Twо cliniciаns interview the sаme pаtient. When they use a semi-structured prоtоcol, their diagnostic conclusions are more likely to agree than when they use an unstructured interview. This difference is best described as a difference in:

Teratomas develop from germ cells, a type of cell that gives rise to gametes. Because germ cells are not differentiated into specific cell types (as are e.g. muscle cells, skin cells, fat cells, etc.), teratomas can develop exhibiting numerous different cell types, giving them their name teratoma, Greek for “monstrous tumor”. Teratomas may be benign or cancerous. As a result of mistakes in processes of cell division, they are generally diploid, and sometimes polyploid. Consider a cell of a teratoma and a healthy human epithelial (skin) cell. Now consider the DNA and the mRNA found in both cells. For each of these (DNA and mRNA), compare and contrast what you would expect to find in both the teratoma and a healthy cell, i.e., would the DNA and the mRNA be the same, or different, or partially the same and partially different, in each cell? For your answer, consider what each of these (DNA, mRNA) accomplishes in a cell, and what its presence represents. Please explain briefly but clearly for each of these nucleic acids and provide examples or reasons. Label each of your answers 1 and 2 and write a short paragraph (a few sentences) for each. 1) DNA in teratoma vs. healthy cell 2) mRNA in teratoma vs. healthy cell Figure 1.
