A.

Summary Introduction

To explain: Cytotoxic T cells having heterozygous d-type/k-type class I MHC can lyse infected d-type cells and k-type cells or not.

Concept introduction: T cells and B cells are lymphocytes of the immune system which helps to elicit an immune response against an invading pathogen. T cells are antigen-presenting cells (APC). There are three types of T cells: Cytotoxic T cells, Helper T cells and memory T cells. There are other minor types of T cells like natural killer T cell, γδ T cells and many more. The main function of cytotoxic T cells represented as TC have T-cell receptors on the surface of their plasma membrane that has the capacity to recognize specific antigens that can be even nuclear proteins of the pathogen.

Summary Introduction

To explain: Nude mouse which has cytotoxic T cells having heterozygous d-type /k-type  was given a thymus from an d-type donor will lyse d-type infected cells or k-type infected cells or neither.

You aim to test the hypothesis that the Tbx4 and Tbx5 genes inhibit each other's expression during limb development. With access to chicken embryos and viruses capable of overexpressing Tbx4 and Tbx5, describe an experiment to investigate whether these genes suppress each other's expression in the limb buds. What results would you expect if they do repress each other? What results would you expect if they do not repress each other?
You decide to delete Fgf4 and Fgf8 specifically in the limb bud. Explain why you would not knock out these genes in the entire embryo instead.
You implant an FGF10-coated bead into the anterior flank of a chicken embryo, directly below the level of the wing bud. What is the phenotype of the resulting ectopic limb?  Briefly describe the expected expression domains of 1) Shh, 2) Tbx4, and 3) Tbx5 in the resulting ectopic limb bud.
