Answer:
Both differentiated cells and sex cells generally do not undergo mitosis past a certain phase of development. These differentiated cells include neurons, myocytes (muscle cells), keratinocytes (skin cells), and most blood cells, including B-cells, T-cells, and red blood cells.
Explanation:
Answer:
A transverse section is a cross-sectional part that is achieved by cutting the body or any part of the body structure in real or with help of imaging techniques in a horizontal plane. That plane crisscrosses the longitudinal axis at a 90-degree angle.
Explanation:
A cross section obtained by slicing, actually or through imaging techniques, the body or any part of the body structure, in a horizontal plane, i.e., a plane that intersects the longitudinal axis at a right angle. Because actual sectioning in the transverse plane results in inferior and superior portions, an anatomic transverse section may be a two-dimensional view of the cut surface on the inferior aspect of the superior portion, or of the superior aspect of the inferior portion. By convention, in medical imaging transverse sections usually demonstrate the form
Options are not provided in the question. The complete question is as following:
The role that p53 protein plays in suppressing inappropriate progression through the cell cycle depends on all of the following EXCEPT _______.
A) p53 indirectly blocks G1 to S transition in the cell cycle
B) p53 activates transcription of WAF1
C) p53 stability increases in the presence of unrepaired DNA lesions
D) the ability of p53 to bind DNA lesions
Answer: D) the ability of p53 to bind DNA lesions
Explanation:
The activities of the protein p53 are dependent on its binding DNA. Specific post-translational modifications to the p53 protein are important for efficient sequence-specific binding and transcription activities. Non-sequence-specific DNA binding can involve a broad range of p53 proteins and predominate as more serious DNA damage or greater induction of p53 protein. P53 Protein is not strictly essential for sensing and repairing DNA damage. Alternatively, p53 protein can control an apoptosis checkpoint by competing with DNA repair proteins for non-sequence-specific binding in the DNA duplex to exposed single-stranded regions.
Hence, while suppresing inappropriate progression through the cell cycle protein p53 does not bind to DNA lesions.
Hence, the correct option is D.

They are genetically and reproductively isolated. For the mule the specific isolation mechanism is termed as "Hybrid Inviability", where the postzygotic isolating mechanism prevents the hybrid from passing on their genes. A zygote may form with the sperm and egg, but the embryo will dies after a few cell divisions. The genetic information from male and female parents is insufficient to carry the organism through morphogenesis. *There are rare documented cases of a mule producing a viable offspring.
