DNA (deoxyribonucleic acid) and mRNA (messenger ribonucleic acid)
molecules are both made up of nucleotide units bonded together in long
chains. DNA nucleotides are made up of three sub-units: deoxyribose
sugars, nitrogen-containing bases and phosphate groups. Similarly, mRNA
nucleotides are made up of ribose sugars, nitrogen-containing bases and
phosphate groups.
Les molécules de l`ADN (acide désoxyribonucléique) et l’ARNm (acide
ribonucléique messager) sont à la fois constitués de motifs nucléotidiques liés
ensemble dans de longues chaînes. Les Nucléotides de l’ADN sont constitués
de trois sous-unités: les sucres désoxyribose, les bases contenant de l’azote et
les groupes phosphate. De même, les nucléotides d’ARNm sont constitués de
sucres ribose, des bases contenant de l’azote et les groupes phosphate.
Two strands (long chains) of DNA bond together and wrap around each other
to form the classic, double helix structure discovered by Watson and Crick. The
long chain of mRNA remains as a single strand after it has been transcribed
from a DNA double helix.
Deux brins (longues chaînes) d’ADN sont lies ensemble et enroules autour
de l’autre pour former le classique, structure en double hélice découverte par
Watson et Crick. La longue chaîne de l’ARNm reste sous forme de simple brin
après qu’il a été transcrit à partir d’une double hélice d’ADN.
K’NEX Education uses distinct K’NEX pieces and color-coding to represent the
various molecules and bonds that form DNA and mRNA. Use the following
nucleotide “Key” to determine which K’NEX pieces you will need for the DNA
and mRNA models you will build as part of this series of activities.
K’NEX Education utilise des morceaux distincts de K’NEX et codage couleur
pour représenter les différentes molécules et les liens qui forment l’ADN et
l’ARNm. Utilisez le nucléotide “Key” suivant pour déterminer quelles pièces
K’NEX vous aurez besoin pour l’ADN et les modèles d’ARNm vous allez
construire dans le cadre de cette série d’activités.
