IB Biology I:
DNA Group Essay Questions

#1

Due:


1.
Se
lect one genetic disorder that a
ffects human
s

and do some research on it. Report the
details of the disease’s general characteristics, how it can be detected

(diagnosis)
,

how the
disorder is

transferre
d through genetics,

the results of the disorder,
and any treatments or a
prognosis of the disorder
.

Your research should include all of these elements but is not limited
to just these details.


**You will need at
least

3 references ot
her than your textbo
ok; only two

can be an internet
site.

So everyone will have at lease one

book source other than your text.




2.
Assume that a particular genetic condition in a mammalian species causes an inability to
digest starch. This disorder occurs with equal frequen
cy in males and females. In most cases,
neither parent of affected offspring has the condition.

a.

Describe the most probable pattern of inherit
ance for this condition. Explain

your
reasoning. Include in your discussion a sample cross(es) sufficient to verify

your
proposed pattern.

b.

Explain how a mutation could cause this inability to digest starch.

c.

Describe how modern techniques of molecular biology could be used to determine
whether the mutant allele is present in a given individual.




Requirements:



4 pag
es with correct APA in
-
text citations and bibliography



Double spaced with Times New Roman


12 size font



Minimum of 2 book sources and 2 internet cites



Essay format including thesis statement

IB Biology I:
DNA Group Essay Q
uestions

#2

Due:

1
. By using the techniques of genetic engineering, scientists are able to modify genetic materials
so that a particular gene of interest from one cell can be incorporated into a different cell.



Describe a procedure by which this can be don
e.



Explain the purpose of each step of your procedure.



Describe how you could determine whether the gene was successfully
incorporated.



Describe an example of how gene transfer and incorporation have
been used in biomedical or commercial applications.


2
.
Scientists seeking to determine which molecule is responsible for the transmission of
characteristics from one generation to the next knew that the molecule must (1) copy itself
precisely, (2) be stable but able to be changed, and (3) be complex enough

to determine the
organism’s phenotype.



Explain

how DNA meets each of the three criteria stated above.



Select
one
of the criteria stated above and
describe

experimental evidence used to
determine that DNA is the hereditary material.


3
.
What is genetic en
gineering and how does it work?

Using the correct set of terms, describe
the four steps of gene transfer using bacteri
al plasmids.



How is genetic engineering used in medicine and society?

N
ame four applications of
genetic engineering techniques. Describe
how on
e of these methods can be used.



How is genetic engineering used in agriculture?

N
ame two examples of the use of genetic
engineering, one involving plants and the second involving animals. Describe one of these
two techniques in greater detail
.

Requir
ements:

Essay Assessment Ru
bric


Report
will be assessed on the following criteria:

Format
-




Typed; proper font, marg
ins, and line spacing;
four pages in length; all pages numbered and have students
names; quotes or outside sources referenced in text; reference section done properly

(10 pts)




Composition
-



Grammar, pun
ctuation, and spelling (10 pts)





Quality of Response
-



Completeness and accuracy, references cited inside essay, written at appropriate level (30 pts)







An excellent report

(grade=A):

Format= all guidelines followe
d.

Composition= grammatically solid (use of complete sentences; proper punctuation; paragraphs that flow
well; concepts don’t skip around)

Quality of response= proper use of biological terminology; writing reflects strong understanding of all
aspects of qu
estion or problem; all aspects of solution are included and thorough; response is appropriate
for college biology students.




A good report
(grade= B to C)

Format= most guidelines followed

Composition= grammatically moderate (may be excellent in some aspect

and poor in others; or just
mediocre throughout).

Quality of response= many biological terms included and properly used; writing reflects understanding of
many aspects of the problem or question; some aspects of solution are unclear or inaccurate; respons
e
level OK (more like high school level).




A poor report

(grade= D to F)

Format= most guidelines ignored (handwritten; wrong margins or font line spacing; not page numbered;
students names not included; less than two or more than four pages in length; quot
es of information not
referenced; reference section missing).

Composition= grammatically poor throughout report (incomplete sentences; misspelled words; improper
punctuation; concepts skip around).

Quality of response= biological terms lacking or misused;
writing does not reflect understanding of most
or all concepts of problem; most aspects of solution are lacking or inaccurate; response at inappropriate
level (i.e., grade school, brain surgeon).


APA Citation Example:
ALWAYS indent any line after the firs
t line in work cited.
