- Describe how Ras and p53 can alter the simplified genetic pathway controlling cell division shown below. For each of the two genes, would uncontrolled cell division result from a loss-of-function or a gain-of-function mutation? growth factors - receptors - cyclins - cyclin-dependent kinases - cell divisionYou are growing up myoblasts, C2C12 cells, to use in a myogenic study. You are using T-150 flasks with a culture area of 150 cm^2 and when confluent contains 2 x 10^7 cells. Question: You seed a culture at 8 am on Monday with 5 x 10^5 cells. Assume all survive, a generation time of 18 hours and all cells are actively dividing. When would you expect them to be confluent? A) 7:24 AM on Saturday B) 8 pm on Tuesday C) 8 am on Tuesday D) 9 pm on Thursday E) 12:48 pm on Wednesday F) They won't grow that longWhat are the two regulatory mechanisms that govern the replicative capacity of cells growing in vitro and in vivo?

What are the pros and cons of the technology, and how do these issues personally affect people?What is the importance of MPF (maturation promoting factor) regulation? What happens if the regulations fail?What happens to SA:V ratio as cell side length (cell size) continues to increase? Plot these two sets of values according to the directions below to see what the trend is when cell side length continues to increase. 1. Plot a line graph of SA:V ratio on the y-axis and cell side length on the x-axis. 2. Log transform the y-axis to make the relationship more clear using the following steps. a. Click on the y-axis values; a box will appear around the values. b. Right click inside the box and choose the Format Axis command from the shortcut menu that appears. c. When the Format Axis dialog box appears, select the Axis Options entry from the list box. d. Enter the values from the screenshot in the Axis Options. 3. Properly title and label this graph. 4. Explain what happens to the surface area to volume ratio as cell side length (cell size) continues to increase. What are the implications for very large cells? What are the implications for very small cells? (Use excel spreadsheet)
- Which of the following are the correct order of steps needed for guard cells to respond to ligth? Select one: O a. Light hits guard cells, guard cells actively pump potassium and chloride out, water follows the ions out(lower water potential), guard cells lose water and open O b. Light hits guard cells, guard cells actively pump potassium and chloride out, water follows the ions out(lower water potential), guard cells lose water and close O c. Light hits guard cells, guard cells actively pump protons out, protons escort chloride ions in, water follows the ions (lower water potential), guard cells become turgid and open O d. Light hits guard cells, guard cells actively pump protons in, water follows the protons (lower water potential and concentration gradient), guard cells become turgid and closeDescribe and connect five different outcomes that could occur due to the loss of FMRP function in the cell in the figure provided.Discuss the principles that govern the presence and maintenance of stem cells both in vivo and in vitro.
- What kind(s) of cells can develop from totipotent stem cell?Investigate the main structural difference between natural competent and un-competent cells, what is the primary reason and mechanism of natural competence?In Arabidopsis, it is well-known that a pulse of full-spectrum light during the night (in an otherwise long night) will induce flowering. This suggests that plants measure the length of night, and not the length of day. If the pulse of light during the night was blue light instead of full spectrum light, what would be the flowering time response of a plant with a knockout in cry2 (relative to wild type in the same conditions)? Explain.
