Chapter 3, Problem 1P
Summary Introduction

To examine:  Whether the statement “Each strand in a β sheet is a helix with two amino acids per turn” is true or false.

Introduction:

Proteins consist of a chain of amino acids called polypeptide. There are 20 different amino acids in proteins which are coded by organisms’ DNA. Protein structure is considered to contain four structural level: primary, secondary, tertiary structure, and quaternary structures.

Expert Solution & Answer

Answer to Problem 1P

Correct answer: The statement is true.

Explanation of Solution

The β-sheet is a secondary structure of the protein. This is formed by hydrogen bonding between the N-H and C=O groups in the polypeptide backbone. It can be arranged in a helical pattern to form helix. The axial distance between two amino acids in beta sheet is 3.5 Å. There are two amino acids repeat unit which give β strand a 7 Å pitch.

Hence, the statement is true.

Humans consider themselves amazingly clever and innovative, constantly developing "new" ways of altering the world around us. As material consumption has increased, many have turned to the ideas of recycling and reuse as a means to minimize some negative aspects of our modern consumerism. Mother Nature though is the ultimate innovator and, more importantly, the ultimate recycler.

Alleles at the P locus control seed color. Plants which are pp have white seeds, white flowers and no pigment in vegetative parts. Plants which are P_ have black seeds, purple flowers and may have varying degrees of pigment on stems and leaves. Seed color can be assessed, visually, based on if the seed is white or not white A gene for mold resistance has been reported and we want to determine its inheritance and whether it is linked to P. For the purposes of this exercise, we will assume that resistance is controlled by a single locus M, and M_ plants are resistant and mm plants are susceptible.  Resistance can be measured, under greenhouse conditions, 2 weeks after planting, by injecting each seedling with a spore suspension. After two weeks, the seedlings can be rated as resistant or susceptible, based on whether or not tissue is actively sporulating. For this exercise we will use seed and data from the F10 generation of a recombinant inbred population produced using single seed…
