spores germinate and form hyphae (Campbell‚ 64) Species of the genus Sordaria share a number of characteristics that are advantageous for genetic studies. They all have a short life cycle‚ usually 7-12 days‚ and are easy to grow on nutrient agar in dish cultures. All kinds of mutants are easily induced and readily obtainable with particular ascospore color mutants. These visual mutants aid in tetrad analysis‚ especially in analysis of intragenic recombination. ( Campbell 72) A common lab use

Animal testing has been an issue since the 19th century‚ it all started in the United Kingdom with a French chemist named Louis Pasteur. Even though animal testing has a lot of pros and cons it is very cruel and inhumane. Right now many animals are locked inside cages in laboratories sitting lonely and fearing that they would be chosen to practice an experiment on them. They are forced to inhale cigarettes and they can’t spit it out because their mouth is locked up and they have no movement. They

Planning Exercise Aim To investigate the effect of phosphate on cell division in root tips. Background knowledge Phosphate ions (macronutrients) are needed large amounts by plants. They are required for root growth. For the root tips cells to divide‚ mitosis has to occur. Phosphate is needed for production of ATP which provides energy for mitosis to occur. DNA replication occurs during interphase of the cell cycle. DNA is made up of nitrogen containing base‚ pentose sugar and phosphate group

growth was measured by filtering the contents using Whatman Filter paper No.1 from each of the flasks. The filter paper was washed with deionized water and then dried at 750C in a hot air oven till completely dried and was weighed in a pre-weighed Petri dish to obtain the residual fungal mass. The lowest concentration at which the fungal mycelium growth inhibited was chosen as the MIC of deltamethrin (Abraham and Silambarasan‚

used to differentiate different species of bacteria. These tests are effective in determining the characteristics of the microbe being tested. Such characteristics include citrate utilization‚ gelatin hydrolysis‚ nitrate reduction‚ etc. Biochemical testing is very important in the medical field when a patient is infected with an unknown microbe. Such testing can identify the microbe(s) and types of medications effective in treating the infection. It is also useful
