PRACTICE EXAM GENES AND ENVIRONMENT INTERPLAY 2023/2024
This practice exam consists of 39 multiple choice questions. The questions of this practice
exam can be on the exam of March 28th (2024) of Genes and Environment Interplay. The
answer key can be found on the last page.
In the answer key, you can also find the lecture from which the question originates. We hope
this provides you a clear understanding of which lectures you already comprehend and which
you do not yet comprehend.
Good luck!

Question 1
What could be another confounding variable that causes the Cognition-Screen association,
why and what is the concequence?
a) ADHD: in the study they measure screen effects by measuring child attention and
executive functions. Children with ADHD have lowered attention, thus, using this
method, children with ADHD are more likely to show ‘bad screen effects’, while this
is due to their ADHD and not due to excessive screen time.
b) ADHD: in the study they measure screen effects by measuring child attention and
happiness. Children with ADHD have lowered happiness, thus, using this method,
children with ADHD are more likely to show ‘bad screen effects’, while this is due to
their ADHD and not due to excessive screen time.
c) ADHD: in the study they measure screen effects by measuring child attention and
executive functions. Children with ADHD have higher attention, thus, using this
method, children with ADHD are more likely to show ‘good screen effects’, while this
is due to their ADHD and not due to excessive screen time.
d) ADHD: in the study they measure screen effects by measuring child attention and
executive functions. Children with ADHD get more screen time from their parents,
thus, using this method, children with ADHD are more likely to show ‘bad screen
effects’, this due to excessive screen time.
Question 2
Is scurvy considered a genetic disease with humans (1)? And with dogs (2)? And why (3)?
a) yes 2) no 3) because there is no genetic variabele in scurvy within the human race, but
there is in dogs.
b) yes 2) yes 3) not every human or dog has scurvy, so it’s always a genetic disease.
c) no 2) yes 3) because there is no genetic variabele in scurvy within the human race, but
there is within the dog race.
d) no 2) no 3) every human or dog has the defective scurvy gene, so it’s not a genetic
disease.
Question 3
Why is RNA designed to be instable?
a) RNA is not designed to be instable, it was an unwanted mutation and causes a lot of
problems.
b) RNA is designed to be instable because it would be very dangerous for organisms if it
would not break down to aminoacids again.
c) RNA is designed to be instable because it would cost too much energy to maintain it
in a stable state.
d) RNA is designed to be instable because there is not enough room in the body to keep
all of the RNA strings.
Question 4
Which of the following statements about DNA and RNA is/are (in)correct?
I. DNA is made from RNA.
II. DNA is a fragile nucleic acid and RNA is a stable nucleic acid.
