<h2>
Option (B) is Right Answer</h2>
Explanation:
(B) chromatids are attached to one another
- <em>The linkage between the sister chromatids </em>is particularly critical at centromeres because it ensures right <em>microtubule connection to the kinetochores </em>
- In eukaryotes, a centromere is a district of DNA that is responsible for the development of the imitated chromosomes into the<em> two daughter cells during mitosis and meiosis</em>
- There is one centromere on every <em>chromosome and centromeres are responsible for two major functions</em>
- In eukaryotes, a centromere is a district of DNA that is responsible for the development of the imitated chromosomes into the <em>two daughter cells during mitosis and meiosis</em>
Answer:
d. disrupt the function of protein kinases involved in cell cycle regulation.
Explanation:
Protein kinases which are useful in cell cycles have major roles in the formation of tumors. So many of these protein kinases go through mutations. Cell cycles would be unable to be stoped and tumor would keep increasing.
A lot of receptors are G protein coupled. So it is going to be really helpful to alter and make G protein receptors to be inactive. Most if these kinases go through means of phosphorylation and dephosphorylation. Targeting these would cause disruption in signal transduction in cells with cancer
<span>People who are infected with
AIDS has more tendency to acquire multiple infections because the pathogen that
causes acquired immunodeficiency
syndrome (AIDS) damages the immune system of a patient by destroying the white
blood cells that fight infection. If the CD4</span>+ T cell count below 200 cells per µL and presence of
specific diseases in association with an HIV infection are observe in an
individual, then this could be an indication of having an AIDS.
Moreover, opportunistic
infections or cancer may take advantage of a very weak immune system, an
individual can develop an influenza-like illness with signs and symptoms that
includes swollen lymph nodes, fever, rash, weight loss, diarrhea and cough.
