2.) One experimental tool used in the biological research and in clinical settings is called Fluorescent Activated Cell Sorting (FACS) or cell cytometry. For example, a cell membrane permeable (or nonpolar) chemical called Hoescht 33342 dye will specifically label DNA. Interpret the graph (Figure 17-4) that illustrates normal cells that have been labeled with Hoescht 33342 dye, and assign which phase(s) of the cell cycle (G1, S, G2, or M) corresponds to the fluorescence intensity. Justify your answers. 1 relative fluorescence per cell Figure 17-4 Analysis of Hoechst 33342 fluorescence in a population of cells sorted in a flow cytometer (Problem 17-15). number of cells

Question in photo

The microscope image above shows the human chromosomes from a white blood cell.  To create the image,  researchers put cells in culture under conditions that encourage the cells to divide.  They bathed the cells in a hypotonic (low salt) solution, which caused the cells to swell until their plasma membrane burst open.   They "squashed"  the chromosomes to spread them out, and stained them with a dye to make them visible under the microscope.  Human chromosomes are numbered from longest (1) to shortest (22) plus the sex chromosomes X and Y.  In the image chromosome 1 is about 7 micrometers. Answer the following questions. 1) What word(s) in the description above indicates that the chromosomes are not from a cell undergoing meiosis? 2) Based on the size, shape and appearance of the chromosomes in the image, in what cell cycle stage was the cell that the chromosomes came from?   How can you tell? 3) Does the image suggest that centromere sequences are always located in the middle of a…

Please help me with the multiple choice question below - it is based on genomics/developmental biology.

Give only typing answer with explanation and conclusion  Your analysis has identified that this new organism has same chromosomal structure as that of eukaryotes on earth. However, the average length of linker DNA of the new organism is 100 bp. If the haploid genome of the new organism has a size 6 billion bp, how many nucleosomes will be in this new organism?

Don't have to explain, just give me the letter of the correct answer

Draw and label G1 and G2 stages of interphase and each stage of mitosis (in order) for a cell that has two large and two small chromosomes, 2n=4. For unreplicated chromosome draw a line ( / ) and for replicated chromosome draw an X. Since we are focusing on the DNA, you can skip drawing the nuclear membrane or spindle fibers. For simplicity, do not indicate that the chromosomes are decondensed chromatin during interphase.  Mark and label a place on one of the large chromosomes with the dominant allele of the “A” gene and put the recessive allele “a” on the other homolog. Mark and label a place on one of the small chromosomes with allele “B” and put the recessive allele “b” on the other homolog.
