Abstract

The analysis and interpretation of experimental data are the crucial steps in biological research. Multidisciplinary methods through coalition of biological data with statistics are essential for this. Biostatistics and bioinformatics are the platforms that provide support for examination and understanding of the biological information. This chapter focuses on statistical and bioinformatics tools and techniques used to analyze data related to microbial ecology and molecular biology with respect to analysis of nucleotide sequences. Stepwise description of mining, analyses, and interpretation of data is provided in this chapter. This will help to determine the most appropriate method to be applied for a particular analysis to draw the best acceptable inference. In addition, this chapter also enlists the various online available databases and associated tools used to collect and compare biological data and information. Taken altogether, this chapter will enlighten students and researchers with the knowledge on multifarious analytical methods, which will aid better understanding and interpretation of their scientific findings.

1.1. Aim of the chapter

This chapter aims to describe the tools and the techniques that are being applied globally for analysis and assessment of biological data. The chapter has been divided into three sections (nucleic acid: 1.2 and 1.3; microbial ecology: 1.4; bio statistics: 1.5).

(1) Section I deals with the bioinformatics methods applied for molecular analyses of nucleic acids. (2) Section II deals with the statistical formulae used to interpret microbial ecological data. (3) Section III describes statistical methods used to compare the biological observations to draw significant conclusions. Care has been taken to present the methods in a stepwise manner with examples for better understanding.

1.2. DNA sequencing

DNA sequencing is the process of determining the order of nucleotides within a DNA molecule. There are two methods of DNA sequencing: Maxam–Gilbert sequencing and Sanger sequencing. The former is a chemical method that chemically modifies the DNA nucleotides and subsequently cleaves the DNA backbone at the sites neighboring to the modified nucleotides [1]. However, due to technical complexity and use of hazardous chemicals, this method is not currently used for standard molecular biology.

Sanger sequencing is the method of DNA sequencing in which dideoxynucleotide phosphates (ddNTPs) are incorporated by DNA polymerase during in vitro DNA replication. Modified ddNTPs terminate DNA strand elongation since they lack a 3′-OH group required for the formation of a phosphodiester bond between two nucleotides, causing DNA polymerase to cease the extension of DNA. Therefore, this is called dye-terminator sequencing. Each of the four ddNTPs (where N = A/T/G/C) is labeled with fluorescent dyes that emit light at different wavelengths and therefore can be captured in the form of colored peaks called a chromatogram.

The nucleotide bases of DNA obtained from a chromatogram are converted to text-based FASTA format using the Applied Biosystems to FASTA converter database (www.dn...
