five-kingdom system. New advances in genetic and molecular sciences have allowed for classification based on information such as base composition‚ nucleic acid hybridization‚ and amino acid sequences. The two main molecular methods to identify microbes are by the comparison of 1) DNA and RNA sequences (nucleic acid hybridization) and 2) of amino acid sequences of a protein or proteins (amino acid sequences). Nucleic acid hybridization‚ a part of the field molecular genetics‚ is used to identify related DNA

(b) Explain each of the following in terms of the properties of water. You are not limited to the three properties discussed in part (a): • • • the role of water as a medium for the metabolic processes of cells the ability of water to moderate temperature within living organisms and in organisms’ environments the movement of water from the roots to

Distinguish genetic drift from gene flow in terms of how they occur and their implications for future genetic variation in a population. Genetic drift‚ defined as the process in which chance events cause unpredictable fluctuations in allele frequencies from one generation to the next‚ can increase or decrease variability within particularly small populations. Certain genotype/phenotype frequencies‚ for example‚ may be reduced or completely eliminated through chance events. Examples of genetic drift might

ROLE OF BACTERIOPHAGES IN GENETICS AND MOLECULAR BIOLOGY INTRODUCTION AND DISCOVERY: A bacteriophage is any one of a number of viruses that infect bacteria. Bacteriophages are among the most common biological entities on Earth. The term is commonly used in its shortened form‚ phage.Typically; bacteriophages consist of an outer protein capsid‚ enclosing genetic material. The genetic material can be ssRNA‚ dsRNA‚ ssDNA‚ or dsDNA along with either circular or linear arrangement. Bacteriophages are

forming the backbone of RNA / DNA. 1A. Typical DNA Molecule DNA is a complex molecule that is found in all living organisms. Constructing DNA models is a great way to learn about DNA structure‚ function and replication. DNA contains the genetic information for the reproduction of life. Its structure is that of a twisted double helix that is composed of long strands of alternating sugars and phosphate groups‚ as well as nitrogenous bases (adenine‚ thymine‚ guanine and cytosine). The basic

Cells are not smaller that 0.1 um because within the cell all the necessary components have to take place‚ cellular metabolism‚ reproduction‚ photosynthesis and there has to be a sufficient amount of space for that to
