Question

Gigantic Bacteria, Epulopiscium fishelsoni. It mentioned that in early morning, nucleoids contain highly condensed DNA in elongate, chromosome-like structures which are physically separated from the general cytoplasm. I want to talk about the gene that makes the nucleoids contain highly condensed DNA in elongate only in early morning. My question is why not any time of the day or night. My professor told me I can talk about this phenotype but I need to define how I would experimentally measure the phenotype that I mentioned. Also he told me to think about which protein in the cell you would like to tag. I told him that I want to tag histone like protein such as Hfq. He replied saying And when you choose a final combination for your phenotypic measurement, describe the genetic proposal and experiment how you will create such a measurement in order to find which phenotype is responsible for that. There is no correct answer but I need to show an experiment to measure the phenotype. Please help me with this.

Explanation / Answer

Epulopiscium fishelsoni is a Gram-positive bacteria lives in symbiotic relationship with surgeonfish. This bacteria depends upon the activity of surgeonfish. During daytime or early morning, bacteria restraining the pH from surgeonfish gut, but in nights or dark phase, bacteria finishes it cell of reproduction and moves in the mode of inactivation. This results in nucleoids with highly condensed DNA early morning.

The phenotypic ratio shows the relationship between the phenotypic characters and how frequently they occur in particular organism. This ratio can be noticed by simple observation which after can be calculated by punnet squares. This all calculation will give the incomplete dominance. Thus phenotypic ratio gives the the relationship between the physical trait.
