Assignment 1: Biological Sciences and Model Organisms (6%)
Matriculation No.: A0101681R Name: Ramireddi Juhi Simanthika TA: (sorry couldn't catch her name)
1. When a model organism is applied for researches, it has both advantages and disadvantages as they are described for M. musculus in the laboratory manual. Please write the respective advantages and disadvantages when A. thaliana and D. rerio are used for developmental research. (4 marks)
Organisms | Advantages | Disadvantages | A. thaliana used for plant development research | 1.) Tiny Genome- Therefore it is easy to study the genes and also to manipulate the genes.2.) Short Life Cycle- Experiments conducted on the A.thaliana will have observable results fast as the development of the plant is rapid.3.) Small size-can be cultivated in a tiny space and this is vital because research areas usually have space limitations.4.) Male and female sex organs available on the same flower- vital for plant genetic mating research | 1.) Pests- Pests are easily attracted to this organism.2.) Similar Genotype- Sometimes, the genotypes of different specimens are so similar that it is hard to distinguish the corresponding difference in phenotype. | D. rerio used for animal development research | 1.) Small Size and can be bred together in high densities- Feasible to breed many D.rerio in a small space. (Research Labs have space constraints for breeding) 2.)Transparent Embryo that develops outside mother's womb - Observing organ development at various stages is much easier. 3.) Embryo resembles that of higher vertebrates4.) Rapid Development of Embryo- Experimental data can be collected within a short span of time. | 1.) Water system required- The D.rerio only thrive in water and therefore resources have to be expended
