Chapter 21, Problem 1TY

Summary Introduction

Introduction: Proteins are important biomolecules encoded by the genes. They play role in the metabolism of the organism. Structural proteins and functional proteins are the two types of proteins. Due to advances in technology, the entire collection of the proteins produced by the organism can be maintained in the form of a library for further use in research.

Answer to Problem 1TY

Correct answer: The entire collection of proteins produced by the cell or organism is called proteome. Hence, the correct answer is option c.

Explanation of Solution

Reason for correct answer:

Every cell has different proteome based on the type of function it performs and the size of the cell. Eukaryotic cells have larger proteome than prokaryotic cells. The proteome of an organism includes all the proteins synthesized in an organism.

Option c. is given as “proteome”.

Proteome refers to the entire proteins expressed by a cell or organism. Hence, the correct answer is option c.

Reasons for the incorrect answer:

Option a. is given as, “genome”.

The genome is the complete set of genes of an organism. Hence, option a. is incorrect.

Option b. is given as, “bioinformatics”.

Bioinformatics is the interdisciplinary study of biological problems to analyze and interpret them. Hence, option b. is incorrect.

Option d. is given as, “gene family”.

A gene family is the set of all genes that are evolved from a single gene. Hence, option d. is incorrect.

Option e. is given as, “protein family”.

A protein family is the set of all proteins that are evolved from the single gene. Hence, option e. is incorrect.

Hence, the options a., b., d., and e. are incorrect.

Conclusion

The entire collection of proteins produced by an organism or a cell is referred to as a proteome.
