This model shows the process of protein synthesis. The proteins a cell makes determines the job it will do, its identity. All cells
contain the entire genome of DNA. However, cells are vastly different and perform different functions. Using the model, explain how
RNA is involved in cell differentiation. Choose ALL that apply.
es.)
A)
The cell only makes RNA for the genes it will use.
B)
Transcription factors determine which genes will be transcribed into RNA.
mRNA can be modified to code for different proteins using introns and
exons
D)
The cell decides which part of the RNA it will use and deletes the rest of it.
E)
The only mRNA that is read at the ribosome is the kind that matched the
cell type.

Which of the following describes a negative feedback loop? when the heart rate is too high, the body sends hormones that continually increase the heart rate higher. when a pregnant woman is in labor, the body sends hormones that increase the intensity of contractions, which then increases the secretion of the same hormones. when blood sugar is too low, the body sends hormones that raise blood sugar until it reaches a typical level and hormone secretion slows. when a person is jogging, the body sends hormones that continually decrease the rate of oxygen supply to the legs.
