Question loops about DNA
page construite le 26/12/2025 par JBoscq
The aim of this session is to review some simple principles about DNA, from the perspective of Anglo-Saxon high schools, but above all to improve pronunciation, reading, and conversation in English on this very important topic.
A- The DNA RAP
listenning and answering
Listen and try to say what is the message of the next song.
B- The DNA memory
Writing, listenning
=> Remember as well as about DNA
1) Report six words connected with ‘DNA’.
2) an assistant is needed to write the words on the board.
3) Tell us one of your words and the assistant will report it on the board.
4) Maybe we could link some of these words and connect them with a topic such as
- Structure or organisation
- Chemical components
- Origin
- Role or function
- Use or developed experiments or tests
C- What do you know about DNA
learning and speaking
To assess if every body is OK with this knowledge
Watch this video about DNA

Then write each concept about DNA
and do the quiz: https://www.footprints-science.co.uk/index.php?quiz=DNA
D- Keep the line
learning and speaking
To assess if every body is OK with this knowledge, we will play question loops.
• There is a group, each member has a question and an answer to another question but there is a loop of theses questions and answers that is to say that the game could be played forever …
sample :
In your team, each member will got a line:
- the second loop has to be quicker than the first, and so on !
- one member begins the loop reading the question on the right part of the paper
- another member of the team must have the answer and gives it and then asks the question on her/his paper
- and so on till the first member answers a question and reasks her/his question
First group:
A : What does DNA stand for ?
B : DNA stands for deoxyribonucleic acid
A : Where is DNA mostly located ?
B : DNA is mostly located in the nucleus of each cell more precisely in chromosome structure visible during cell division
A : What is the structure of DNA ?
B : DNA structure is a double helix, that is to say two twisted strands
A : What are the components of a DNA strand ?
B : A DNA strand is a sequence of nucleotides which are complementary to the ones belonging to the second strand of the molecule
A : Is there any rule for nucleotide pairing ?
B : Adenine nucleotide pairs with thymine nucleotide and guanine nucleotide pairs with cytosine nucleotide
A : Is there any message in DNA ?
B : Genes are messages : one DNA molecule contains many genes
