Summary Introduction

To review:

The reason behind a complementary deoxyribonucleic acid (cDNA) library constructed from human brain tissue being both similar to and different from a cDNA library constructed from the human pancreatic tissue.

Introduction:

A collection of different cloned deoxyribonucleic acid (DNA) sequences from an organism is called a gene library. There are usually two types of gene library, namely: genomic library and complementary DNA (cDNA) library, which depends on the source of DNA used. A collection of clones containing cDNA molecules that are usually synthesized from messenger ribonucleic acid (mRNA) molecules in a cell of an organism is called cDNA library. It contains only the coding regions of a genomic material of an organism, unlike genomic library which contains the whole genome of an organism.
