What is a microbiology course? Microbiology courses are educational programs that focus on the study of microorganisms—tiny living things that cannot be seen with the naked eye. These include bacteria, viruses, fungi, protozoa, and algae. These microbiology courses teach the following: 1) How do microorganisms survive and grow?2) How do they cause diseases?3) How are … Read more
Introduction The trp operon is a repressible operon. Many of the bacteria need amino acids to survive and are able to synthesize many of them. For example, bacteria such as Escherichia coli, i.e., E. coli, can either ingest tryptophan (one such amino acid) from the environment or synthesize it using enzymes that are encoded by … Read more
Introduction Genetic methylation test, also known as DNA methylation test. Epigenetics looks at how certain changes can switch genes on or off without disturbing DNA sequence itself. One of the main ways this happens in mammals is through DNA methylation. Basically, a methyl group attaches to the fifth carbon of a cytosine, but only if … Read more
