Chapter 24, Problem 1CONQ

Give the meanings of the following terms: genomics, functional genomics, and proteomics.

Summary Introduction

To review:

The definition of functional genomics, genomics, and proteomics.

Introduction:

The genetic material of a species consists of thousands of genes. In order to understand the phenotypic differences of two individuals, it is very important to study the genome of two organisms separately as well as together.

Explanation of Solution

The description of functional genomics, genomics, and proteomics is given below:

Genomics: It refers to the analysis of the complete genome of an individual. It integrates DNA (Deoxyribonucleic acid) sequencing methods, bioinformatics, and recombinant DNA to obtain the complete sequence of all the chromosomes.

Functional genomics: The analysis of all the genes and intervening sequences which have been obtained by sequencing methods comes under functional genomics. The goal is to obtain the functions of all these elements and analyze the ways, in which they interact with each other to result in specific phenotype. Understanding the function of centromeres as well as repetitive sequences are also included in it.

Proteomics: Proteins are a product of genes in an individual. Proteins are greater than the number of genes. Proteomics is an extensive study of the whole complement of proteins in an individual, their physiological functions, and structures.

Conclusion

Therefore, it can be concluded that genomics aim at obtaining the complete genome of an individual, functional genomics focuses on the functions of the gene and its interaction with one another, and proteomics aims to understand the structure as well as functions of all the proteins in an individual.
