Umbilical cord blood is a rich source of stem cells. which possible advance in biology would most likely be a result of performing research with an individual’s banked cord blood? creation of a novel cancer cell line to test anticancer agents creation of a personalized cell replacement therapy for the donor creation of a skin graft for an unrelated burn victim creation of a culture to produce vitamin e

Ans.

Umbilical cord blood is remains in umbilical cord and in placenta after the birth of child. Cord blood is collected and banked as it contains embryonic stem cells that can be used for the treatment of various genetic and hematopoietic diseases.

Embryonic stem cells are pluoripotent cells that can differentiate into a wide range of cells with specific properties. For example, a hematopoietic stem cell of embryo can produce different types of blood cells (WBCs, RBCs, and platelets) and a mesenchymal stromal stem cell of embryo can produce cartilage, bones, and other kinds of tissue.

Thus, the correct answer is option). 'creation of a personalized cell.'

The answer is B

Explanation:

Creation of a personalized cell replacement therapy for the donor

genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring).
