Yes, I'm good at biology, I think.

Introductory Biology
Sample Questions, Exam IV Name__________
Multiple Choice: Circle the best answer.

1. The antiparallel nature of DNA is best explained by which of
the following?
a. The two strands run in opposite directions, each has an
exposed 5' phosphate on one end and exposed 3'hydroxyl group on the other.
b. The two strands run in the same direction, making it a simple
matter to copy an identical but antiparallel strand of RNA.
c. The bases are antiparallel to the long axis of the molecule.
d. Both a and c are true.
e. None of the above are true.

2. Which of the following is the best definition of semiconservative
replication?
a. The translation of a DNA molecule into a complementary
strand of RNA.
b. The fact that a DNA molecule consists of one parental strand and one new strand.
c. The fact that the number of DNA molecules is doubled with
every other replication.
d. Both a and b are true.
e. None of the above are true.

3. Which of the following adds nucleotides to a growing
polynucleotide chain of DNA?
a. DNA polymerase
b. DNA helicase enzyme
c. RNA primer
d. RNA polymerase
e. None of the above

4. Which of the following cause the unwinding of the double helix?
a. DNA polymerase
b. DNA helicase enzyme
c. RNA primer
d. RNA polymerase
e. None of the above

5. Which of the following is the best definition of an RNA primer:
a. An RNA primer is a short piece of RNA that initiates DNA synthesis once the two strands are separated.
b. An RNA primer provides an initiation site for the first several
nucleotides in the newly forming DNA molecule.
c. An RNA primer moves the two DNA strands apart so that
formation of daughter DNA strands can begin.
d. Both a and b are true.
e. Both a and c are true.

6. In DNA replication, the lagging strand
a. is synthesized as a series of Okazaki fragments
b. is synthesized as a complementary copy of the leading strand
c. pairs with the leading strand by complementary base pairing
d. is made up entirely of RNA primers
e. is not synthesized until the synthesis of the leading strand is
completed

The first 5 questions stumped me like WTF

Is this some sort of college class? I would go with...

1. a, but c sounds right too...
2. c
3. a
4. c
5. e



EDIT: And for 6, I got a...

Yes it's just a practice exam for the REAL one tomorrow . I agree with you on most of them because those are the same answers I got but I don't believe in myself a lot . Thanks though, you added a bit more faith in me

you're welcome

you will do well on your exam tomorrow

Anybody know anything on Computing Systems Concurrency, like Java monitors, threads, Safety and Liveness Properties. I have an exam on thursday Ive been studying for the past couple days

No, I'm sorry

But if you studied you should do well

I need your help gurls, Can y'all gimme a list or something with applications of trigonometry?

I'm terrible at research

Just type "applications of trigonometry" on Google.

A few uses:

- In navigation to find the distance of the shore from a point in the sea;
- In finding the height of towers and mountains;
- In oceanography in calculating the height of tides in oceans;
- In finding the distance between celestial bodies;
- The sine and cosine functions are fundamental to the theory of periodic functions such as those that describe sound and light waves.

Architects use trigonometry to calculate ground surfaces, structural load, roof slopes and many other aspects, including sun shading and light angles.

If anyone needs help up to Calculus or science involving mathematical equations and such I can try to help.
Also can help with psychology and such
