The correct answer is E), some of the others are close so if I missed one I am sorry.
The mono- clonal antibody that forms Herceptin was isolated by inoculating mice with cells expressing excess levels of human HER2 protein, followed by immunization of the murine antibody.
A DNA probe from the human HER2 gene was then used to discover HER2 gene amplification in human breast cancer. The process is known as recombinant DNA technique .
HER2 plays an important role in the signaling network that drives cell proliferation. Herceptin is believed to block intracellular signaling pathways. By attenuating the signal transduction downstream, Herceptin may promote apoptosis and arrest cell proliferation. Herceptin is the brand name of a medicine called trastuzumab. some common uses of Herceptin are they are used in treatment of breast cancer, esophageal cancer and stomach cancer.

In a process called <u>Synapsis</u>, paired homologous chromosomes align randomly at the cell equator. This occurs during stage <u>prophase I</u> of cell division.
Synapsis refers to the pairing of the homologous chromosomes in the meiosis occuring in the reproductive cells. Meiosis I is divided into four phases called the prophase I, metaphase I, anaphase I and the telophase I. Prophase I is the longest phase of meiosis which is further divided into leptotene, zygotene, pachytene, diplotene and diakinesis.
During the zygotene of meiosis I, the paring of the homologous chromosomes called the synapsis takesplace which is facilitated by the protein structure called the synaptonemal complex. The paired chromosomes are called the bivalents. This facilitates the homologous recombination.
