To determine: The application of FISH in obtaining the telomeric chromosomes in the G2 phase of the cell cycle.
Introduction: Fluorescent in situ hybridization or FISH is the technique, which uses fluorescent probes or radioactive elements to diagnose and detect any chromosomal abnormality. For example, cancer cells are detected by this technique. Also, other abnormalities such as aneuploidy, deletions, and duplication are detected by FISH.
Explanation of Solution
Humans are the eukaryotic diploid organisms, in which 23 pairs or 46 chromosomes are present. The telomeres are the

Note the cells are not arranged in the order in which mitosis occurs . Use the diagram to answer questions 1-5 Phases of the Cell Cycle D F 1. How can you tell which diagram(s) is/are the end of the cell division? 2. What are structures seen inside the nucleus? 3. Are the cells depicted plant or animal cells? Explain your answer.arrow_forwardDo you expect any color or labeling in onion cells? Why not? 2. Would you expect Lugol's Solution to stain onion cells? Why or why not? Finally, look at cheek cells. Can you find the nucleus? 3. What strikes you as different in terms of cell shape compared to onion cells or cork cells? Why do you think that is? Think about differences between animal and plant cells (Figure 4.4 and text on page 59 of your textbook).arrow_forward

The researchers collected the sample and made careful observations of it. The picture at right shows a microscopic image captured at 1000X its actual size. Below are some other observations made: • When DNA was isolated from the cell, it was mixed with an equal portion of histone proteins • There are no visible organelles present inside the cell • The specimen seem to die in the presence of oxygen • Able to live in conditions that mimic deep sea vents without any external food source provided Based on these observations, determine each of the following and provide a clear rationale. A) To which domain would you assign this organism? Why? B) Propose a hypothesis of how they obtain nutrients. Are these most likely autotrophs or heterotrophs? Provide a rationale.arrow_forwardhelp me with this multiple choice question please, this is molecular and cell biology Visualization of an electrophoresed agarose gel (D) Plasmid DNA cannot be visualized on an agarose gel (A) Plasmid DNA may be visualized as multiple supercoiled forms (B) Visualized plasmid DNA is always linear Ⓒ(C) Visualized plasmid DNA is always circulararrow_forward
