6 0

Answer:

B.

Explanation:

Flourescent insitu hybridization-This technique permits the direct analysis of sequences of DNA or RNA in tissues

-Through this technique various chromosomal abnormalities can be determined as it focuses on that part of the DNA for which a complementary probe has been used.

-The method involves the denaturation of DNA  in a tissue section followed by the application of a labeled probe which is complementary to the sequence of  interest.

A biologist examines a series of cells and counts 160 cells in interphase, 20 cells in prophase, 6 cells in prometaphase, 2 cell
Marrrta [24]

Answer:

M phase: 4.8 hr

Prophase: 2.4 hr

Prometaphase: 0.72 hr

Metaphase: 0.24 hr

Anaphase: 0.84 hr

Telophase: 0.6 hr

Explanation:

Mitosis, also known as M phase, is the process of nuclear division after interphase, which is followed by cytoplasmic division via cytokinesis. Mitosis can be subdivided into the following phases: Prophase,  Prometaphase, Metaphase, Anaphase, and Telophase. In this case, 160 cells are in interphase (for a total of 200 cells), thereby 40 cells are in mitosis >> 200 - 160 = 40 cells. Since the complete cell cycle requires 24 hours, it is possible to calculate the average duration of each phase:

M phase: 40/200 = 0.2 x 24 hr = 4.8 hr

Prophase: 20/200 = 0.1 x 24 hr = 2.4 hr

Prometaphase: 6/200 = 0.030 x 24 hr = 0.72 hr

Metaphase: 2/200 = 0.01 x 24 hr = 0.24 hr

Anaphase: 7/200 = 0.035 x 24 hr = 0.84 hr

Telophase: 5/200 = 0.025 x 24 hr = 0.6 hr
