To answer:
The discovery of over 30 new species of bacteria that are thriving in between the human teeth and gums could not be cultured in the lab. These species cannot be able to view under any kind of microscopes. How the researchers could understand or conclude that they had discovered new species.
Introduction:
Microscope is an instrument used to view the magnified image of an object. It is used in analyzing the morphological features of the microbes.
The bacteria can be grown in a laboratory by using the proper medium in order to distinguish them based on the
To answer:
The presence of the nucleus in the cells couldn’t be examined by the microbiologists, how they determined that they were prokaryotic organisms and not eukaryotic organisms.
Microscope is an instrument used to view the magnified image of an object. It is used in analyzing the morphological features of the microbes.
The bacteria can be grown in a laboratory by using the proper medium in order to distinguish them based on the chemical reaction towards the environment.

How are Eukaryotic cells different than Prokaryotic cells, in terms of evolution which form of the cell might have came first? How do Eukaryotic cells become malignant (cancerous)?arrow_forwardWhat are the roles of DNA and proteins inside of the cell? What are the building blocks or molecular components of the DNA and proteins? How are proteins produced within the cell? What connection is there between DNA, proteins, and the cell cycle? What is the relationship between DNA, proteins, and Cancer?arrow_forwardWhy cells go through various types of cell division and how eukaryotic cells control cell growth through the cell cycle control system?arrow_forward

- Molecular Biology Question You are working to characterize a novel protein in mice. Analysis shows that high levels of the primary transcript that codes for this protein are found in tissue from the brain, muscle, liver, and pancreas. However, an antibody that recognizes the C-terminal portion of the protein indicates that the protein is present in brain, muscle, and liver, but not in the pancreas. What is the most likely explanation for this result?arrow_forwardMolecular Biology Explain/discuss how “slow stop” and “quick/fast stop” mutants wereused to identify different protein involved in DNA replication in E. coli.arrow_forwardMolecular Biology Question A gene that codes for a protein was removed from a eukaryotic cell and inserted into a prokaryotic cell. Although the gene was successfully transcribed and translated, it produced a different protein than it produced in the eukaryotic cell. What is the most likely explanation?arrow_forward
