Chapter 2, Problem 15P

Interpretation Introduction

(a)

Interpretation:

The length of tropomyosin needs to be determined.

Concept introduction:

Amino acids are organic compounds containing amino as well as carboxylic acid groups. These groups are common in all amino acids. The difference in all amino acids is different R groups. The general representation of an amino acid is as follows:

$H_{2}N-CH\left(R\right)-COOH$

Here, R group is different for different amino acids. This group can be acidic, basic or neutral.

Interpretation Introduction

(b)

Interpretation:

For the motif, longest dimension needs to be determined.

Concept introduction:

The hairpin loop is formed when 2 regions having the same strands but complementary in the sequence of nucleotide results in base pairing to from a double helix ending in an unpaired loop.
