  • Chapter 1 and 2 are the lengthiest chapter. Do all the previous yr questions. Learn all the techniques-PCR,southern hybridization, SDM,Sanger's. Learn thr features of vector. What is proteomics. Biotech is an easy chapter. Do some smart work. Go through previous yr ques papers u'll find most of the questions r repeated.

  • Metagenomics is the study of genetic material recovered directly from environmental samples. The broad field may also be referred to as environmental genomics, ecogenomics or community genomics.

  • Site-directed mutagenesis, also called site-specific mutagenesis or oligo nucleotide-directed mutagenesis, is a molecular biology technique often used in bio molecular engineering in which a mutation is created at a defined site in a DNA molecule.

  • A typical microarray experiment involves the hybridization of an mRNA molecule to the DNA template from which it is originated. Many DNA samples are used to construct an array. The amount of mRNA bound to each site on the array indicates the expression level of the various genes. This number may run in thousands. All the data is collected and a profile is generated for gene expression in the cell.

  • An array is an orderly arrangement of samples where matching of known and unknown DNA samples is done based on base pairing rules. An array experiment makes use of common assay systems such as microplates or standard blotting membranes. The sample spot sizes are typically less than 200 microns in diameter usually contain thousands of spots.

    Thousands of spotted samples known as probes (with known identity) are immobilized on a solid support (a microscope glass slides or silicon chips or nylon membrane). The spots can be DNA, cDNA, or oligonucleotides. These are used to determine complementary binding of the unknown sequences thus allowing parallel analysis for gene expression and gene discovery. An experiment with a single DNA chip can provide information on thousands of genes simultaneously. An orderly arrangement of the probes on the support is important as the location of each spot on the array is used for the identification of a gene.
