organism‚ organ or cell is called growth”‚ which includes increase in mass weight or volume of living organism‚ it leads to development in plants. REGION OF GROWTH: Growth region is located at extreme apices of root‚ stem‚ leaf where we make out meristematic tissue. In addition to above‚ the region where intercalary and lateral meristem is present is also considered as growth region. PHASES OF GROWTH: Growth is a complex process where the dividing cell pass through three phases: 1. Cell division 2

Cloning and stem cell research have come a long way in the past few decades. Expert scientist have the capability of making an exact‚ physical copy of a living body as well using stem cells to cure genetic diseases. Although these two topics are quite common now‚ they weren’t well known when Mary Shelley’s Frankenstein fictional novel was initially published. The idea of cloning may have been new and debatable at the time‚ but Shelley took the idea with a more fictional perspective. With this novel

Biotechnology‚ particularly genetic engineering‚ is already a beneficial resource‚ employed in medicine. “Genetic engineering is the human altering of the genetic material of living cells to make them capable of producing new substances or performing new functions” (Gale‚ 2005). It has the potential to improve our health and well-being significantly‚ revolutionize our manner of living‚ help us to conserve limited resources‚ and produce

Nutritional problems as well as over hydration are caused by lower-than-normal hematocrit levels. Bacterial infection may lower your hematocrit levels. 2)Compare the development of lymphocytes with the development of the other formed elements. Lymphocytes and other formed elements are developed from pluripotent stem cells

Bone marrow transplants are given to treat malignant and nonmalignant diseases such as leukemia‚ lymphoma‚ marrow failure also known as aplastic anemia‚ metabolic disorders‚ HIV‚ Inherited red cell disorders (Gratwohl‚ 2006). Bone marrow can be taken from umbilical cord blood‚ peripheral blood stem cells and from bone marrow itself from various donors. They can be obtained from either autologous which is from the recipient themselves or from an allogeneic donor which is from someone else either

1) What are the technical challenges for cloning a mammal organism? Include the following terms in your answer: cell determination‚ cell differentiation‚ and nuclear reprogramming. Cloning is producing a cell line or culture all whose members contain identical copies of a particular nucleotide sequence; an essential element in genetic engineering (Raven et al‚ G-5). Lack of imprinting; genes that are imprinted are expressed differently‚ the original parent in which the gene was taken from is the
