression in the limb buds. What results would you expect if they do repress each other? What results would you expect if they do not repress each other?
You decide to delete Fgf4 and Fgf8 specifically in the limb bud. Explain why you would not knock out these genes in the entire embryo instead.
You implant an FGF10-coated bead into the anterior flank of a chicken embryo, directly below the level of the wing bud. What is the phenotype of the resulting ectopic limb?  Briefly describe the expected expression domains of 1) Shh, 2) Tbx4, and 3) Tbx5 in the resulting ectopic limb bud.
