Life Science
University Preparation
e-Prep Course

Biology - Life Science
Life Science is one of the ten special-designed ePrep courses by NTU to help NSFs, NSMen, and others to better prepare for their university studies, whether in the local universities in Singapore or foreign universities.
This Life Science ePrep course is developed in collaboration with the textbook publishers, Cengage, and is based on the popular textbook “Biology: The Unity and Diversity of Life” by Cecie Starr, et al., currently in its 15th edition. A hard copy of the textbook is provided to every student at no additional cost, and it also comes with excellent learning materials on life science provided by the textbook publishers. Due to time constraints, the focus of this Life Science ePrep course is on Genetics for the purpose of certification. However, materials on all the remaining 39 chapters are also provided.
To help the students to have a more complete academic preparation for their university studies, there are also lots of materials on other subjects such as physics, calculus, statistics, and other branches of mathematics, business finance, corporate finance, engineering economy, business ethics, engineering ethics, psychology, Python programming, etc., so that the students not only get to build up a strong foundation on life science, they also get to strengthen their knowledge on many other subjects as well.  Samples of the materials on life science and other subjects provided can be found below.  Most of these materials can be downloaded for later studies.
There is also a retired NTU professor acting as the tutor. He can be reached via email or WhatsApp messaging, not only during the course but beyond till the students start their university studies and have their own university tutors, and even beyond when the students require more assistance, not just regarding their academic learning, but on careers and other matters as well.

Life Science ePrep Course – Sample Materials

1. Illustrative Video

This video illustrates the translation process whereby a polypeptide chain is assembled from amino acids in the order specified by an mRNA. There are many such video lessons that illustrates the various life science principles and processes.

2. Core Concepts:

All organisms alive today are linked by lines of descent from shared ancestors.

Cells of all multicelled eukaryotes reproduce by mitosis and cytoplasmic division.

Together, these processes are the basis of growth, tissue repair, and asexual reproduction.

Because mitosis links one generation of cells to the next, it is a mechanism by which the continuity of life occurs.

All multicelled organisms use the same molecules to drive and regulate their cell cycle.

Note: This is one of the Core Concepts in the chapter on DNA Structure and Function – for more listing of core concepts in the chapter, see here.

3. Key Terms
  • Bacteriophage: virus that infects bacteria.
  • DNA sequence: order of nucleotides in a strand of DNA.
  • Autosome: a chromosome that is the same in males and females.
  • Centromere: of a duplicated eukaryotic chromosome, constricted region where sister chromatids attach to each other.
  • Chromosome: a structure that consists of DNA and associated proteins; carries part or all of a cell’s genetic information.
  • Chromosome number: the total number of chromosomes in a cell of a given species.
  • Diploid: having two of each type of chromosome characteristic of the species (2n).
  • Histone: type of protein that structurally organizes eukaryotic chromosomes.
  • Karyotype: image of an individual’s set of chromosomes arranged by size, length, shape, and centromere location.
  • Nucleosome: a length of DNA wound twice around a spool of histone proteins.
  • Sex chromosome: member of a pair of chromosomes that differs between males and females.

Note: These are some of the Key Terms in the chapter on DNA Structure and Function – for more listing of key terms in the chapter, see here

4. Critical Thinking Question and Answer


Why are some genes expressed and some not?


Some genes are expressed and some are not expressed, because not all gene protein products are needed by all cell types. In other words, a cell regulates its gene expression because it contains too many genes. For example, a brain cell and a liver cell contain the same exact DNA code (as do all the cells found within a multicellular organism); however, a brain cell needs different proteins to function properly than do liver cells. Therefore, to make their unique set of protein products, certain genes are expressed and certain genes are repressed. So, one compromise of being multicellular is that every cell contains every gene the organism needs to live. However, the majority of these genes are not needed by any specific cell at a specific time.

Note: In addition to standard types of questions, there are also many Critical Thinking Questions that encourage greater thinking and deeper understanding.

5. Data Analysis

3. Question and Answer on Engineering Economy (Cost Estimation)


A foreman supervises A, B, and eight other employees. The foreman states that he spends twice as much time supervising A and half as much time supervising B, compared with the average time spent  supervising his other subordinates. All employees have the same production rate. On the basis of equal cost per unit production, what monthly salary is justified for B if the foreman gets $3,800 per month and A gets $3,000 per month?


Let x = average time spent supervising the average employee.

Then the time spent supervising employee A = 2x and the time spent supervising employee B = 0.5x.

The total time units spent by the supervisor is then 2x + 0.5x + (8)x = 10.5x.

The monthly cost of the supervisor is $3,800 and can be allocated among the employees in the following manner: $3,800/10.5x = $361.90 / x time units.

Employee A (when compared to employee B) costs (2x – 0.5x)($361.90/x) = $542.85 more for the same units of production.

If employee B is compensated accordingly, the monthly salary for employee B should be $3,000 + $542.85 = $3,542.85.

Note: This is one of the many questions and answers on engineering economy provided at the course site so that a student who signs up for this Life Science ePrep course can also learn engineering economy.

4. Video Lessons on Business Finance (Efficient Markets)

5. Worked Example on Engineering Economy (Cost Concepts and Design Economics)


A company produces and sells a consumer product and is able to control the demand for the product by varying the selling price. The approximate relationship between price and demand is

      p=$38 + 2,700/D – 5,000/D2, for D>1,

where p is the price per unit in dollars and D is the demand per month. The company is seeking to maximize its profit. The fixed cost is $1,000 per month and the variable cost (cv) is $40 per unit.

a. What is the number of units that should be produced and sold each month to maximize profit?

b. Show that your answer to Part (a) maximizes profit.

6. Objective Question Exercise on Physics (Energy of a System)


A certain spring that obeys Hooke’s law is stretched by an external agent. The work done in stretching the spring by 10 cm is 4 J. How much additional work is required to stretch the spring an additional 10 cm?

1.  None

2.   2 J

3.   4 J

4.   8 J

5.   12 J

6.  16 J

Answer (5).

4.00 J = ½ k(0.100 m)2.

Therefore k = 800 N/m and

to stretch the spring to 0.200 m requires extra work: ΔW = ½ (800)(0.200)2 − 4.00 J = 12.0 J.

    for i in range(n):
        already_sorted = True
        for j in range(n – i – 1):
            if array[j] > array[j + 1]:
                 array[j], array[j + 1] = array[j + 1], array[j] #swap
                 already_sorted = False #there was a swap
                 print(“array after i=”, i, “and j=”, j, array)
        if already_sorted: #if no more swap

    return array

oArray = [2, 8, 9, 4, 26, 82, 56, 43]
nArray = bubble_sort(oArray)
print(“Sorted array”, nArray)

original array [2, 8, 9, 4, 26, 82, 56, 43]
array after i= 0 and j= 2 [2, 8, 4, 9, 26, 82, 56, 43]
array after i= 0 and j= 5 [2, 8, 4, 9, 26, 56, 82, 43]

array after i= 1 and j= 1 [2, 4, 8, 9, 26, 56, 43, 82]
array after i= 1 and j= 5 [2, 4, 8, 9, 26, 43, 56, 82]
Sorted array [2, 4, 8, 9, 26, 43, 56, 82]

The 1st interchange is between array[2] and array[3] as 9 is greater than 4
The 2nd interchange is between array[5] and array[6] as 82 is greater than 56
The 3rd interchange is between array[6] and array[7] as 82 is greater than 43

The 4th interchange is between array[1] and array[2] as 8 is greater than 4
The 5th interchange is between array[5] and array[6] as 56 is greater than 43
Notice than after the second round (i=1), the last but one number is the second largest number
During the third round, there is no swapping at all, implying the array is already sorted and the sorting ends.


11. Economics (The Consumer’s Optimal Choices)

Consumers' Optimal Choice

1. The consumer would like to end up on the highest possible indifference curve, but he must also stay within his budget.

2. The highest indifference curve the consumer can reach is the one that just barely touches the budget constraint. The point where they touch is called the optimum.

3. The optimum point represents the best combination of cola and pizza available to the consumer.

  • The consumer would prefer point A, but he cannot afford that bundle because it lies outside of his budget constraint.
  • The consumer could afford bundle B, but it lies on a lower indifference curve and therefore provides less satisfaction.

4. At the optimum, the slope of the budget constraint is equal to the slope of the indifference curve

  • The indifference curve is tangent to the budget constraint at this point.
  • At this point, the marginal rate of substitution is equal to the relative price of the two goods.
  • The relative price is the rate at which the market is willing to trade one good for the other, while the marginal rate of substitution is the rate at which the consumer is willing to trade one good for the other
