^^ correct
yes you are correct
Mitosis: Gene Expression (unit 8, lesson 6)
no name is still correct, just reposting the answers
1. When a stem cell differentiates and changes in size and shape, specific genes are being
C: expressed.
2. Which of the following describes when the cell leaves the cell cycle and no longer divides?
D: Senescence
3. During gene expression, when DNA is being transcribed into RNA, the non-coding sections are removed. The remaining coding segments are connected. This process is called
A: splicing.
4. Consider the three different types of stem cells. Each one’s ability to differentiate into new cells is slightly different. One type can differentiate into any cell, while another can only become specific cells. Select the answer that places the three types in the correct order, from widest range of differentiation to least able to differentiate (specific).
A: Totipotent, pluripotent, multipotent
5. Gene expression is determined by several factors, including
B: Chemicals in the body
