Subtractive hybridization between two complementary DNA (cDNA) libraries is a powerful tool for identifying differentially

In this chapter, we will describe microarray chips that host nucleic acid probes, which are the most commonly used type of microarrays. Science in this field is mostly data-driven, where

Mike Scherfner,Torsten Vollandare present in the precursor mRNA (pre-mRNA) molecule and subsequent ligation of the flanking, functional sequences (i.e., exons). Pre-mRNA splicing is thus a critical step in the long chain of events required for the expression of a large number of eukaryotic genes. In a number of instances, the sp

Ribonucleotide reductases belong to a heterogeneous family of enzymes, containing at least three discernible classes. They differ in com

The RNA subunit is able to recognize and cleave tRNA precursors (ptRNAs) at the correct site when the reaction is carried out in buffers that contain a high concentration of Mg. ions. This RNA, by itself, behaves as a true enzyme. When present in small amounts

Since then, the Rb gene product (pRb) has established itself as a protein of central importance to those researchers interested in the regulation of cellular proliferation and the mechanisms of cellular transformation.

Mike Scherfner,Torsten Volland there are several well-documented examples of regulatory proteins, such as the lambda repressor. The intimate molecular mechanism of the interaction between these prokaryotic regulatory proteins and the DNA double helix is known in great detail. However, it is not yet clear how this interaction mod
