Name: Alexis Vick Drawer/Group #: 12 PS ID #: 1059363 Three digit mutant code: 458 BIOL 3311 Fall 2014 Lab Section: 20091/Tu4 Date: 09/29/14 TA Instructor Name: Laura Montier Drosophila Melanogaster: Decapentaplegic gene The fruit fly, Drosophila Melanogaster, has been used for years as a model for genetics. The flies are small and easy to maintain in a lab, cost-efficient, and have a quick life cycle, all qualities that make this a prime organism to utilize for genetic…

three germ layers which later develop into structures of the body. It is initiated when cells move through an opening in the epiblast, called the primitive streak, to form the three layers. These three layers include the ectoderm, mesoderm, and the endoderm. The mesoderm layer gives rise to the formation of the heart and the vessels found within the body.…

Your Inner Fish by Neil Shubin Chapter Questions Chapter 1 – Finding Your Inner Fish 1. Explain why the author and his colleagues chose to focus on 375 million year old rocks in their search for fossils. Be sure to include the types of rocks and their location during their paleontology work in 2004. The author and his colleagues chose to focus on 375 Million Years as it was a period when the transformation took place from fish to fish with limb. The fish without characteristics of…

by mitosis while in undifferentiated state. Embryonic stem cells are stem cells derived from the undifferentiated inner mass cells of a human embryo, also due to them being pluripotent, they can differentiate into all derivatives of the ectoderm, endoderm and mesoderm. The induced pluripotent stem cell is the immature cell that is generated from an adult cell and regained the capacity to differentiate into any type of cell in the…

Sickle Cell Anemia Sickle cell anemia is an inherited disorder that allows for some treatment, however the average life expectancy of a patient will Sickle cell anemia is only 30 years. An inherited gene causes the hemoglobin in the blood to become misshaped. Hemoglobin is the part of the red blood cells (RBC) that carries the oxygen to all of the body’s tissues and organs. This leads to inadequate amounts of oxygen to be carried on the hemoglobin, thus resulting in insufficient oxygenation for…

It is so-called (ovary) germ cell tumors. The meaning of teras in Greek is a monster. Teratoma might occur in female and male reproductive systems because germ cells usually form the ova or eggs. It typically has three components that are endoderm, mesoderm, and ectoderm; these arise from totipotential cells (embryonic cells). Moreover, teratoma range from benign, well-differentiated (mature), and malignant (immature), but a well differentiated teratoma is by far the most common in male and…

Stages of pregnancy Weeks 1-3: The female hormone oestrogen will trigger a women’s uterus so it forms a thick blood-rich lining of tissue. The other female hormone progesterone will begin to prepare the uterus so it can support a fertilised egg and accommodate the growing baby over the next few months. During this time, the woman’s ovaries will also ripen the eggs in follicles (sacs filled with fluid). Ovulation This is a part of the menstrual cycle where the woman’s ovaries release an…
