A model of stem cell differentiation is shown in the image. Examine the image. Describe the role of nucleic acids in the differentiation model shown here. Select 2 descriptions that apply.
Responses
A Only certain genes are activated in stem cells to become differentiated.Only certain genes are activated in stem cells to become differentiated.
B Deleting the genes that are not utilized in a cell conserves energy for the stem cells.Deleting the genes that are not utilized in a cell conserves energy for the stem cells.
C The activation of specific portions of the genome creates a cell with a specialized function.The activation of specific portions of the genome creates a cell with a specialized function.
D Additional DNA is inserted into a cell to create a specialized cell, such as the neuron shown here.Additional DNA is inserted into a cell to create a specialized cell, such as the neuron shown here.
E Creating a differentiated cell requires that the majority of the genome within the stem cell to become activated.
A and C are the correct descriptions that apply in this case.
A) Only certain genes are activated in stem cells to become differentiated. This is true as stem cells have the ability to differentiate into various cell types, and the activation of specific genes determines the fate of the stem cell and the type of cell it will differentiate into.
C) The activation of specific portions of the genome creates a cell with a specialized function. This is also true as the activation of specific genes or portions of the genome leads to the expression of proteins and other molecules that are necessary for the specialized function of a particular cell type.
