Chapter 14 & 15 Reading Questions

Chapter 14

1.       Use the terms transcription and translation to fill in the blanks below:

a.       mRNA is related to _____________________.

b.      tRNA is related to ______________________.

2.       Answer the So Far questions on page 249.  How did you do?

3.       Go through the steps in figure 14.4.  Does it make sense to you?

4.       What three codons tell a ribosome that the polypeptide chain id done; don’t attach any more amino acids?

6.       Ask and answer (if you can) a question from page 258-259.

8.       Tell me something you understand about regulation.

9.       What can I make more clear in lecture?

Chapter 15 Please read the section on stem cells (15.5) from page277 to the end of page 283.

1.       Suppose you were telling a high school student what a stem cell is, how would you explain it in a way that is basic enough that they would understand it?

2.       What is odd about the fact that a bone cell can give rise to a nerve cell in an adult human?

3.       What was the breakthrough of 2007?  In your opinion, will it quell the stem cell debate?

5.       What can I make more clear in lecture?

 

Next Reading due 11 March

Chapter 17 Reading Questions

1.       Is a population the same as a species?  Explain.

2.       Although there are 5 agents of change, natural selection is the prince among them.  According to the authors, why is natural selection distinct?  Be careful—this is a frequently missed question.

3.       Why will genetic drift impact a large population less than a small one?

4.       What is the relationship between genetic drift and the founder effect?

5.       Tell me something you thought was interesting about the Natural Selection section beginning on page 320.

6.       Give our text’s definition of evolution:

7.       Male sea elephants are huge.  Females of the same species are small.  This might be an example of ___________________     ___________________.

8.       Describe a situation (probably hypothetical) where evolution would not happen (or would be very much reduced).

9.       Try the odd post-test questions on line.  How did you do?

10.   Why are the cocker spaniels in bad shape genetically?

11.   What can I make more clear in lecture?
