The figure below shows differential methylation patterns for various genes in samples of 2 embryonic stem cells (ES), 5 induced pluripotent stem cells (iPSC), and 4 somatic cells. Some genes were not successfully reprogrammed. Use this figure to answer the following question. which of the following is the most accurate statement about the figure? - The genes in regions A, B, and C, all seem to be expressed in embryonic stem cells, and are silenced primarily in adult cells. - The genes in regions A, B ,and C are active in embryonic stem cells. - HDACs may be acting on genes in regions A, B , and C in the ES cells. - All of the iPSC cells are safe to use in therapy.

Gene Interactions

When the expression of a single trait is influenced by two or more different non-allelic genes, it is termed as genetic interaction. According to Mendel's law of inheritance, each gene functions in its own way and does not depend on the function of another gene, i.e., a single gene controls each of seven characteristics considered, but the complex contribution of many different genes determine many traits of an organism.

Gene Expression

Gene expression is a process by which the instructions present in deoxyribonucleic acid (DNA) are converted into useful molecules such as proteins, and functional messenger ribonucleic (mRNA) molecules in the case of non-protein-coding genes.
