1. The termites get their nourishment form the cellulose, which is the material that makes up the wood. 2. The three domains shown in the video along with the tupe sof cells discussed in the video are: 3. It is difficult to identify prokaryotes through a microscope because their size is too small. They are identified by sorting their genome. 4. The number of copies produced after PCR cycles can be calculated as follows: 2n where n= number of cycles So, after 30 cycles, 230= 1.02 X 109 copies of DNA will be produced. 5. In Agarose gel electrophoreses, the DNA move towards the positively charged terminal (Anode)because the phosphate group of the DNA is negatively charged. The wells are near the negatively charged terminal (Cathode). 6. When exposed to electric current in a gel electrophoreses, the smaller strands of the DNA move more quickly as their Molecular weight is lower as compared to the larger fragments. SO, they will experience less resistance in the gel. Thus, this movement results in fragments arranged in order of size. 7. Dr. Nelson found a surprising fact about Thermotoga that inspite being belong to the Bacteria Domain ,thermotoga shows many similarities with the Archae domain. 8. This shows that thermotoga has the closest relatedness with the first life on the earth. It also shows that it is the deepest lineage of the bacteria. 9. Thermotoga belong to the Bacterial domain of life. 10. The rRNA gene sequences are as means of determining phylogenetic relatedness in micororganisms because through variation in rRNA sequence(divergence), we can distinguish organisms on the species level and trace the evolutionary relationships. 11. The viruses are not considered in the phylogenetic trees because they don\'t carry the same complement of genes that we can find on other organisms. 12. Some organisms pointed out by Tom in the video are Proteobacter, E-coli, Nocardia. 13. Eukaryotes, Chordates, Arthropods, Bacteria. 14. Culturing of micoroorganisms is useful to increase the number of microorganisms. It is a method of multiplying the numebr of microorgainsms by giving them a media to grow and divide. 15. Norm said \"Microbial world is most of the biology\" because the microorganisms play a major role in all the various activities of the life. They help in maintaining the chemistry of biosphere. Also, if we remove all the microorganisms from the world, our life will be disrupted and if we remove all animals then microorganisms adapt themselves for those condition, life will sustain. 16. Functions of microorganisms in the environment: Solution 1. The termites get their nourishment form the cellulose, which is the material that makes up the wood. 2. The three domains shown in the video along with the tupe sof cells discussed in the video are: 3. It is difficult to identify prokaryotes through a microscope because their size is too small.
