https://www.youtube.com/watch?v=TUKBV6nLNIM Key Notes: Fungi are any of a group of spore-producing organisms feeding on organic matter, including molds, yeast, mushrooms, and toadstools. Roles of fungi: decomposers, parasites, mutualists Plant cell walls are made of cellulose. Fungi cell walls are made of chitin. Fungi are closely related to animals than plants. Fungi are absorptive chemoheterotrophs meaning … Continue reading Introduction To Fungi

The Polymerase Chain Reaction (PCR)

The polymerase chain reaction (PCR) is used to produce many copies of a specific sequence of DNA.Source: OpenStax Microbiology OpenStax Microbiology Most methods of DNA analysis, such as restriction enzyme digestion and agarose gel electrophoresis, or DNA sequencing require large amounts of a specific DNA fragment. In the past, large amounts of DNA were produced … Continue reading The Polymerase Chain Reaction (PCR)

The Alkylating Agents

(a) Alkylating agents replace hydrogen atoms with alkyl groups. Here, guanine is alkylated, resulting in its hydrogen bonding with thymine, instead of cytosine. (b) The chemical structures of several alkylating agents.Source: OpenStax Microbiology OpenStax Microbiology The alkylating agents are a group of strong disinfecting chemicals that act by replacing a hydrogen atom within a molecule … Continue reading The Alkylating Agents
